Flutter Updates

Flutter is a popular open-source framework for building cross-platform mobile applications with a single codebase. A key component of any Flutter app is the AppBar, a widget that typically displays at the top of the screen with titles, navigation icons, and action items. Customizing the AppBar is crucial as it enhances the visual appeal and aligns the app’s interface with the overall theme.  When working with Flutter, you might often need to flutter change Appbar color to match your app’s design. There are various ways to customize the AppBar, from setting a unique Appbar flutter color for individual pages to applying a global theme across the entire application.  By exploring different Appbar flutter examples, you can learn how to change flutter Appbar color and text and icon colors, ensuring that your AppBar looks exactly how you want it to. What is an AppBar in Flutter? The AppBar in Flutter is a prominent user interface component that sits at the top of the screen, serving as a toolbar that provides navigation and action options to the user. It is a core part of the Scaffold widget, which is used to create the basic visual layout structure of the app. The primary purpose of the AppBar is to give users quick access to important flutter Appbar actions and navigation options. It typically includes the title of the screen, a back button or flutter Appbar menu button for navigation, and one or more action buttons for key functionalities like search, settings, or other frequently used actions. The basic structure of the AppBar consists of several key components: Title: This is usually an Appbar text color flutter widget that displays the title of the current screen. Leading: A flutter Appbar leading widget displayed before the title, often used for navigation controls like a back button or a menu icon. Actions: A list of widgets displayed after the title, typically used for action buttons like search or settings. FlexibleSpace: An optional widget that can be used to create more complex AppBar designs, such as adding an image or gradient background. Bottom: An optional widget that can display additional information or controls, often used for tabs. How to Add Color in the Flutter Appbar? Adding color to the Flutter AppBar is a straightforward process that enhances the visual appeal of your application. To change the AppBar color theme, you can use the `backgroundColor` property, which allows you to set a specific color that matches your app’s theme and branding. To begin with, you need to specify the color you want to use. Flutter provides a wide range of colors through the MaterialColor class. You can also define custom colors using the Color class. Here’s a simple example of how to set the AppBar color: AppBar( title: Text(‘Home’), backgroundColor: Colors.blue, // Change the color here ) flutter custom appbar by defining it with the Color class, like this: AppBar(   title: Text(‘Home’),   backgroundColor: Color(0xFF42A5F5), // Custom color using hex code ) How to Change the AppBar Color in Flutter? Changing the color of the AppBar in Flutter can be done in several ways. Below are the various methods to customize the AppBar color to suit your app’s design and branding needs. Using BackgroundColor Property The simplest way to change the AppBar color is by setting the backgroundColor property directly within the AppBar widget. This allows you to specify a color for the AppBar on a specific screen. AppBar( title: Text(‘Home’), backgroundColor: Colors.blue, // Set the AppBar color ) Setting Global AppBar Color via ThemeData To ensure a consistent AppBar color across the entire app, you can define the color in the ThemeData of your main application widget. This approach sets a global AppBar color. MaterialApp(   theme: ThemeData(     appBarTheme: AppBarTheme(       color: Colors.green, // Global AppBar color     ),   ),   home: MyHomePage(), ) Changing AppBar Color Dynamically at Runtime You can change the AppBar color dynamically during runtime by updating the state of the widget. This is useful for scenarios where the AppBar color needs to change based on user actions. AppBar( title: Text(‘Dynamic Color’), backgroundColor: _appBarColor, // Use a variable for dynamic color ) Using a Custom AppBar Widget Creating a custom AppBar flutter widget allows for more flexibility and reuse across different screens. This can include custom colors and other properties class CustomAppBar extends StatelessWidget implements PreferredSizeWidget { final Color backgroundColor; CustomAppBar({this.backgroundColor}); @override Widget build(BuildContext context) { return AppBar( backgroundColor: backgroundColor, title: Text(‘Custom AppBar’), ); } @override Size get preferredSize => Size.fromHeight(kToolbarHeight); } Applying Gradients with FlexibleSpace Property For more advanced customization, you can use the FlexibleSpace property to apply gradients or other complex designs to the AppBar.   AppBar(   title: Text(‘Gradient AppBar’),   flexibleSpace: Container(     decoration: BoxDecoration(       gradient: LinearGradient(         colors: [Colors.blue, Colors.purple],         begin: Alignment.topLeft,         end: Alignment.bottomRight,       ),     ),   ), ) Using the PreferredSizeWidget to Customize AppBar The PreferredSizeWidget allows you to customize the size and color of the AppBar, providing additional flexibility. AppBar( title: Text(‘Preferred Size AppBar’), backgroundColor: Colors.orange, bottom: PreferredSize( preferredSize: Size.fromHeight(20.0), child: Container( color: Colors.orangeAccent, height: 20.0, ), ), ) Integrating with SliverAppBar for Flexible Color Control The SliverAppBar flutter property provides flexible color control and is useful for implementing a scrollable AppBar that changes color based on scroll position. SliverAppBar( title: Text(‘Sliver AppBar’), backgroundColor: Colors.red, expandedHeight: 200.0, flexibleSpace: FlexibleSpaceBar( background: Container( color: Colors.redAccent, ), ), ) Using Scaffold Widget You can set the AppBar color by specifying it within the flutter scaffold Appbar color widget, which provides the overall structure for your app’s visual elements. Scaffold( appBar: AppBar( title: Text(‘Scaffold AppBar’), backgroundColor: Colors.teal, ), ) Using Brightness Property The brightness property of the AppBar can be used to change the AppBar color to dark or light themes. AppBar( title: Text(‘Brightness AppBar’), backgroundColor: Colors.grey, brightness: Brightness.dark, // Set the brightness to dark )   Common Issues Faced While Changing AppBar Colors and Their Solutions Color Not Applying Issue: The specified color does not appear on the AppBar. Solution: Ensure the backgroundColor property is correctly set and not overridden by the theme. Verify no conflicting settings in

Creating A Simple WebView Widget Once you have set up your project and added the WebView plugin, follow these steps to create a simple WebView widget in Flutter: Import The WebView Package: Open the Dart file where you want to add the WebView widget (e.g., main.dart). Import the WebView package at the top of the file: import ‘package:webview_flutter/webview_flutter.dart’;  Stateful Widget: Define a new StatefulWidget to hold the WebView: class WebViewExample extends StatefulWidget { @override _WebViewExampleState createState() => _WebViewExampleState(); } Create the corresponding State class: class _WebViewExampleState extends State<WebViewExample> { @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text(‘Flutter WebView Example’), ), body: WebView( initialUrl: ‘https://www.example.com’, javascriptMode: JavascriptMode.unrestricted, ), ); } } Integrate WebView Widget: In the State class, replace the body of the Scaffold with the WebView widget: body: WebView( initialUrl: ‘https://www.example.com’, javascriptMode: JavascriptMode.unrestricted, ), Set the initialUrl to the web page you want to load. You can change https://www.example.com to any URL of your choice. After this, set the javascriptMode to JavascriptMode.unrestricted to enable JavaScript in your Flutter web app. Add Loading Indicator (Optional): To add a Flutter WebView loading indicator, you can use a Stack widget to overlay a loading spinner on top of the WebView while it loads: class _WebViewExampleState extends State<WebViewExample> { bool isLoading = true; @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text(‘Flutter WebView Example’), ), body: Stack( children: [ WebView( initialUrl: ‘https://www.example.com’, javascriptMode: JavascriptMode.unrestricted, onPageFinished: (finish) { setState(() { isLoading = false; }); }, ), isLoading ? Center(child: CircularProgressIndicator()) : Stack(), ], ), ); } } Advanced WebView Customization Advanced WebView customization in Flutter allows developers to create highly interactive and responsive web experiences within their apps. Handling navigation and page load events is crucial for controlling the user flow and improving the app’s usability.  By listening to page start and finish events, you can provide real-time feedback, such as showing a loading

Flutter’s popularity has grown immensely over the last few years. The main reason is that they continue to provide evidence of growth with new updates. Flutter 3, announced almost 3 months ago, was a huge milestone that offered reliable support for application development for all six platforms. But they didn’t just stop there. On August 31, Flutter announced the launch of Flutter 3.3 at the Flutter Vikings conference. The version has merged around 5,687 pull requests.  The update has added some more refinements and improvements to Flutter 3 like Dart 2.18 support, new components of material 3, Scribble, some exciting extensions, and much more. Let’s have a look. Framework Features Introducing Global Selection Flutter didn’t really show good behavior when it came to text selection. You couldn’t select the widgets by default with a single swiping gesture. But no more of that fuss. Flutter 3.3 has introduced this new feature of the “SelectableArea” widget, allowing adaptive selection controls to web app developers. To get the feature just wrap your route body with the widget of “SelectableArea”. Flutter will do the rest for you. Rich Text Editing with Text Input Flutter 3.3 has now improved its rich text editing support. Now you can receive granular text updates from “TextInputPlugin”. In previous updates, the “TextInputPlugin” only provided the new states with no delta between the old and the new. But “TextEditingDeltas” and “DeltaTextInputClient” have replaced this informational gap. An Improved Touchpad (trackpad) Input Flutter 3.3 offers improved touchpad input support for its users. With this feature, you get a much smoother and richer control, further reducing any chances of misinterpretation. Say goodbye to clicking and dragging, simply manipulate content with the pointer on the touch screen. With a wide range of different touch gestures, there won’t be any awkward interactions. You can further read about the pan gesture, zoom gesture, rotate gesture, and other details here. A Jump to Dart 2.18 Like most of the past Flutter launches, Flutter 3.3 has also bumped up Dart language by introducing Dart 2.18. The 2.18 version has extended its support to Swift and Objective-C codes with “ffigen” – an API wrapper generation tool. The Flutter 3.3 update has streamlines the process of making API calls. This is surely pleasing news for iOS and Mac developers. The developers of Android and iOS are also allowed to use platform-specific code for the required HTTP requests. Scribble it! Flutter 3.3 now also supports Scribble – a free-hand drawing tool for iPad using the input of Apple Pencil. It has already been enabled by default on “TextField”, “Cupertino TextField” (ios-style textfield), and “EditableText”. Upgrade to Flutter 3.3 to get this feature.  Windows Desktop  In previous Flutter versions, you could only set your windows desktop application’s version by the file that’s specific to the window app itself. But now, you can set your app versions and build arguments from the project “pubspec yaml” file. Now it’s easy to enable auto-updating and get the recent version to your client. Material Design 3 is Here! Material design 3 new components have now been incorporated in the Flutter 3.3 version with updates on “Chips”, “IconButton” and medium and large variants of “AppBar”. The following images will help you get a better idea. Impeller – A new rendering Engine on its Way Flutter is also releasing a new replacement for Skia. Flutter developers can now test this new rendering layer – Impeller. The purpose of this improvement is to give a significant boost to the Android and iOS apps with its runtime taking complete advantage of hardware-accelerated APIs like Vulkan for Android and Metal for iOS. Check out Flutter 3.7 update that just rolled out with amazing features and improvements. You can surely expect an almost silkier animation on your Flutter applications. Impeller has also removed the need for runtime shader compilation which has been a major source of frame time janks in the applications. It is being tested actively and iOS developers have been asked to submit their reviews on it too. Impeller for Android is still under process. New Packages in Flutter 3.3 go_router  Things can get complex while developing an app with complicated navigation needs. But now it’s easy to design a routing logic that will work fine across the web, desktop, and mobile through go_router. It is a Declarative Routing Package designed by the Flutter team. By providing a declarative, URL-based API, this flutter package gives you an easy way to handle deep links and navigation across different screens. VS Code Extension Enhancement  tools to your installation that will later help your development workflow. Almost every version of Flutter has released some enhancements of Visual Code Extension and Flutter 3.3 has done it too. By using Dart: Add Dependency, you can now add multiple, comma-separated dependencies in a single step. An Update on DevTools The new update comes with UX and some performance improvements to data display tables. There will be a less jittery and much faster scrolling experience of large lists of events.  How has the performance improved? Raster Cache Improvements The improvement resulted in faster image loading capability by reducing Dart GC (Garbage Collection) pressure and the need for multiple copies. Before this, for the loading of asset images, the “ImageProvider” needed the compressed data to be copied many times. By the addition of “ui.ImmutableBuffer.fromAsset”, you can load the compressed image directly into the structure utilized for decoding. The improvement has reduced the loading time to almost half of what it was before. Deprecation of 32-bit iOS The new version no longer supports iOS versions 9, 10, and 32bit iOS devices. Deprecation of Bitcode Bitcode helps you in reducing an app’s size through recompilation. In the upcoming Xcode 14 release, bitcode most probably will not be allowed for iOS app submission. Although it is disabled by default, for the projects that have it enabled, it will emit a built warning. No iOS Pointer Compression – A Step towards Stability Pointer compression reserves a huge virtual memory region for

Flutter continues to bring amazing updates with exciting features that help developers build apps more productively. Over the past couple of years, Flutter has gained much popularity in the mobile app development realm. Businesses are opting for newer and more advanced technologies to build apps to mark their presence in the online marketplace. Flutter just released its stable release Flutter 3.0, with app support for macOS and Linux desktops as well. Recently, about 3 months ago, Flutter announced support for Windows. Now, here is the latest and much-improved Flutter release with improvements to firebase integration, and new productivity and performance features. Moreover, this release has support for Apple silicon as well. In this article, we are going to cover all the new features and improvements Flutter has incorporated into Flutter 3.0. Introducing Flutter 3.0 Flutter started as an attempt to revolutionize app development. This was only possible by combining the iterative development model of the web with hardware-accelerated graphics rendering. And also the pixel-level control that was previously the preserve of games. Over the last four years since Flutter came into existence, Flutter has gradually built on these foundations by adding new framework capabilities and new widgets, deeper integration with the underlying platforms, a rich library of packages, and many performances and tooling improvements. Flutter expanded iOS and Android with web and Windows support in previous releases. And now, Flutter 3.0 brings stable support for macOS and Linux apps as well. It requires more than rendering pixels to add platform support. It includes new input and interaction models, compilation and build support, accessibility, internationalization, as well as platform-specific integration. Flutter’s goal is to give you the flexibility to take full advantage of the fundamental operating system while sharing as much UI and logic as you choose. Flutter 3 Release Date Flutter 3.0 was released on May 11, 2022. It came up with a stable version for macOS and Linux stable support and performance improvements as well. What’s New in Flutter 3.0? As flutter aims to deliver an immersive development experience to its users, Flutter 3.0 came with the most beneficial features. Firebase Integration Improvements While building an app, there is a lot more involved than a UI framework. To build an app, developers need a comprehensive approach that helps build, release, and operate the app. This includes services like authentication, data storage, cloud functions, and device testing. Different services like Sentry, AppWrite, and AWS Amplify. Firebase provides app services to Google. Moreover, developer benchmarking studies by SlashData show that 62% of Flutter developers choose Firebase for their apps. So, Flutter has been working with Firebase to expand and better integrate Flutter as a first-class integration, lately. This includes bringing the Firebase plugins for Flutter to 1.0 and adding better documentation and tooling. And also new widgets like FlutterFire UI provide developers with a reusable UI for auth and profile screens. Foldable Phone Support Interestingly, Flutter 3.0 release now also supports foldable mobile devices. New features and widgets in Flutter 3.0 allow you to create dynamic and delightful experiences on foldable devices. This only was made after a collaboration spearheaded by Microsoft. As part of this work, MediaQuery now contains a list of DisplayFeatures that describes the bounds and states of device elements. For example hinges, folds, and cutouts. In addition, the DisplayFeatureSubScreen widget now positions its child widget without overlapping the bounds of DisplayFeatures. Also, it has already been integrated with the framework’s default dialogs and pop-ups, making Flutter aware and responsive to these elements. Updated Gradle Version The generated files with Flutter tools now use the latest versions of the Gradle and Android Gradle plugins. You will need to manually bump the versions to 7.4 for Gradle, and 7.1.2 for the Android Gradle plugin for existing projects. Flutter Casual Games Toolkit Flutter is an app framework for most developers. Unfortunately, they lack knowledge about a growing community around casual game development, taking advantage of hardware-accelerated graphics support. Interestingly, Flutter supports them with open-source game engines like Flame. Flutter also aims to make it easier for casual game developers to get started. So, at I/O they announced the Casual Games Toolkit. It provides a starter kit of templates and best practices for developers along with credits for ads and cloud services. You can easily integrate Game Center on iOS and Google Play on Android devices. Dart 2.17 Flutter has announced a new Dart SDK, version 2.17 with newer upgrades and additions. This release brings Flutter’s core themes of leading productivity and platform portability. It offers new language features that include enums with member support, improved parameter forwarding to superclasses, and more flexibility for named parameters. Flutter also improved tools with a new major version of package:lints. It is a tool to support checking Dart code against Flutter’s best practices. Also a broad update of core library API documentation with rich code samples. For improved platform integration. Flutter has new templates for using dart:ffi (native C interop) in Flutter plugins, experimental support for RISC-V processors, and support for signing macOS and Windows executables. Material 3 Support in Flutter 3.0 Flutter 3.0 now supports Material Design 3, the latest design system from Material Design. Flutter 3 provides support for Material 3.0. This includes ‘Material You’ having features like dynamic color, an updated color system, typography, and many updated components. Additionally, new visual effects are introduced in Android 12 like a new touch ripple design and a stretch overscroll effect. In flutter 3.0, developers can adopt an adaptable, cross-platform design system that offers dynamic color schemes and updated visual components. Lint Package Updates Apps built with Flutter 3.0 with flutter create automatically enable the v2.0 sets of lints. Current apps, packages, and plugins are encouraged to migrate to v2.0. This tends to follow the latest and greatest best practices in the Flutter world, by running flutter pub upgrade –major-versions flutter_lints. Most of the latest lint warnings in v2 come with automated fixes. After you’ve upgraded to the latest package version in pubspec.yaml
