Flutter Development with Dart – Build Scalable Multi-platform Apps

The so-called browser war ended with Google’s launch of Flutter in December 2018, an open-source, UI framework for app development. Flutter development with Dart is becoming a more popular topic and demanding concern of Flutter developers. Flutter utilizes Dart, a programming language for the coding of Flutter apps. Dart’s syntax is much like JavaScript and it is an object programming language with the main concern of front-end development. Although this cross-platform framework is newer, it has become a leading priority of various companies like Cordova, React Native, and Xamarin. This powerful, general-purpose tool is highly in use today and you can find numerous Flutter applications on Play Store as well. This blog will provide everything you need to know about Flutter so you can set your Flutter development with Dart in motion. Flutter’s first stable version 1.0 created a splash in the world of application development. This was mainly because of one of the distinctive features of Flutter – use of a single codebase and programming language. Flutter development with Dart facilitate developers build a native app for both Android and iOS in a much simpler and faster way. Flutter’s development approach was also different from others, mainly because of its declarative UI writing. Before you get down to the development process, you first need to make sure you have a complete picture of the kind of UI in mind. For some developers, it improves clarity, but for others, it can create certain difficulties. Flutter’s framework consists of both an SDK – a software development kit – and its own widget-based UI library. You will find various reusable UI elements like buttons, sliders, and text inputs in this library. Dart Programming: A Language Review Google’s Dart is both a significant advantage and a notable drawback of Flutter development. The language was initially released in 2011 but it wasn’t until the launch of Flutter that the language became popular among developers. The inspiration came from other programming languages, mainly JavaScript and it is hence, Strongly Typed. You can use Dart to build just about anything on mobile, desktop, and web. When used for web applications, we have to compile Dart to JavaScript. In other words, Dart can semantically fit inside JavaScript, which is why it is simpler and easier to develop apps in Flutter. Whatever you write in Dart will compile to JavaScript. There is nothing innovative here, it is just a simple and predictable language with no special operators that could throw you off the loop. This is what makes Dart programming simple and productive. Use of Dart in Flutter: The Practical Advantages Some of the developers are quite skeptical about the use of Dart in Flutter. The language is growing steadily with time, but it is not one of the hot languages in use these days.  Does Google use Dart simply because it’s their language? That is not entirely true. Developers find learning Dart to be less of a hurdle as compared to other programming languages. Following are some practical advantages that come with the use of Dart. Flutter Pros and Cons When it’s time to develop applications, developers are most inclined toward cross-platform frameworks, but they are not restricted to Flutter only. However, within a year, Flutter usage has grown from 30% in 2019 to 39% in 2020. The users of React Native are coming towards Flutter, and this is because of the following advantages that Flutter has, over other frameworks.  Pros: Enhanced and Ideal Productivity: By using the same code base for your iOS and Android apps, you can save both time and resources. This productivity is further enhanced due to the feature of hot reload, which exists due to JIT compilation. Hot reloading allows you to catch a glance at the applied changes in real-time. The developer can simply pause the code execution, make the desired changes, and then continue where they left off. This feature not only speeds up the development process but also allows makes room for experimentation. Altogether, the entire process is faster, consumes fewer man-hours, and hence has more time-to-market speed. Ready-made Widgets: Flutter team works hard in providing you with a wide variety of ready-made widgets. They are also highly customizable and save time. Flutter also has a large set of Material and Cupertino widgets that can mimic the behavior of each design language perfectly. Achieve Native App Performance: One good thing about Flutter is that it does not rely on interpretation or any intermediate code representations. This allows similar to native app development. Through native code base and third-party integrations, developing gets easier. Skia – Flutter’s Rendering Engine: Most of the advantages mentioned above would not have been possible without Flutter’s high-performance rendering engine, Skia. Most of the famous application softwares like Chrome, Adobe, and Amazon Kindle use this graphic engine. Due to the use of Dart, Flutter compiles directly into the ARM code of mobile devices. Skia communicates with Flutter apps and in turn, Flutter accepts local events directly rather than compiling them first into JavaScript. With Skia, you can now virtually launch Flutter’s UI on any platform. This simplifies and speeds up the development process greatly. Powerful UI with Great Customization Potential: Flutter’s architecture allows the developers to build custom UI. You can customize whatever you see on the screen, regardless of the complexities. With custom designing, you can create applications that would look good on both iOS and Android by putting fundamentally lower efforts. Ready-to-use Features: Various applications make use of advanced OS-level features like Bluetooth, GPS coordinates, permission handling, and so on. With Flutter, many of these options are available through ready-to-use plug-ins supported by Google. Cons: While there are several advantages that the developers and businesses can take advantage of, there are some cons of Flutter too, which you need to be aware of before you start developing. Lesser Third-party Libraries: As mentioned earlier, Flutter is a relatively newer technology, due to which the volume of third-party libraries is limited. This reduces the speed

Dart Null Safety in Flutter – A Complete Guide

In a Flutter app, dealing with null values in the code is always a hectic task. Several runtime errors can be caused if a function has a null value. Ultimately, it will cause app crashes. Dart Null safety is a feature that handles null values. Null safety is not originally a feature of Flutter but a specification of Dart language.  Firstly, the null safety in Flutter was introduced to the Dart programming language in July 2020. After its stable release in March 2021, the null safety feature was not only available for new code but also for migrating existing Flutter apps. In this blog, we will be giving you a complete overview of Dart null safety in Flutter. Flutter is one of the most reliable and broadly used frameworks when it comes to application development. It has several features that collectively make it a perfect choice for developers to build cross-platform applications. The code reusability, single codebase system, rich libraries, fast testing, native nature, and own rendering engine are some of its features that we can’t leave undiscussed. There is another interesting and most useful feature of Flutter that is null safety.  What is Null Safety? Dart null safety in Flutter is a feature that doesn’t allow a variable to have a null value. The variable can only have a null value unless you initialize with null to that variable. This feature reduces errors and app crashes which ultimately increases user satisfaction.   Interestingly, the null safety feature shows all the errors during the compilation of the code. You don’t have to wait until the runtime to identify the errors. The basic idea behind null safety is that all variables should be initialized with some value. This will reduce any runtime errors that can be caused due to the null value.   Additionally, this feature helps developers to find out where an error occurs. Whenever you see an error message like “Unhandled Exception: type ‘String’ is not a subtype of type ‘List<int>’ in type cast” then you should check whether the data is valid before using it. Fundamentals of Dart Null Safety in Flutter Three core design principles support the null safety. These are as:  Code should be non-nullable by default A variable will be considered non-nullable unless you explicitly inform Dart that it can be null. Since non-null is the most common API choice, we chose this as the default. To gain greater flexibility, you can defer some of that checking to runtime, but you must use a feature that is textually visible in your code to do so.  Adoptability of Null safe code  In the Dart, there is a lot of code present. You can easily migrate to null safety at any time you want to, and then incrementally, part by part. Dart null safety offers you complete freedom to switch to null safety. Whenever you want to move or whatever you want to move to null safety, you can do that readily. Moreover, a single project can have null-safe or non-null-safe code changes.      Fully Sound Null Code With the Dart null safety in Flutter, you can trust the type of system. If the type system determines that a variable is not null then it can never be null and vice versa. There is no possibility that null safety would show you any inaccurate results. This allows you to optimize the code compilation. Each variable requiring a value must be correctly initialized. Additionally, null Safety makes binaries smaller, reduces bugs, and executes faster. How does Dart null safety migration work? As Dart brings many useful and exciting features to Flutter SDK, you can perform several actions with it. Surprisingly, you can also migrate your application to null safety using a dart. Here is a quick go-through of the migration of an app to null safety. To migrate an application or a package to null safety, you need to follow five major steps. These steps are: 1. Make sure all dependencies are ready for migration While migrating your application to null safety, you need to make sure all the dependencies are ready for migration. You may need to the relocation migration again after transferring the appropriate code in case any of your dependencies change during the migration.  You might need to contact the flutter package developers if any of your dependencies are not null-safe. However, an app is ready to migrate only if it can upgrade its dependencies to the prerelease versions of the path and process.   2. Migrate using the migration tool You may require tools throughout the development process while building an app. These tools help you streamline the development process by performing certain tasks. Luckily, the migration tools are there to help you analyze the nullable attributes. Interestingly, you can add nullability cues to change the attributes of a device. However, it may affect the migration quality in one way or the other.   3. Static analysis of your migrated code You can execute the pub get command in your terminal to update your packages. This will allow you to evaluate your Flutter and Dart code statically. Following are the commands which you can run to analyze your migrated code for Flutter and Dart. 4. Make sure the tests pass During the migration of your app to null safety, ensure that all the tests pass. You may need to rerun tests if you modified your package code to only accept non-nullable variables. 5. Publication of null-safe packages As soon as the migration is complete and the tests are successful, you can publish the prerelease packages. As a compliment, you should publish your package to pub.dev which is a public repository. This will help other developers to reuse the code if it aligns with their needs and requirements. How to Enable Null Safety in Flutter? Although null safety is no more an experiment in Dart, you may still need to enable null safety. Moreover, you could also need to enable null safety because the previous version

Benefits of Flutter App Development | FlutterDesk

Flutter has been the utmost priority of developers to choose when it comes to selecting a framework for app development. It is much surprising to know the fact that flutter has gained exceptional popularity in such a short period. Since Google launched flutter 3 years ago, it was not that easy for any development framework to gain the developer’s interest. But due to the obvious benefits of flutter app development, developers can’t resist going with flutter for any of their app development projects. Mobile app development trends are evolving day by day. Similarly, the technologies are trying their best to find a way to distinguish themselves from others to build robust apps. There is no doubt that flutter possesses most of the features which are necessary for delivering the best development experience. Its single codebase for cross-platform development is one of the main reasons that it dominates other platforms, straightforwardly. Many businesses look forward to hiring a flutter developer to turn their ideas into real-world easy-to-use apps. Mobile phone users have grown extremely fast in a couple of years. There is no possibility that the potential of uplifting your business with mobile apps is going to end anytime soon. Let’s move forward to getting to know what flutter is and what are the benefits of flutter app development. What is Flutter? Flutter is Google’s launched development framework that has been around us since early 2015. Its stable release came out later in 2018 as a complete and ready-to-code framework. In simple words, flutter is a cross-platform development framework for building mobile, web, and desktop apps using a single codebase. Gone are the days when you had to write the code separately to move towards another platform. Flutter has transformed the development trend and laid a transparent, fast, and productive development experience. Flutter continues to improve the developer experience and introduces newer and better features with time. Benefits of Flutter App Development Fast Development The time required to finish the developing process is the stakeholder’s major concern when it comes to mobile app development. The time required to complete a project depends upon the development framework and the resources it would take. There are a couple of useful features in Flutter that collectively make development fast. One of the main features in this regard is the hot reload feature. It works by injecting updated source code files into the running Dart Virtual Machine (VM). The Virtual Machine updates the classes with the new versions of fields and functions. After that, the Flutter framework automatically rebuilds the widget tree, allowing you to quickly view the effects of your changes. Moving forward, consider how much it would help the developer-designer relationship. For example, your designer can prompt your Flutter engineer to make changes, such as changing the position of a button. The developer can make the changes in the code and see the outcomes right away. Similarly, he will be informing the designer if the button is in the right position or not. There is no need to wait longer for the runtime, which causes delays in the consequences. Single Codebase for Multiple Platforms One of the most distinguishing and reliable benefits of flutter app development is its cross-platform development. Before flutter came into the game, it was much more time-consuming and expensive to build apps for more than one platform. Flutter is a single codebase framework, which means that you have to write the code only once. And this code will be compatible with all other platforms (mobile, web, desktop). You’ll not find any other framework that offers code reusability and allows you to write just one codebase. This cuts down development time to a much greater extent and ultimately reduces cost. Moreover, flutter has a lot of ready-to-use customizable widgets, unlike other platforms. It takes a lot of time and effort to create widgets and implement them in the app. With Flutter, you don’t have to worry about creating the widgets as there are plenty of widgets already available in it. You can select a relevant widget and readily implement it in the app saving considerable time and struggle. High-Performance Apps Application performance is probably one of the key features when building a good UX. In earlier updates, Flutter has improved rendering performance by 50 % on new iOS devices. Additionally, it reduced memory consumption by over 70%. This fact displays the great picture of the benefits of flutter app development over another software development kit (SDK) you choose to follow. It is due to the native app development of Flutter that the apps built with this framework have high performance. One of Flutter’s benefits is that it doesn’t rely on creating manual widgets. The application already has built-in widgets which minimize any performance errors in the process. Flutter does not need a JavaScript barrier to interact with native components and has a powerful rendering engine, ‘Skia’. Flutter shows comparatively high performance if we compare it with other frameworks like Ionic or react native. Best for MVPs MVPs have become a must-have asset for every startup as they can help you validate your idea and possibly get you the initial funding for your project. Flutter encourages MVP development as an open-source framework. With Flutter’s increased popularity and pace of the development process, app development becomes simplified. MVPs are small, basic app versions with minimal functionality and essential features that are easy to build and launch. We build MVPs to test the concept, collect the first feedback, and unlock growth opportunities to make a better app in the next iteration. Without an MVP, businesses can’t have an idea of how effective and productive their business could be. As it is useless to move to development blindly, you need to have an MVP developed. Flutter app development is a great choice for MVP development as this SDK is extensive, easy to understand, and delivers excellent apps. Customizable Widgets As discussed earlier, Flutter offers more than 390 widgets to help developers throughout the
