flutter dropdown selected value

A dropdown button is a widget that helps users to select a value or an option from a set of values. The dropdown list is an important element in an app that increases the ease of the users using the app. In this article, we are going to learn how to implement a dropdown list in Flutter. For example, you have a form with city selection. There are two widgets that you can use to show those city details. One option is using the radio button, which allows for selecting a single value. The other option is to use DropDownButton. In scenarios like this, using a dropdown widget will be the best option. This is because you can add a large list of cities. And when the user selects a city, it will show only that selected city in particular. So, it is much more likely to provide a better user experience to the end-user.
