Flutter has become a popular mobile application development framework due to its simplicity and efficiency. Flutter's widgets, which are pre-built and can be customized to meet specific needs, make it an ideal choice for developing robust and user-friendly Flutter sample apps.
Flutter's hot reload feature allows for real-time editing, saving developers a significant amount of time in the development process. Flutter is a great choice for developing Flutter sample apps that run on both Android and iOS platforms. In this blog post, we will explore the best Flutter apps and the top three Flutter example apps.
What Is Flutter?
Flutter is a mobile application development framework that allows developers to create high-performance, high-fidelity, apps for iOS and Android. Flutter uses Dart programming language which is similar to Java and is compiled to native code for both iOS and Android.
Flutter has an extensive collection of pre-built widgets that are customizable, making it a great choice for developing high-quality, responsive, and beautiful applications.
Getting started with Flutter
To get started with Flutter, you need to download and install the Flutter SDK, which includes the Flutter framework and the Dart SDK. Flutter can be used with any text editor or IDE, but it's best to use Android Studio or Visual Studio Code with the Flutter and Dart plugins installed.
Once you have installed the Flutter SDK, you can create a new project using the Flutter CLI by running the command "flutter create <project_name>".
Mobile App development with Flutter
Developing an app with Flutter involves creating a set of widgets that are used to build the user interface. Widgets in Flutter are similar to React components and are either stateless or stateful. Stateless widgets are immutable, meaning they cannot change once created. Stateful widgets, on the other hand, can change their state during the lifetime of the app.
Flutter allows developers to create custom widgets and combine them to create complex user interfaces. Flutter also provides support for animations, navigation, and routing, making it easy to create a smooth and seamless user experience.

Why are Flutter Example Apps Important?
Example or Flutter sample apps are important because they allow developers to see how to use Flutter to build real-world apps. They help to provide a blueprint for building apps and provide a starting point for developers to create their apps.
Example apps can be used to learn how to use various widgets, navigation, routing, and other features of the Flutter framework. They can also be used as a reference when building new apps.

The app has a home screen with two buttons that allow users to navigate to a second screen or a third screen. The second screen has a back button that allows users to navigate back to the home screen.
The app uses the MaterialPageRoute class to define the routes for navigating between screens. The app also uses the Navigator.push and Navigator.pop methods to navigate between screens and return to the home screen.
The source code for the navigating and routing sample app can be found on the Flutter website. The code is well-organized and easy to understand, making it a great resource for developers who are learning how to use navigation and routing in their Flutter apps.
3. Testing Sample
The testing sample app demonstrates how to write tests for a Flutter app using the Flutter test package. The app has a simple widget that displays a number and a button that increments the number when pressed. The app includes unit tests that test the functionality of the widget and integration tests that test the interaction between the widget and the button.
The testing sample app uses the Flutter test package to write tests. The package includes classes and methods for writing unit tests, widget tests, and integration tests. The app also includes the Flutter Driver API, which allows for testing of the app's user interface.
The source code for the testing sample app can be found on the Flutter website. The code is well-structured and includes comments that explain the purpose of each test, making it a great resource for developers who are new to testing in Flutter.
