Learn Flutter SDK Setup | Flutter Basics

Definition

The Flutter SDK is a collection of tools, libraries, and APIs for building cross-platform mobile apps.

When you use the Flutter SDK, you gain access to three main components that power your app development. The engine is responsible for rendering graphics, handling input, and communicating with the underlying platform. The framework is a collection of Dart libraries that provide the building blocks for your app’s user interface and logic, including widgets, navigation, and state management. The tools include command-line utilities and editors’ plugins that help you create, build, test, and deploy your apps. Together, these components allow you to build high-performance apps for multiple platforms such as Android, iOS, web, and desktop from a single codebase.

main.dart


              123
            
void main() {
  print('Hello, Flutter!');
}

Dart is the programming language used for Flutter development. It was chosen because it is easy to learn, offers strong typing, and supports both just-in-time (JIT) and ahead-of-time (AOT) compilation. This allows for fast development cycles and efficient production builds, making Dart a great fit for building responsive and portable user interfaces.

main.dart


              1234567
            
String greet(String name) {
  return 'Welcome to Flutter, $name!';
}

void main() {
  print(greet('Developer'));
}

Note

Dart's fast compilation and hot reload features let you see code changes instantly, boosting your productivity when building Flutter apps.
