- Finalize and complete the project creation steps.
Components in Flutter
- Flutter applications generate several files and folders including:
-
pubspec.yaml: Manages assets and dependencies. -
lib/: Contains the main code and libraries. -
README.md: Documentation for the project. -
main.dart: The entry point of the application.
-
Main.dart File

-
runApp(const MyApp());launches the application. -
MyAppis defined as a stateless widget that configures the application theme and home page. -

Widgets in Flutter

Single-child Layout Widgets:
- Examples include Align, Center, and Container.
