What I Learned from the Marimba App Project

During the development of this project, I gained important knowledge about several Flutter and Dart concepts:

🟣 Flutter Widgets

• MaterialApp: Provides the main structure for the app, including navigation and themes.
• Scaffold: Used as the basic visual structure for the app's layout.
• SafeArea: Ensures UI elements are positioned within the safe display boundaries.
• Column and Expanded: Help organize widgets in a flexible vertical layout.
• TextButton: Utilized to create clickable buttons that trigger sound playback.

🔵 Functions in Dart

• I practiced creating functions to improve code structure and readability.
• The playSong function was designed to handle audio playback efficiently:

void playSong(int songNumber) async {
  await _player.play(AssetSource('nota$songNumber.wav'));
}

• This helped me understand parameter passing and asynchronous programming using async and await.

🟠 Using External Packages

• I learned how to integrate the audioplayers package for audio playback.
• I practiced initializing an AudioPlayer instance and calling its .play() method to load and play audio files.

🟢 Error Handling & Debugging

• I improved my ability to identify and fix issues such as:
  • Ensuring required parameters were properly defined.
  • Correctly configuring asset paths in the pubspec.yaml file.

This project provided valuable hands-on experience with Flutter and improved my understanding of core development principles. 🚀
