Liquid Flutter Window Utils

A Flutter plugin for window utilities using Pigeon for platform-specific code generation.

Setup

This package uses Pigeon for generating platform-specific code. The Pigeon configuration is in pigeons/messages.dart.

Development

1. Install dependencies

flutter pub get

2. Generate Pigeon code

After modifying the Pigeon messages file, regenerate the platform-specific code:

flutter packages pub run pigeon --input pigeons/messages.dart

Or use the build runner:

flutter packages pub run build_runner build

3. Add new methods

To add new window utility methods:

1. Edit pigeons/messages.dart to add new methods to the WindowUtilsApi class
2. Regenerate the code using one of the commands above
3. Implement the methods in the platform-specific files (Android, iOS, macOS)
4. Add the method calls in lib/liquid_flutter_window_utils.dart

Project Structure

• pigeons/messages.dart - Pigeon API definition
• lib/messages.g.dart - Generated Dart code (do not edit manually)
• android/src/main/java/.../Messages.java - Generated Android code
• ios/Classes/Messages.h - Generated iOS header
• ios/Classes/Messages.m - Generated iOS implementation
• macos/Classes/Messages.swift - Generated macOS code

Example

// In pigeons/messages.dart
@HostApi()
abstract class WindowUtilsApi {
  bool setWindowSize(int width, int height);
  void setWindowTitle(String title);
}

// In lib/liquid_flutter_window_utils.dart
Future<bool> setWindowSize(int width, int height) async {
  final api = WindowUtilsApi();
  return await api.setWindowSize(width, height);
}
