📱 forceinject_flutter

Flutter integration for ForceInject — a zero-runtime-dependency DI container inspired by .NET Core.

✨ Features

• ForceScopeWidget — Automatically manages scoped lifetimes tied to widget lifecycle
• ForceViewModelBuilder<T> — Injects and rebuilds using reactive ValueNotifier ViewModels
• No state management dependency — works with any pattern (MVVM, Clean, Redux, etc.)
• Pure Dart and Flutter — lightweight and testable

🔁 ViewModel Lifecycle Support

ViewModels injected via ForceViewModelBuilder can now:

• Implement ForceInitializableViewModel to run init(BuildContext context) after mount
• Implement Disposable to be cleaned up automatically when the widget tree is disposed

class MyViewModel implements ForceInitializableViewModel, Disposable {
  @override
  void init(BuildContext context) {
    print('Initialized with: ${Localizations.localeOf(context)}');
  }

  @override
  void dispose() {
    print('Cleaned up');
  }
}

🧪 Example

Check out the scoped_widget_flutter_di example for a complete working app.

ForceScopeWidget(
  provider: provider,
  child: ForceViewModelBuilder<MyViewModel>(
    builder: (context, vm) => Text('${vm.count.value}'),
  ),
)

📦 Requirements

• Flutter 3.10+
• Dart 3.6+
• force_inject >= 0.2.0

💡 Use Cases

• Scoped ViewModels per screen
• Widget-driven lifetime management
• Modular app architecture

🧰 No Code Generation

ForceInject and its Flutter integration work without:

• build_runner
• annotations
• mirrors
• codegen

Use pure constructor-based registration — just like .NET Core DI.
