✨ Key Features

• 🧩 Modular Architecture - Independent, reusable modules
• 💉 Dependency Injection - Built-in DI with auto-dispose
• 🛣️ GoRouter Integration - Type-safe and declarative navigation
• 🎭 Event System - Event-driven communication between modules
• 🚀 Performance - Lazy loading and efficient memory management
• 🛡️ Type Safety - Fully type-safe with compile-time error detection

🔄 Migration Guide (v4 → v5)

Migrate from the old binds() list to the new binds(Injector i) function.

What Changed?

Starting with v5.0, GoRouter Modular now uses auto_injector as the new dependency injection system. The bind registration system changed from returning a list to using a function with an injector. Binds are now injected using .new, and it's important to always type your dependencies for better type safety and inference.

❌ Old Way (v4.x)

class MyModule extends Module {
  @override
  FutureOr<List<Bind<Object>>> binds() => [
    Bind.factory<ApiService>((i) => ApiService()),
    Bind.singleton<DatabaseService>((i) => DatabaseService()),
  ];
}

✅ New Way (v5.x)

class MyModule extends Module {
  @override
  FutureBinds binds(Injector i) {
    // Using .new with auto_injector - remember to type your dependencies!
    i.add<ApiService>(ApiService.new);
    i.addSingleton<DatabaseService>(DatabaseService.new);
  }
}

Migration Steps

1. Change Method Signature

// Old (v4.x)
@override
FutureOr<List<Bind<Object>>> binds() => [
  Bind.singleton<MyService>((i) => MyService()),
];

// New (v5.x) - Using auto_injector with .new
@override
FutureBinds binds(Injector i) {
  // Always type your dependencies!
  i.addSingleton<MyService>(MyService.new);
}

⚠️ Important: Always type your dependencies (e.g., <MyService>) when using .new to ensure proper type inference and safety.

2. Update Registration Syntax

// Old (v4.x)
Bind.singleton<ApiService>((i) => ApiService())

// New (v5.x) - Using .new with auto_injector
// Remember to type your dependencies!

i.addSingleton<ApiService>(ApiService.new)
//or
i.addSingleton<ApiService>(()=> ApiService())

3. Use Keys When Needed

@override
FutureBinds binds(Injector i) {
  // Using .new with auto_injector - always type your dependencies!
  i.addSingleton<ApiService>(ApiService.new, key: 'main');
  i.addSingleton<ApiService>(ApiService.new, key: 'backup');
}

Benefits

• ✅ Cleaner syntax - No more Bind wrapper
• ✅ Better performance - Direct registration
• ✅ Easier to read - More intuitive API
• ✅ Same functionality - All features preserved
