🎯 State Management Overview

What is State Management?

State management is the process of managing and synchronizing data (state) across your Flutter application. It determines:

  • How data flows through your app
  • How UI reacts to data changes
  • How business logic is separated from UI
  • How dependencies are injected

⚔️ BLoC vs GetX vs Riverpod Comparison

Quick Comparison Table

Feature BLoC GetX Riverpod
Learning Curve Steep ⭐⭐⭐⭐ Easy ⭐⭐ Moderate ⭐⭐⭐
Boilerplate Code High Low Moderate
Performance Excellent ⚡⚡⚡⚡⚡ Excellent ⚡⚡⚡⚡⚡ Excellent ⚡⚡⚡⚡⚡

🏗️ Architecture Pattern Compatibility

MVC Pattern

BLoC Implementation

// Cubit acts as Controller
class CounterCubit extends HydratedCubit<CounterModel> {
  CounterCubit() : super(const CounterModel());
  void increment() => emit(state.increment());
}

GetX Implementation

// Controller extends GetX Controller
class CounterController extends GetxController {
  final count = 0.obs;
  void increment() => count.value++;
}

Riverpod Implementation

// Notifier acts as Controller
@riverpod
class Counter extends _$Counter {
  @override
  int build() => 0;
  void increment() => state++;
}

MVVM Pattern

BLoC Implementation

// ViewModel is a Cubit/Bloc
class CounterViewModel extends Cubit<CounterState> {
  void increment() {
    emit(CounterLoading());
    emit(CounterSuccess(value: state.value + 1));
  }
}

GetX Implementation

// ViewModel extends GetxController
class CounterViewModel extends GetxController {
  final count = 0.obs;
  void increment() {
    isLoading.value = true;
    count.value++;
    isLoading.value = false;
  }
}

Riverpod Implementation

// ViewModel is an AsyncNotifier
@riverpod
class CounterViewModel extends _$CounterViewModel {
  @override
  Future<int> build() async => 0;
  
  Future<void> increment() async {
    state = const AsyncValue.loading();
    state = await AsyncValue.guard(() async {
      return (state.value ?? 0) + 1;
    });
  }
}
