Api BLoC

A Flutter library for managing API calls using the BLoC pattern. This library provides a set of classes and utilities to simplify API calls and manage state changes.

Features

• Easily manage API calls and state changes using the BLoC pattern.
• Generic classes for handling various API states such as loading, success, and error.
• Customizable builder and listener functions to respond to state changes.
• Automatic disposal of the controller to prevent memory leaks.

Getting Started

To use this library, add api_bloc as a dependency in your pubspec.yaml file.

dependencies:
  api_bloc: ^1.1.0

Usage

• Create a subclass of [BlocController] with [BlocStates]. This library already provide you with FetchStates and SubmitStates, But you can create custom state by extending [BlocStates].

import 'package:api_bloc/api_bloc.dart';

class GetUserController extends BlocController<FetchStates> {
  
  @override
  Future<void> request() async {
    Response response = await http.get(Uri.parse('https://base.url/api/user'),
      onProgress: (double progress) {
         emit(FetchLoadingState<double>(data: progress));
         }
      );
  
     UserModel model = UserModel.fromJson(response.data);
     emit(FetchSuccessState<UserModel>(data: model));
  }
}

• Put the controller inside [ApiBloc] widget.

import 'package:api_bloc/api_bloc.dart';

ApiBloc(
  controller: GetUserController(),
  builder: (context, state, child) {
    if (state is FetchSuccessState<UserModel>) {
      return Text('Username: ${state.data!.username}');
    } else if (state is FetchErrorState){
      return Text('Error occurred: ${state.message}');
    } else {
      return CircularProgressIndicator();
    }
  },
);
