riverpod_repo 1.0.5

A Lib to build Riverpod providers based on the reposirory interfaces.

Repo Generator with Riverpod

Getting Started

This is a Flutter code generator to generate Riverpod Providers based on the Repository method

How To

1. Create a abstract class (Interface for your repository)
2. Add @riverpodRepo annotation to your interface class
3. Add part directive for .g.dart and .repo.g.dart

part 'data_repo.g.dart';
part 'data_repo.repo.g.dart';

4. Create a provider to access the implementation of your repository
5. Run the builder
6. It will create a Riverpod Providers for each abstract methods which defined in your repositrory

Example

// File data_repo.dart

import 'package:riverpod_annotation/riverpod_annotation.dart';
import 'package:riverpod_repo/annotations.dart';

part 'data_repo.g.dart';
part 'data_repo.repo.g.dart';

@Riverpod(keepAlive: true)
RepoData repoData(RepoDataRef ref) => RepoDataImpl();

@riverpodRepo
abstract class RepoData {
  Future<List<String>> getBooks({String search = '', String categoryId = ''});

  Future<List<int>> getTopGenres();

  Future<List<bool>> getTopBooksByGenre(String genreId, {String search = ''});

  Future<List<String>> getCategories({String search = ''});
}

class RepoDataImpl implements RepoData {
  @override
  Future<List<String>> getBooks({String search = '', String categoryId = ''}) {
    throw UnimplementedError();
  }

  @override
  Future<List<String>> getCategories({String search = ''}) {
    throw UnimplementedError();
  }

  @override
  Future<List<bool>> getTopBooksByGenre(String genreId, {String search = ''}) {
    // TODO: implement getTopBooksByGenre
    throw UnimplementedError();
  }

  @override
  Future<List<int>> getTopGenres() {
    // TODO: implement getTopGenres
    throw UnimplementedError();
  }
}

This will generate following providers in data_repo.repo.g.dart

// GENERATED CODE - DO NOT MODIFY BY HAND

part of 'data_repo.dart';

// **************************************************************************

@riverpod
Future<List<String>> repoDataGetBooks(RepoDataGetBooksRef ref,
    {String search = '', String categoryId = ''}) {
  return ref.watch(repoDataProvider).getBooks(
        search: search,
        categoryId: categoryId,
      );
}

@riverpod
Future<List<int>> repoDataGetTopGenres(
  RepoDataGetTopGenresRef ref,
) {
  return ref.watch(repoDataProvider).getTopGenres();
}

@riverpod
Future<List<bool>> repoDataGetTopBooksByGenre(
    RepoDataGetTopBooksByGenreRef ref, String genreId,
    {String search = ''}) {
  return ref.watch(repoDataProvider).getTopBooksByGenre(
        genreId,
        search: search,
      );
}

@riverpod
Future<List<String>> repoDataGetCategories(RepoDataGetCategoriesRef ref,
    {String search = ''}) {
  return ref.watch(repoDataProvider).getCategories(
        search: search,
      );
}

Important

1. The providers will be prefixed with the Repo Class name

@riverpodRepo
abstract class RepoData {
}

2. Repo Class name and the provider you create for that class names should be same

@Riverpod(keepAlive: true)
RepoData repoData(RepoDataRef ref) => RepoDataImpl();
