News app in Flutter with BLOC pattern
This example uses a CustomScrollView, JSON Rest API, BottonNavigationBar,SliverList, ClipRRect, Card, Progress Indicator, NetworkImage, Card, Column, Row, Container, InkWell, BoxDecoration.
I used this pattern to design this application.
class NewsBloc {
final _repository = Repository();
final _newsFetcher = PublishSubject<NewsModel>();
final _newsSearchFetcher = PublishSubject<NewsModel>();
final _newsLikeFetcher = PublishSubject<NewsModel>();
Observable<NewsModel> get allNews => _newsFetcher.stream;
Observable<NewsModel> get searchNews => _newsSearchFetcher.stream;
Observable<NewsModel> get likeNews => _newsLikeFetcher.stream;
fetchLikedNews() async {
NewsModel newsModel = await _repository.fetchLikedNews();
_newsLikeFetcher.sink.add(newsModel);
}
fetchAllNews() async {
NewsModel newsModel = await _repository.fetchAllNews();
_newsFetcher.sink.add(newsModel);
}
fetchSearchNews() async {
NewsModel newsModel = await _repository.fetchSearchNews();
_newsSearchFetcher.sink.add(newsModel);
}
// Set and delete from Firestore liked
addFavorit(val) async => _repository.addFavorit(val);
deliteFavorit(val) async => _repository.deliteFavorit(val);
dispose() {
_newsLikeFetcher.close();
_newsFetcher.close();
_newsSearchFetcher.close();
}
}
final bloc = NewsBloc();
