loader 0.0.1

helps with loading required data

LoadingMixin

initiate required data before doing a full rebuild

class DataRow extends StatefulWidget {
  
  final int index;
  
  DataRow({Key key, this.index}) : super(key: key);
  
  @override
  _DataRowState createState() => _DataRowState();
}

class _DataRowState extends State<DataRow> with LoadingMixin<DataRow>{
  
  String data;
  
  @override
    Future<void> load() async{
      data = await DataProvider.getData();
    }
  
  @override
  Widget build(BuildContext context) {
    if(loading) return Container();
    if(hasError) return Text(error);
    return Text(data);
  }
}

Loader

an alternative to FutureBuilder

class Banner extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      child: Center(
        child: Loader<String>(
          load: () async{
            return await retriveBannerText();
          },
          builder: (context, value){
            return Text(value);
          },
          errorBuilder: (error) => Text(error, style: TextStyle(color: Colors.red),),
        ),
      ),
    );
  }
}
