Unable to find Bloc of type _BlocProvider<FaltasBloc>

[freynetraul]

I have been killing my head with this problem, I do not know why it is happening, the worst thing is that it happens to me in a single sequence, here is my code

class FaltasEstudiante extends StatelessWidget { @override Widget build(BuildContext context) { // TODO: implement build return BlocProvider( child: Scaffold( body: ListFaltas(), floatingActionButton: FloatingActionButton( backgroundColor: Colors.white, foregroundColor: Colors.blue, child: Icon( Icons.add, size: 29.0, ), onPressed: () { Navigator.push(context, MaterialPageRoute(builder: (context) { return InputsFaltaScreen(); })); }, ), ), bloc: FaltasBloc()); } }

class ListFaltas extends StatefulWidget { ListFaltas({Key key}) : super(key: key);

@override _ListaFaltas createState() => _ListaFaltas(); }

class _ListaFaltas extends State<ListFaltas> { SessionBloc estebloc; FaltasBloc faltasBloc; EstudiantesBloc estudiantesBloc;

@override Widget build(BuildContext context) { estebloc = BlocProvider.of(context); faltasBloc = BlocProvider.of(context); estudiantesBloc = BlocProvider.of(context); faltasBloc.initE(estudiantesBloc.modelEstudiante.identificacion, 0); return StreamBuilder( stream: faltasBloc.counterStreamE, builder: (BuildContext context, AsyncSnapshot<List<FaltaModel>> snapshot) { if (estebloc.isOffline) { return SinConxion(); //construir pantalla sin conexión } else { if (snapshot.data != null) { if (snapshot.data.length == 0) { return Center(child: Text("No hay datos para mostrar")); } return ListView.builder( itemBuilder: (context, index) { return ReviewFaltasEstudiante(snapshot.data[index]); }, itemCount: snapshot.data.length); } else { return carga(); } } }); } }

class ReviewFaltasEstudiante extends StatelessWidget { FaltaModel faltaModel; FaltasBloc faltasBloc; ReviewFaltasEstudiante(this.faltaModel);

@override Widget build(BuildContext context) { faltasBloc = BlocProvider.of(context); // TODO: implement build return InkWell( onTap: () { print('${faltasBloc.fal[0].idNovedad} esto es prueba de que si cogio el Bloc'); /// HERE DOES WORK Navigator.push(context, new MaterialPageRoute( builder: (context) => new VerDetalle(detallefalta)) ); }, child: Card( color: Colors.blueAccent, margin: EdgeInsets.only(left: 10.0, right: 10.0, top: 5.0, bottom: 3.0), elevation: 5, child: Container( padding: EdgeInsets.only(left: 5.0, right: 3.0, top: 10.0, bottom: 5.0), child: Column( children: <Widget>[ Container( margin: EdgeInsets.only( left: 25.0, right: 10.0, top: 5.0, bottom: 3.0), child: Row( children: <Widget>[ Text( "TIPO ${faltaModel.tipo}", style: TextStyle( color: Colors.white.withOpacity(1.0), fontSize: 18, fontFamily: 'Jost', fontWeight: FontWeight.bold), ), ], ), ), Container( margin: EdgeInsets.only( left: 25.0, right: 10.0, top: 5.0, bottom: 3.0), child: Row( children: <Widget>[ Text( "Fecha ${faltaModel.fecha} ", style: TextStyle( color: Colors.white.withOpacity(1.0), fontSize: 14, fontFamily: 'Jost', ), ), ], )), Container( color: Colors.black12, margin: EdgeInsets.only( left: 15.0, right: 15.0, top: 5.0, bottom: 5.0), padding: EdgeInsets.only(top: 0.8, bottom: 0.8), ), Container( color: Colors.blueAccent, child: Row( mainAxisAlignment: MainAxisAlignment.end, children: <Widget>[ Container( child: Column( children: <Widget>[ Text( "${faltaModel.diligenciador} ", style: TextStyle( color: Colors.white.withOpacity(1.0), fontSize: 16, fontFamily: 'Jost', fontWeight: FontWeight.bold), ), Text( "${faltaModel.sede}", style: TextStyle( color: Colors.white.withOpacity(1.0), fontSize: 16, fontFamily: 'Jost', ), ) ], )), Container( margin: EdgeInsets.only( left: 10.0, right: 5.0, top: 5.0, bottom: 5.0), height: 85, width: 85, decoration: BoxDecoration( shape: BoxShape.circle, color: Colors.white), ), ], ), ) ], ), ),

  ),
);

It would be nice if you could prepare a minimal repo to reproduce this and share it with me.
