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 {
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> 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 {

FaltasBloc faltasBloc;
ReviewFaltasEstudiante(this.faltaModel);

@OverRide
Widget build(BuildContext context) {
faltasBloc = BlocProvider.of(context);
// TODO: implement build
return InkWell(

print('${faltasBloc.fal[0].idNovedad} esto es prueba de que si cogio el Bloc'); /// HERE DOES WORK

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