Extracting bottom modal sheet into separate widget looses BlocProvider flutter - flutter

Question

First of all I hope your all well in this globally very hard hitting period. I'm refactoring parts of my screens codes and I'm stuck with this.
I have a bottom modal sheet I extracted into a separate file to keep my MapScreen UI code short and clear but something goes wrong. The error I get is BlocProvider.of() called with a context that does not contain a Bloc of type TrackingBloc. Does that men that I have to declare a BlocProvider also in the separate file? Doesn't it get passed to the widget with the context:context parameter? I then tried adding it but still get the error. Can you spot what I'm doing wrong?
As always thank you very much for your time and help, especially in this very hard time.

Answer 1

I finally found out that the Bloc has to be provided to the bottom sheet via BlocProvider.value, not in the widget file ,so the working code is :
showModalBottomSheet(
isScrollControlled: true,
context: context,
builder: (modal) {
return BlocProvider.value(
value: BlocProvider.of<TrackingBloc>(context),
child: AndroidTrackingBottomSheet(
widget.key,
routeName,
isTracking,
_textEditingController),
);
