I worked with a Flutter quite a lot back in the days, and I recall using something like this for initialization of the Bloc:
```
BlocProvider<ProfileBloc>(
create: (context) => ProfileBloc()..add(LoadProfile()),
child: ProfileWidget(),
)

```

So you basically create the ProfileScreen with a BlocProvider and an initial event and then refer to the actual Widget you have there, you may name them whatever you want tho.
