BlocOverrides class Null safety

This class facilitates overriding BlocObserver and EventTransformer. It should be extended by another class in client code with overrides that construct a custom implementation. The implementation in this class defaults to the base blocObserver and eventTransformer implementation. For example:

class MyBlocObserver extends BlocObserver {
  ...
  // A custom BlocObserver implementation.
  ...
}

void main() {
  BlocOverrides.runZoned(() {
    ...
    // Bloc instances will use MyBlocObserver instead of the default BlocObserver.
    ...
  }, blocObserver: MyBlocObserver());
}
