Expose `buildWhen` option through `ViewController`

The BlocBuilder class has an buildWhen parameter. I should be able to use that buildWhen parameter in the ViewController class that wraps BlocBuilder.

There are two primary interfaces I can think of:

Example 1: pass `buildWhen` through `ViewController` super constructor

class MyViewController extends ViewController<MyBloc, MyState, MyView, MyViewModel> {
  const MyViewController({Key? key})
      : super(
          key: key,
          // pass in here
          buildWhen: (previous, current) => previous != current,
        );

  @override
  MyView buildView(
    BuildContext context,
    MyBloc bloc,
    MyViewModel viewModel,
  ) {
    return MyView(
      actions: MyViewActions(bloc),
      viewModel: viewModel,
    );
  }

  @override
  MyViewModel stateToViewModel(MyState state) {
    return MyViewModel(state.todos);
  }
}

Example 2: override a `buildWhen` method from the base `ViewController` class

class MyViewController extends ViewController<MyBloc, MyState, MyView, MyViewModel> {
  const MyViewController({Key? key}) : super(key: key);

  @override
  MyView buildView(
    BuildContext context,
    MyBloc bloc,
    MyViewModel viewModel,
  ) {
    return MyView(
      actions: MyViewActions(bloc),
      viewModel: viewModel,
    );
  }

  @override
  MyViewModel stateToViewModel(MyState state) {
    return MyViewModel(state.Mys);
  }

  @override
  bool buildWhen(MyState previous, MyState current) {
    // TODO: implement buildWhen
  }
}
