Update singular value in flutter dart redux

I have the following BuiltMap get map; in the BowlerState. It contains BowlerEntity objects. I want to update a particular bowler in this map. My BowlerUpdate action contains the values that need to be updated in that particular bowler. How do I do so? I need to modify the below reducer to do so.

One reducer is like this 

BowlerState _updateBowlerAge(
    BowlerState bowlerState, SaveBowlerAgeSuccess action) {
  return bowlerState.rebuild((b) => b
      ..map[action.bowler.id] = action.bowler
  );
}

Use replace() to replace the desired BowlerEntityBuilder.

BowlerState _updateBowlerAge(BowlerState state, SaveBowlerAgeSuccess action) {
  final newMap = state.map[action.bowler.id].toBuilder()
    ..replace(action.bowler);
  return state.rebuild((b) => b
    ..map.replace(newMap));
}
