I have a hard time understanding why the API is not more symmetrical and easier to use for showing a
Modal or not Modal Bottom sheet. I like the straight forward approach under 2. for the Modal Bottom sheet. Why is there not a same for the non Modal?

      new InkWell(
            onLongPress: () {
                HomeScreen.scaffoldKey.currentState.showBottomSheet<Null>(
                  (context) => createBottomSheet(context, appController));
            },

      new InkWell(
            onLongPress: () {
              showModalBottomSheet<Null>(
                  context: context,
                  builder: (context) =>
                      createBottomSheet(context, appController));
            },
