Keyboard pushes modalBottomSheet out of the bounds, resizeToAvoidBottomInset not working

Question

I ran into problem in a Flutter application. The keyboard pushes the modal bottom sheet up even if the Scaffold has resizeToAvoidBottomInset set to false. I want the modal bottom sheet to remain at its initial position. I will show you my code for displaying the modal bottom sheet and I will attach a video to show you the bug.

Scaffold(
    resizeToAvoidBottomInset: false,
    key: _scaffoldKey,
    body: ...
)

showModalBottomSheet(
  context: context,
  isScrollControlled: true,
  backgroundColor: Colors.transparent,
  builder: (context) => Container(
      height: MediaQuery.of(context).size.height * 0.8,
      decoration: new BoxDecoration(
        color: Colors.white,
        borderRadius: new BorderRadius.only(
          topLeft: const Radius.circular(25.0),
          topRight: const Radius.circular(25.0),
        ),
      ),
      child: SearchPlace((place, alreadyExists) {
        Navigator.pop(context);
        didSelectPlace(place, alreadyExists);
      })),
);

Hope you can help me, thanks!

Ok, so I found a solution for this issue myself.

I wanted the modal bottom sheet to occupy 80% of the screen, but it was always pushed by the keyboard. In order to fix this I wrapped the main Container in a Column widget and added an additional transparent Container with a GestureDetector (to dismiss the bottom sheet) having the height 20% of the screen. After that I wrapped the Column in a SingleChildScrollView. Now everything works as expected! I added a video below.

showModalBottomSheet(
    context: context,
    isScrollControlled: true,
    backgroundColor: Colors.transparent,
  builder: (context) => SingleChildScrollView(
    child: Column(children: [
      GestureDetector(
        onTap: () {
          Navigator.pop(context);
        },
        child: Container(
          color: Colors.transparent,
          height: MediaQuery.of(context).size.height * 0.2,
        ),
      ),
      Container(
          height: MediaQuery.of(context).size.height * 0.8,
          decoration: new BoxDecoration(
            color: Colors.white,
            borderRadius: new BorderRadius.only(
              topLeft: const Radius.circular(25.0),
              topRight: const Radius.circular(25.0),
            ),
          ),
          child: SearchPlace((place, alreadyExists) => {
                Navigator.pop(context),
                didSelectPlace(place, alreadyExists),
              })),
    ]),
  ),
);
