flutter - Mapbox bug, dark screen on Navigator push

Question

i wanted to test MapboxGL using this package https://github.com/apptreesoftware/flutter_map .

I'm testing on Nokia 5.3 , Android 10 .

So when i test it , launching the screen directly from the Main.dart , it works fine with the markers and everything .

But when i try to go to that screen after clicking on a button, i get a black screen .

Pubspec.yaml 

environment:
sdk: ">=2.8.0 <3.0.0"
dependencies:
  flutter:
    sdk: flutter
flutter_map: any #Test map
flutter_map_marker_cluster: any

so like i said when i try to reach the screen like this

InkWell(
  child: Icon(
    FontAwesomeIcons.mapMarkerAlt,
  size: 12,
  color: HexColor('#54D3C2'),),
  onTap: () {
    Navigator.of(context).push(
      MaterialPageRoute(
        builder: (BuildContext context) {
          return TestMapPage();
        },
      ),);
 },

)

and i get these in my console .
