Flutter ‘owner!._debugCurrentBuildTarget == this’: is not true. #87

I had the same issue and the problem was I had called the class inside the same class. See the body: below. Replacing it with another widget fixed the issue.

class DicePage extends StatelessWidget {
      @override
      Widget build(BuildContext context) {
        return MaterialApp(
                   home: Scaffold(
                   backgroundColor: Colors.red,
                   appBar: AppBar(
                             title: Text('Dicee'),
                             backgroundColor: Colors.red,
                           ),
                    body: DicePage(),
      ),
    );
  }
}
