════════ Exception caught by widgets library ═══════════════════════════════════
The following assertion was thrown building Container(bg: BoxDecoration(gradient: LinearGradient(begin: Alignment.topLeft, end: Alignment.bottomRight, colors: [Color(0xffffd700), Color(0xffffecb3)], tileMode: TileMode.clamp)), constraints: BoxConstraints(biggest)):
dependOnInheritedWidgetOfExactType() or dependOnInheritedElement() was called before _GameScreenState.initState() completed.
When an inherited widget changes, for example if the value of Theme.of() changes, its dependent widgets are rebuilt. If the dependent widget's reference to the inherited widget is in a constructor or an initState() method, then the rebuilt dependent widget will not reflect the changes in the inherited widget.
Typically references to inherited widgets should occur in widget build() methods.  Alternatively, initialization based on inherited widgets can be placed in the didChangeDependencies method, which is called after initState and whenever the dependencies change thereafter.

Однажды я попытался взять весь виджет внутри SafeArea, а затем удалить его, установив высоту с помощью sizebox внутри Expanded, оба не сработали.
Я новичок в Flutter и изучаю его, это один из проектов, над которыми я работаю, есть идеи, что вызывает проблему и как ее исправить
