What works for us is using WidgetsBinding.instance.window instead of MediaQuery - also when setting the theme of the MaterialApp:

_pixelRatio = WidgetsBinding.instance.window.devicePixelRatio;
_screenWidth = WidgetsBinding.instance.window.physicalSize.width;
_screenHeight = WidgetsBinding.instance.window.physicalSize.height;
_statusBarHeight = WidgetsBinding.instance.window.padding.top;
_bottomBarHeight = WidgetsBinding.instance.window.padding.bottom;
_textScaleFactor = WidgetsBinding.instance.window.textScaleFactor;
