Device pixel ratio without the BuildContext-CodePudding

I need to make resolution resolution-aware images (BitmapDescriptor)


static Future<BitmapDescriptor> makeBitmapDescriptor(
      String path, BuildContext context) {
    return BitmapDescriptor.fromAssetImage(
      ImageConfiguration(devicePixelRatio: MediaQuery.of(context).devicePixelRatio,
      path,
    );
  }

& for that I need the devicePixelRatio, is there a way to get it without the BuildContext & MediaQuery.of(context).devicePixelRatio ?

CodePudding user response：

You can use fromWindow like this:

MediaQueryData.fromWindow(WidgetsBinding.instance.window).devicePixelRatio;
