devicePixelRatioOf static method

double devicePixelRatioOf(
  1. BuildContext context
)

Returns devicePixelRatio for the nearest MediaQuery ancestor or throws an exception, if no such ancestor exists.

Use of this method will cause the given context to rebuild any time that the MediaQueryData.devicePixelRatio property of the ancestor MediaQuery changes.

Implementation

static double devicePixelRatioOf(BuildContext context) => _of(context, _MediaQueryAspect.devicePixelRatio).devicePixelRatio;
