maybePlatformBrightnessOf static method
- BuildContext context
Returns platformBrightness for the nearest MediaQuery ancestor or null, if no such ancestor exists.
Use of this method will cause the given context
to rebuild any time that
the MediaQueryData.platformBrightness property of the ancestor
MediaQuery changes.
Implementation
static Brightness? maybePlatformBrightnessOf(BuildContext context) => _maybeOf(context, _MediaQueryAspect.platformBrightness)?.platformBrightness;
