platformBrightnessOf static method
- BuildContext context
Returns MediaQueryData.platformBrightness for the nearest MediaQuery ancestor or Brightness.light, 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.
Prefer using this function over getting the attribute directly from the
MediaQueryData returned from of, because using this function will only
rebuild the context
when this specific attribute changes, not when any
attribute changes.
Implementation
static Brightness platformBrightnessOf(BuildContext context) => maybePlatformBrightnessOf(context) ?? Brightness.light;
