maybeBrightnessOf static method

Brightness? maybeBrightnessOf(BuildContext context)

Retrieves the Brightness to use for descendant macOS widgets, based on the value of MacosThemeData.brightness in the given context.

If no MacosTheme can be found in the given context, it will fall back to MediaQueryData.platformBrightness.

Returns null if no valid MacosTheme or MediaQuery widgets exist in the ancestry tree.

See also:

• MacosThemeData.brightness, the property takes precedence over MediaQueryData.platformBrightness for descendant macOS widgets.
• brightnessOf, which throws if no valid MacosTheme or MediaQuery exists, instead of returning null.

Implementation

static Brightness? maybeBrightnessOf(BuildContext context) {
  final _InheritedMacosTheme? inheritedTheme =
      context.dependOnInheritedWidgetOfExactType<_InheritedMacosTheme>();
  return inheritedTheme?.theme.data.brightness ??
      MediaQuery.maybeOf(context)?.platformBrightness;
}
