brightnessOf static method
- BuildContext context
Retrieves the Brightness to use for descendant Material widgets, based
on the value of ThemeData.brightness in the given context.
If no InheritedTheme can be found in the given context, or its brightness
is null, it will fall back to MediaQueryData.platformBrightness.
See also:
- maybeBrightnessOf, which returns null if no valid InheritedTheme or MediaQuery exists.
- ThemeData.brightness, the property that takes precedence over MediaQueryData.platformBrightness for descendant Material widgets.
Implementation
static Brightness brightnessOf(BuildContext context) {
final _InheritedTheme? inheritedTheme =
context.dependOnInheritedWidgetOfExactType<_InheritedTheme>();
return inheritedTheme?.theme.data.brightness ?? MediaQuery.platformBrightnessOf(context);
}
