handlePlatformBrightnessChanged method
override
Called when the platform brightness changes.
The current platform brightness can be queried from a Flutter binding or from a MediaQuery widget. The latter is preferred from widgets because it causes the widget to be automatically rebuilt when the brightness changes.
Querying MediaQuery.platformBrightnessOf directly. Preferred.
link
final Brightness brightness = MediaQuery.platformBrightnessOf(context);
Querying PlatformDispatcher.platformBrightness.
link
final Brightness brightness = WidgetsBinding.instance.platformDispatcher.platformBrightness;
Implementation
@override
void handlePlatformBrightnessChanged() {
super.handlePlatformBrightnessChanged();
for (final WidgetsBindingObserver observer in List<WidgetsBindingObserver>.of(_observers)) {
observer.didChangePlatformBrightness();
}
}
