handlePlatformBrightnessChanged method

  1. @protected
void handlePlatformBrightnessChanged()

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.
final Brightness brightness = MediaQuery.platformBrightnessOf(context);

final Brightness brightness = WidgetsBinding.instance.platformDispatcher.platformBrightness;

See dart:ui.PlatformDispatcher.onPlatformBrightnessChanged.
