onAccessibilityFeaturesChanged property

VoidCallback? onAccessibilityFeaturesChanged

A callback that is invoked when the value of accessibilityFeatures changes.

Accessing this value returns the value contained in the PlatformDispatcher singleton, so instead of getting it from here, you should consider getting it from WidgetsBinding.instance.platformDispatcher instead (or, when WidgetsBinding isn't available, from PlatformDispatcher.instance). The reason this value forwards to the PlatformDispatcher is to provide convenience for applications that only use a single main window.

The framework invokes this callback in the same zone in which the callback was set.

Implementation

VoidCallback? get onAccessibilityFeaturesChanged => platformDispatcher.onAccessibilityFeaturesChanged;
void onAccessibilityFeaturesChanged=(VoidCallback? callback)

Implementation

set onAccessibilityFeaturesChanged(VoidCallback? callback) {
  platformDispatcher.onAccessibilityFeaturesChanged = callback;
}
