Expand description

Complete frames and typed view lifecycle notifications.

The platform updates its view registry before sending a lifecycle method, so the client can immediately query the affected view.

Required Methods§

Source

fn pointer_data_packet(&mut self, packet: PointerDataPacket)

Flutter PlatformDispatcher.onPointerDataPacket.

Source

fn key_data(&mut self, data: KeyData) -> bool

Flutter PlatformDispatcher.onKeyData.

Returns whether the framework handled the event; a host that shares the keyboard with other native components should not propagate a handled one.

Source

fn platform_brightness_changed(&mut self)

Flutter PlatformDispatcher.onPlatformBrightnessChanged: the host’s light or dark preference changed, and Platform::platform_brightness already answers the new one.

Source

fn locales_changed(&mut self)

Flutter PlatformDispatcher.onLocaleChanged: the host’s locale list changed, and Platform::locales already answers the new one.

Source

fn wake(&mut self, elapsed: Duration)

A deadline requested through Platform::wake_at has passed.

elapsed is the platform clock, the same one Frame::elapsed reports. Dart’s event loop runs due Timers itself; here the client advances its own clock.
