Flutter ETS API Documentation v1.0.0
Class: StatusBarClickChannel
System channel that notifies the Flutter framework when the OpenHarmony status bar is tapped.
FlutterView registers for usual.event.CLICK_STATUSBAR
via common-event subscription; when an event is delivered, sendClick() invokes handleScrollToTop on the Dart
side over channel flutter/status_bar (typically scroll-to-top / primary scroll reset behavior).
Constructors
Constructor
new StatusBarClickChannel(
binaryMessenger):StatusBarClickChannel
Creates the channel on the given Dart isolate messenger.
Parameters
binaryMessenger
Binary messenger from the Dart executor used to send platform messages to Flutter.
Returns
StatusBarClickChannel
Methods
sendClick()
sendClick():
void
Sends a status-bar click notification to Flutter by invoking handleScrollToTop on flutter/status_bar.
Call when the embedding has received a confirmed status-bar click from the system common-event pipeline (for example
after FlutterView.onStatusBarClick completes subscription and events arrive). Flutter handles the method on the
framework side; invoke from the appropriate runner/thread context for your embedding.
Returns
void
