sendKeyUpEvent method Null safety
- LogicalKeyboardKey key,
- {String platform = _defaultPlatform,
- PhysicalKeyboardKey? physicalKey}
Simulates sending a physical key up event through the system channel.
This only simulates key up events coming from a physical keyboard, not from a soft keyboard.
Specify platform as one of the platforms allowed in
platform.Platform.operatingSystem to make the event appear to be from
that type of system. Defaults to "web" on web, and "android" everywhere
else. May not be null.
Specify the physicalKey for the event to override what is included in
the simulated event. If not specified, it uses a default from the US
keyboard layout for the corresponding logical key.
Whether the event is sent through RawKeyEvent or KeyEvent is controlled by debugKeyEventSimulatorTransitModeOverride.
Returns true if the key event was handled by the framework.
See also:
- sendKeyDownEvent and sendKeyRepeatEvent to simulate the corresponding key down and repeat event.
- sendKeyEvent to simulate both the key up and key down in the same call.
Implementation
Future<bool> sendKeyUpEvent(
LogicalKeyboardKey key, {
String platform = _defaultPlatform,
PhysicalKeyboardKey? physicalKey
}) async {
assert(platform != null);
// Internally wrapped in async guard.
return simulateKeyUpEvent(key, platform: platform, physicalKey: physicalKey);
}
