[web] when I pressed 'caps lock' button in MacBook keyboard,
I saw almost same problem today in chrome(web).
ASK: This issue is clear at this time in flutter for web?
CODE:
body: RawKeyboardListener(
focusNode: textNode,
onKey: (RawKeyEvent rawKeyEvent) {
try {
bool keyDown = false; bool keyUp = false;
if (rawKeyEvent.runtimeType == RawKeyDownEvent) keyDown = true;
if (rawKeyEvent.runtimeType == RawKeyUpEvent) keyUp = true;
if (keyUp) {
logger.fine('keyDown=$keyDown, keyUp=$keyUp, rawKeyEvent=${rawKeyEvent.logicalKey.debugName}');
if (rawKeyEvent.logicalKey.keyId == LogicalKeyboardKey.backspace.keyId) {
logger.fine('keyId=${rawKeyEvent.logicalKey.keyId}');
}
}
}
catch (exc) {
logger.warning('RawKeyboardListener.onKey: (RawKeyEvent): exc=$exc');
}
},
child: Container(
child: Text('raw keyboard listener enabled')
),
),
