Hi @selvam920 Can you be more specific on Steps to reproduce of this? (which key did you press? and which key is logged actually?...).

Can this sample code reproduce the issue?

Sample code

```dart import 'package:flutter/material.dart'; import 'package:flutter/services.dart'; void main() { runApp( const MaterialApp( home: MyWidget(), ), ); RawKeyboard.instance.addListener((event) { final key = event.logicalKey.keyLabel; print('$key - ${event.runtimeType}'); }); } class MyWidget extends StatelessWidget { const MyWidget({super.key}); @override Widget build(BuildContext context) { return const Scaffold( body: Center( child: Text( 'Build some widgets!', ), ), ); } } ```

Also, please retry on the latest master channel to check if the issue is fixed or not. (since I don't have a such device, I can't verify this).

Thanks, but when I run your sample code, then press key arrow left, enter, ctrl c and I can see it's printed on the console log output. I'm not sure how to reproduce the issue.

Can you also share the Steps to reproduce along with clear Actual result and Expected result?

I pressed control key, in debug the keypressed with num lock. Did you test in Chromebook?

[huycozy]

I don't have Chromebook device, I checked it on Android with a connected physical keyboard.

As I can see from your screenshot above, it seems there are two keys pressed (Control Left and Num Lock), right? And the issue is that Num Lock is printed even you have not pressed it, right?

From my end, when I press Control Left, the output from the console is:

Can you share the log printed when pressing Control Left?
