Is there an existing issue for this?

Steps to reproduce

I am developing Flutter Web and getting a 'hardware_keyboard' error when I continuously input Korean characters in a TextField. This is a very old issue. Is there a way to fix this problem?

Expected results

When typing Korean characters in a TextField, the expected result is that the characters are inputted correctly and without any errors or crashes. The TextField should function as intended and the app should respond accordingly to the input.

Actual results

The 'hardware_keyboard' error occurs when typing Korean characters in a TextField, especially when typing continuously or rapidly. This error can cause the app to crash or behave unexpectedly.

Code sample

Code sample 
[   return Scaffold(
      body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              SizedBox(
                width: 300.0,
                child: TextField(),
              )
            ],
          )
      ),

    );]
