Can't use Backspace when using Terminal mode for Debugging

• VSCode Version: 1.41.1
• OS Version: Windows 10 Pro 64-bit (10.0, Build 18362)

Steps to Reproduce:

1. create launch.json
2. write "console": "terminal" in your configurations
3. write the following code that take an input from user :

import 'dart:io';

main() {
  stdout.writeln('what is Your Name ?');
  String name = stdin.readLineSync();
  print('Welcome $name');
}

1. start debugging

then i can input value , but i can’t use backspace key to undo the text while i write in console.

@gogoIsComing ah, thanks! It may be an extension issue, but the sample code fails in the same way and I can’t see a way in the API for us to handle it. I’ll keep this open while waiting for a response though. Thanks!

This happens even using the VS Code “local echo” sample code in the docs, and it’s not clear whether it’s fixable in the extension. I’ve opened https://github.com/microsoft/vscode/issues/90618.

Re-opening this issue because it seems a certain bug, and it’s not clear if we need to do work here yet.
