terminal and externalTerminal console configuration should warn that they are not supported for Flutter

Describe the bug: It seems that whenever we set "console": "externalTerminal" or "console": "terminal" in the launch.json for Flutter apps, the configuration is being ignored and the Flutter logs are displayed in the Debug Console, even if you add "dart.cliConsole": "externalTerminal" in the settings.json. It’s working fine for Dart apps, though.

@DanTup, could it be related to https://github.com/Dart-Code/Dart-Code/issues/3434?

To Reproduce:

1. Create a Flutter app
2. Create a launch configuration and set console to terminal or externalTerminal:

{
    "configurations": [
        {
            "name": "Flutter",
            "type": "dart",
            "request": "launch",
            "program": "lib\\main.dart",
            "console": "externalTerminal"
        }
    ]
}

1. The logs will be shown in the Debug Console.

Expected behavior See the Flutter logs in the selected terminal. For me, the most important thing is externalTerminal, since it helps me a lot with my windows placement (vscode | emulator + terminal)

Versions:

• Windows 10
• VS Code version: 1.63.2
• Dart extension version: v3.32.0
• Dart/Flutter SDK version: Dart 2.15.1 | Flutter 2.8.1

Now shows this during launch:

Using "type": "flutter" is a little complicated, as we generally decide whether a project is Flutter or not during the resolution of the debug config (so that you can just press F5 when you have a .dart file open and get the right thing regardless of project type). Having an additional type would also force the user to select between Dart or Flutter if they hit F5 with no files open (whereas now we call dart “Dart & Flutter”).

or something that would alert/inform the user that Flutter doesn’t support terminal/externalTerminal.

That’s valid - it shouldn’t silently ignore it. I’ll use this issue for adding a warning.

Unfortunately, until VS Code supports multiple Windows (which I think lots of people want, but may be blocked on electron) I don’t think there’s a great solution to this. When it does, I would expect you’d be able to detach the Debug Console and put it wherever you’d like though, which probably addresses your need?
