Issue: "flutter attach" fails for web: "_createDevFS: (-32601) Unknown method "_createDevFS"

### Steps to reproduce

If I start an application from one terminal using `flutter run -d windows` and then in another terminal I use `flutter attach --machine` to attach to it, I see no errors and `flutter attach` correctly outputs an `app.started` event. This event is what VS Code/DAP use to communicate with Flutter when attaching.

If I repeat the same steps but using the Chrome device, then I see an error "_createDevFS: (-32601) Unknown method "_createDevFS" and no `app.started` event is emitted, instead you get an "app.stop" with an error (note: you can repro this without the `--machine` and you'll just see the message written to the console, but it's less obvious what the IDE is setting).

The full stack looks like:

```

```

I'm not certain if using `attach` like this is supported, though it's how some of the integration tests work (and I'd expect behaviour to be similar between web/VM).

### Expected results

Attaching to Chrome should behave the same as attaching to a VM.

### Actual results

Attaching to Chrome fails with an error.

### Code sample

This can be reproduced just using a simple `flutter create` app.
