Interaction with running flutter process exits prematurely on Windows

[jcs090218]

When I try flutter-run, then I got the following error:

More than one device connected; please specify a device with the '-d <deviceId>' flag, or use '-d all' to act on all devices.

<list of devices>

Process Flutter exited abnormally with code 1

Does this package support entering the device id?

When I run flutter-run with multiple devices available, I get a prompt that lets me interactively choose the device:

Checking for wireless devices...

What versions of Flutter and Emacs are you using?

I get a prompt that lets me interactively choose the device:

That's what I was expecting. I get the prompt in the terminal, but not with this package. 🤔

flutter --version:

Flutter 3.10.6 • channel stable • https://github.com/flutter/flutter.git
Framework • revision f468f3366c (4 weeks ago) • 2023-07-12 15:19:05 -0700
Engine • revision cdbeda788a
Tools • Dart 3.0.6 • DevTools 2.23.1

Emacs 29.1 and on Windows 11.

My best guess is that either Flutter or Emacs behaves differently on Windows.

flutter-run starts the flutter process with make-comint-in-buffer. I tried to look into how that works to see if there were any relevant code paths that might explain the difference, but I didn't see any.

At the moment the only workaround is this: #1 (comment)

If you run (flutter-run "-d all") (or -d 1 or whatever), does the app start and can you interact with the flutter process with the usual keys? (r to refresh, etc.)

The app starts! But do we have to define the command ourselves? 🤔 It will be nice if we could just customize the arguments.

can you interact with the flutter process with the usual keys?

Yes, it works! However, it turns out I will get the same result in the first post (Process Flutter exited abnormally with code 1).

You can make your own function and bind it as you like, per the comment I linked earlier.

OK so it sounds like interactivity just doesn't work correctly on your setup. That's the real bug here, so I will keep this ticket open but clarify the title.

For improving the UI for choosing a device, see #1.

I mean, I was hoping for a built-in solution from this package, so I don't have to define it myself.

👍 Thank you for the reply. It's very helpful! :D
