The following command
xhost local:$USER && docker run --rm -ti -e UID=$(id -u) -e GID=$(id -g) -p 42000:42000 --workdir /project --device /dev/kvm --device /dev/dri:/dev/dri -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY -v "$PWD":/project --entrypoint flutter-android-emulator matspfeiffer/flutter
results in this output:

non-network local connections being added to access control list
The Android emulator exited with code 1 during startup
Android emulator stderr:
Address these issues and try again.
No devices found with name or id matching 'emulator-5554'

flutter doctor shows some issues:

[!] Android Studio (not installed)
[!] Connected device
! No devices available

Are you really using the latest image? Try to remove the image locally and rerun the command. Normally the emulator created by the Flutter CLI is named "flutter_emulator".

When you use VSCode try the remote extensions to run your project in a container. That's a huge improvement. You will find the instructions on my GitHub repository.

I tried with both :latest and :beta.
Here is "flutter doctor" output for :beta image:
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel beta, 1.19.0-4.3.pre, on Linux, locale en_US)
[✓] Android toolchain - develop for Android devices (Android SDK version 28.0.3)
[✗] Chrome - develop for the web (Cannot find Chrome executable at google-chrome)
! Cannot find Chrome. Try setting CHROME_EXECUTABLE to a Chrome executable.
[!] Android Studio (not installed)
[✓] Connected device (1 available)

Do I need to install Android Studio on my host?

Now your output is showing a connected device.

To show all emulators execute "flutter emulators".

To launch it "flutter emulators --launch flutter_emulator".

I actually found the issue you have and will push the fix in a few minutes. It comes from an incomplete refactoring.. Afterwards the right emulator will launch ;-)

I get the following message

The Android emulator exited with code 1 during startup
Android emulator stderr:
Address these issues and try again.

when I run

flutter emulators --launch flutter_emulator

You can also use the -v flag to get more info about the issue or problem that is occurring.
