[Help] Compatiblity with Apple M1 ?

[ruizalexandre]

Do you have a solution to run this docker image on Apple M1 ? :)

I know, it's not direct a problem of your image. But I'd like to know if you have a simple solution ☺️

Thanks.

So far I stumbled upon an issue that Android emulators are not supported on Linux ARM. And when I worked around some issue I stumbled on https://github.com/741g/android-emulator-m1-preview/issues/14.

Seems we'll need to wait until emulators are officially supported on ARM Linux and can be installed via sdkmanager emulator

[ruizalexandre]

Perfect ! Thank you for your work and your time !! 🚀

I saw there is now an official emulator here: https://github.com/google/android-emulator-m1-preview

And in the readme it says in big text:

Note: No longer needed Support for downloading the M1-based emulator was added to SDK Manager, so it's not necessary to go to the Github > releases page to download a standalone .app anymore. In AVD Manager go to the Other Images tab as by default it doesn't show the ARM64 images.

Is there still anything blocking now?

cc @fkorotkov @ruizalexandre @ened @westy92 is there any chance for an update?

[fkorotkov]

The problem there is that M1 emulators won't work since we need the emulators for Arm Linux since the Docker images is based of linux. I haven't seen any updates around Arm Linux emulators unfortunetly.

Thanks @fkorotkov - I see now. We will just have to wait then.

Hello, there have been updates on this point?

In my case I would only like to have the arm64 version of the image, so that trivial static analysis operations don't fail because of QEMU exceptions.

[shlomo-shalev]

I get ״qemu: uncaught target signal 6 (Aborted) - core dumped״.

I even tried to build the cirrusci/android-sdk:30 and cirrusci/android-sdk:tools images myself and then build a flutter image but I still had to use --platform linux/amd64 because without that I would get "qemu-x86_64: Could not open '/lib64/ld-linux-x86-64.so.2': No such file or directory" then I built with --platform linux/amd64 and it gave me again "qemu: uncaught target signal 6 (Aborted) - core dumped ".

Unfortunately without it I can't do any flutter command like "flutter build ..." with docker, Any news on this?

I found a workaround by manually install Flutter Linux:

FROM ubuntu:latest

RUN apt-get update && \
    apt-get install -y curl git wget unzip
RUN git clone --depth=1 --branch=stable https://github.com/flutter/flutter.git /usr/local/flutter
ENV PATH="/usr/local/flutter/bin:/usr/local/flutter/bin/cache/dart-sdk/bin:${PATH}"
RUN flutter channel stable && flutter upgrade
# Thus Flutter is installed

The problem is not with installation flutter into image. Run flutter command creates error. Try after installation run "flutter build ..." or after starting container run "flutter start ..."

[yikerman]

@shlomo-shalev In my case I built web in the container using

RUN flutter build web --release

And it succeeded.

At macbook m1???

Yes. However I haven't tried other platforms like linux.

On a side note, for Apple Silicon devices you can try using our Tart virtualization. Our Xcode VM images are much larger than Docker images but they contain everything for building Flutter applications:

brew install cirruslabs/cli/tart
tart clone ghcr.io/cirruslabs/macos-ventura-xcode:latest ventura-xcode
tart run ventura-xcode

Building an amd64 container on Apple Silicon doesn't work, but if you're building an arm64 container then it will work. I'm not sure about android/web, but it works for building Linux Desktop (only arm64). Unfortunately, Flutter don't support building amd64 on arm64 or vice-versa so I gave up on this and finally went with this example (Doesn't work on Apple Silicon but I needed it mainly for a GitHub action). Here is the working Dockerfile of what I previously did if anyone is interested.

flutter doctor works on Linux arm64 (I've tested), I'd love to know if android and web builds work as well if anyone tests this out.

I don't understand why flutter doctor fails on an amd64 container built on arm64. Can someone explain this? Is it a bug with Flutter?
