Flutter on ARM64 chromebook

[mictadlo]

Steps to reproduce

I found a post here from @christopherfujino that:

Linux Host ARM64 is supported for linux ARM64 and web targets on the latest master channel.

Unfortunately, I do not know how to get it installed. Could you please provide me with any installation steps?

Thank you in advance,

Michal

Actual results

I can't find ARM64 from Flutter SDK

Logs

No response

Flutter Doctor output

I was not able to find Flutter for ARM64

I believe you're talking about the Linux Arm64 Host.

From what I understand, the Flutter SDK can be built from source on Linux Arm64, but the Flutter team doesn't provide pre-built binaries for it. Flutter requires several native binaries/libs to run.

However, you can try building the Flutter SDK from source on your Linux Arm64 machine, or you can use others' pre-built binaries like https://github.com/containerbase/flutter-prebuild, but use it at your own risk.

Hi, Thank you. My Lenove Duet Chromebook might not handle a second layer of virtualization. Is there a reason why Google/Dart/Flutter does not provide ARM64 releases?
I think people with ARM64 Chromebooks and Raspberry PI would like it, too.

Most probably this is similar to the one you are looking for. You will need to follow-up in it for further updates or share your findings in it for better tracking.
Closing this in favor of the linked issue. If you disagree, write in comments and I'll reopen it.

Thanks for linking that issue @darshankawar. I just closed that issue, as we actually do build and upload binaries for linux arm64 hosts, you just can't download a tarball for it from the website. However, if you clone this repository on a linux arm64 machine, the flutter/bin/flutter bash script should ensure that you have all the correct architecture binaries downloaded.

I have done this before on a raspberry pi. I have not kept up to date with linux userspace on ChromeOS, so your mileage may vary there (if you have a mainstream Linux distribution installed such as Ubuntu or Arch, things should "just work").

Thank you, it works. Any suggestions how to improve it?

This is more or less what I would do (although with vim :) ). One option is to use canonical's Flutter snap: https://snapcraft.io/flutter, which I believe would handle sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev, although you'd also have to install and/or configure snap.
