Doesn't work as non-root user

[parched]

I'm trying to use this in gitpod, where there is a non-root user, but it fails with

Flutter failed to open a file at "/sdks/flutter/bin/cache/lockfile". The flutter tool cannot access the file.
Please ensure that the SDK and/or project is installed in a location that has read/write permissions for the current user.

I just added

RUN chmod -R a+w $FLUTTER_HOME

to fix it, but I'm not sure if there is a better solution.

Could you please provide a bit more details about gitpod and how it's configured for you?

Gitpod is a cloud IDE which gives you a shell in a docker instance. You can specify the Dockerfile, e.g., I'm trying this one. The user it gives you is not the root user, but gitpod.

You can try it here if you like

I think it's a question for the GitPod folks. If you can use a custom Dockerfile then you probably can try the following one:

FROM cirrusci/flutter:stable

USER gitpod
RUN chmod -R a+w $FLUTTER_HOME

🤷

I have a similar issue. I am trying to use this image with dagger.io.
It works well if I run my commands as root, but I get a warning from flutter saying that I shouldn't
Running it as a different user doesn't work
I got the same error around the lockfile, if I remove it I get
Flutter failed to check for directory existence at "/root/.pub-cache/hosted/pub.dartlang.org/_fe_analyzer_shared-31.0.0/lib/". instead

Maybe I shouldn't use this image, but wanted to let it be known at least

I have the same mistake when I launch pipeline not from root

* What went wrong:
Could not determine the dependencies of task ':app:lintVitalReportStagingRelease'.
> Failed to install the following SDK components:

  The SDK directory is not writable (/opt/android-sdk-linux)

If I can suggest a different image, I created a repo for Flutter images that uses non-root use by default. It was also to solve other issues like preaching Android SDK, etc. After trying many existing images like this repository and others, I couldn't find one to fit my needs. @8thgencore, give it a try if you can. It would be nice if some of the things I did could be contributed to this repo, but I wanted to try a different approach, so I created a separate repo.

I just added

RUN chmod -R a+w $FLUTTER_HOME

to fix it, but I'm not sure if there is a better solution.

I'm using the following approach:

RUN chown -R $MY_USER:$MY_USER $FLUTTER_HOME
