Flutter Engine Artifact Download Fails (maybe with incorrect file name?)

[JesperBllnbm]

Hi @jwinarske,

I'm encountering an issue with the Flutter engine artifact download in the workspace automation script. This seems to be a continuation of the problem described in issue #24, but with some new details.

Current Behavior: When running the flutter_workspace.py script, the engine artifact download fails with the following error:

...

    ! Flutter version 3.24.0 on channel [user-branch] at /home/<user>/Documents/dev/workspace-automation/flutter
      Currently on an unknown channel. Run `flutter channel` to switch to an official channel.
      If that doesn't fix the issue, reinstall Flutter by following instructions at https://flutter.dev/setup.

      Set environment variable "FLUTTER_GIT_URL" to unknown source to dismiss this error.

Expected Behavior: The script should successfully download the Flutter engine artifact and continue with the setup process.

Possible Cause: The URL being used to download the artifact may be incorrect. It appears that the .zip extension is missing from the URL.

Steps to Reproduce:

1. Clone the workspace-automation repository
2. Run the flutter_workspace.py script
3. Observe the error message about failing to download the engine artifact

Environment:

• OS: Ubuntu 24.04 LTS
• Python version: 3.12
• Flutter version: 3.24.0

Thank you for your help in addressing this issue and for making the world of embedded Flutter more accessible!

@JesperBllnbm I see the issue. Should have a fix in today

[jwinarske]

@JesperBllnbm Looks like they no longer package libflutter_engine.so. So this will have to wait for the flutter-engine repo to come online. They also dropped arm64. It's not clear who the customer is for this new format.

Hi @jwinarske,

I was able to move forward by manually downloading the flutter engine from here: https://github.com/sony/flutter-embedded-linux/releases/tag/b8800d88be

@JesperBllnbm v2.0 branch has been updated to pull engine artifacts from https://github.com/meta-flutter/flutter-engine/
