Hello everyone! I am developing a flutter application for desktop and I need to publish it on Snap Store, but recently I faced with a problem.
There is a pubspec file with next dependencies: window_manager and tray_manager.
When I run flutter build linux --release --verbose it’s always fail. Experimentally I determined that compiling crashes on the tray_manager dependency, but without one all is fine.
Error message like this:

After that I found the same issue on Snapcraft repository, but this issue still not resolved.
When I manually install Flutter, there are no compilation errors, but in that case, the Flutter snapcraft plugin becomes meaningless (and changes the snapcraft.yaml file), as similar build issues can occur with absolutely any library. Sometimes I am must use certain libraries for my application, and such errors are very frustrating
I would like to know why it happens and how to avoid it in the future?
