Snapcraft build for flutter fails

Hey there,
I am creating a desktop application for linux in flutter.
I want to release it on snap (mostly because flutter provides a little how to and I don't looked for alternatives).
When snapcrafting, I get following exception:

/root/snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org/path_provider_windows-2.0.3/

Verify that the part is using the correct parameters and try again.

is it possible that the exception is thrown because libsecret-1-0 is the name of the ubuntu package and not the arch one? If so, how can I craft the snap on arch than?
I know that there is flutter_secured_storage-linux simlink is mentioned. But if that would be the problem I'd assume that the normal build would'nt work eiter.

Hi there, welcome to the community.

Try installing libsecret

sudo pacman -S libsecret

Hey,
thanks for the answer.
But unfortunately it is already installed, as I needed it to test the app :-/

Wait, this means you explicitly marked libsecret-1 as dependency? I am not really sure but as far as I know, libsecret-1 is for debian based and libsecret is for Arch based.

So, is there any way to mark it as an “alternative” dependency?

After 2 more hours of search I found the "try" command.
If you use "try: -libsecret-1-0 else: -libsecret"
snap will use libsecret as fallbakc if libsecret-1-0 is not found.
Your "alternative" lead me to seach fo rsnap different distro which lead me finally to the advanced grammar section from offical documentation -.-

So, it's solved now I guess.

And btw, it's a new thing you learned. Good for you!
