Provide A Flatpak Bundle of Syanpse

[Saroufim]

It would be nice to have Synapse as a flatpak bundle to install on all distributions.

Thanks for the request :) I dont have any experience building flatpak bundles, and very little experience using flatpak. I will try give this a look when I have the time but in the meanwhile may I suggest you also take a look at trying it out yourself ;)

+1 to this. I'm unable to use it as is not available for Arch.

Unfortunately, building a flatpak looks quite complicated (just looked at some manifest examples for inspiration). Will try give it a go again when reading the docs but help is very much appreciated if someone can give a hand :)

I wish I could but I'm not a developer, just a user :(

What about a snap package? Is there anything more we gain from flatpak that cannot be handled by snaps?

I got started on one but I am running into compiler errors for some reason...

This is the error I get:

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

I'm not sure why this is happening. I am able to build by running make outside the snap, but somehow running it from the snap gives the above error.
