From *.flatpak to Flathub

Im creating an App LetsCheck under the Apache 2.0 license.

LetsCheck is a Checkmk client for Android, iOS, Linux, Mac OS-X and Windows written with the Flutter SDK.

I got Github Actions that far to produce linux-x86_64 and linux-arm64 binaries as well as flatpak file for x86_64.

Question: what to do to have that flatpak on Flathub and have both x86_64 and arm64 available.

Many many thanks.

P.s.: This is the most relevant commit to arm64 flutter builds on Github feat: linux-arm64 builder · jochumdev/letscheck@1102188 · GitHub

See the Flathub submission documentation Section overview | Flathub Documentation

Maybe I just need some sleep to figure that out :slight_smile:

After reading the official documentation you might also have a look at my flatpak-flutter project. It is tooling to build for both x86_64 and arm64 on Flathub infra, which isn’t exactly straightforward for a Flutter based app.
