Does not run on Xubuntu 18.04

Thanks for making an AppImage. As far as I know, this is the first Flutter-based AppImage out there in the wild.

Hoever, it does not run e.g., on Xubuntu 18.04:

me@host:~$ ./Downloads/Otter_Store-x86_64.AppImage 
AppRun	AppRun-x86_64  otter_store.desktop  otter_store.png  usr
/tmp/.mount_Otter_1vVa1t/usr/bin/otter_store: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /tmp/.mount_Otter_1vVa1t/usr/bin/../lib/libgtk-3.so.0)

This happens because the binaries that go into the AppImage have been compiled on a system newer than the system I am trying to run this on (in my case, 18.04). I think it would be worthwhile to have a version that is compatible at least with all still-supported releases of Ubuntu (and other distributions of similar age).

Would it be possible for this to be compiled on Ubuntu xenial (currently the oldest still-supported release), e.g., using Travis CI or GitHub Actions?

Thanks for reporting the problem, I am still new to building AppImages and there are some problems that I am not aware of yet, this is an example.

This is not a first Flutter application in AppImage, I used as a base another project made in flutter to create this AppImage. https://github.com/Wazzaps/karaoke

I will follow your recommendation and soon I will launch a new AppImage
