Hi 😌👋 I do not understand what you were trying to achieve that you'd expect as a result or a feature of this app?

@yuanhoujun Can you share more details, including the snapcraft log, and your expectations?

@Feichtmeier @oSoMoN Thanks for your reply. I'm working on a new Flutter app on Ubuntu. The official website is here: https://cca.yhdm360.cn/. I can generate AppImage binary, and other binaries exclude snap.

I try to use core18 as my base, but audioplayers library depend a newer stdc++ library, so I have to update base to core22 or core20. But there aren't Flutter extension in core20 and core22.

By chance, I found this library, I refer to your configuration of snapcraft. But it's not working, It entered snapcraft shell env.

I'm not very familiar with snap, I hope you guys could help me, I'll very appreciate that.
