Can't publish my linux Flutter app on snapcraft

Question

I created a Linux app using flutter & when i tried to publish the app on the snapcraft following the steps on:

https://docs.flutter.dev/deployment/linux

I get error: Failed to load extension 'flutter-master': this extension does not support the 'core20' base.

I tried to change to change the flutter branch to dev and change the core base to (18 - 22) the problem always the same this extension not support this core.

Answer 1
