Hello! I was trying to build example with CustomCropper and have build error when targeting device:

Bug or other ndk needed? Thank you.

Hi!

The logs indicate that the error is coming from /snap/flutter/current/usr/include/c++/9/memory:121:25, not from croppy itself. After checking the snap repo for Flutter, found this https://github.com/canonical/flutter-snap/issues/83, but without any solutions as of yet.

I'll link this issue there.

A possible solution might be to try to install Flutter via git, not through snap (as indicated in https://github.com/rive-app/rive-flutter/issues/323#issuecomment-1710148004)

@kekland Thank you for your help! Solved by: manually installing flutter
