The bindings generator takes the crate as third party from a local absolute path
So it cannot be reproduced in other device by default
Or we have to manually upload the crate to git
and import the crate from git

Details

Ideally we can copy the whole rust crate and make the flutter_rust_bridge generate the bindings from this rust crate
so we don't have to have the third party dependencies

Acceptance criteria

• the flutter bindings can be used cross the devices without worried about the path

Next steps (optional)

• update https://github.com/zkmopro/flutter-app and https://github.com/zkmopro/mopro_flutter_pacakge
