1 year ago Hi! Thanks for brining this up. I probably should've clarified that part in the guide. There are two things to note here:
To run Dart-only tests, always run cargo build -r beforehand. This is your issue here; you are missing the binaries locally. If you look in my Dart unit test source code, you will see that it references the binaries in the /target/release folder (or something like that), which doesn't exist (or might be out of date) unless you run cargo build -r right before running the Dart tests.
To run Flutter-specific tests, you will need to create the platform specific binaries, which is what you are mentioning. That can be done through melos run build (for all platform binaries, only possible on macOS, and takes ages to finish) or melos run build:other (windows/linux) or melos run build:android (android). Please note that after you run that build command, you will need to copy the binaries over to the correct part of your /packages/flutter_library_name directory. That is detailed here.

Hi, I'm trying to use mimir to better understand the guide you wrote for flutter_rust_bridge.
I am facing an issue which I can replicate with mimir:
As you can see, this test fails because the shared library cannot be found.
According to the guide you wrote, the shared library binaries are distributed through GitHub Releases, so I did not build them before running the tests. If I do build the shared library however, the result is similar:
