error "cannot find symbol import com.swmansion.rnscreens.RNScreensPackage;" in task compileDebugJavaWithJavac

Hello, I'm trying to use this package with react-navigation 6.x. I've been struggling because of this issue for weeks, but couldn't find out why this happens. So I am just using the old version, but I also want to know the fundamental solution.

Hi @thoratica,

This seems like a material for an issue rather than a discussion, however I'll try to answer it here.

RNScreenPackage class is used by ReactNative CLI for autolinking & code generation purposes. Seeing this stacktrace indicates that application was not properly linked with the library.

My first recommendation would be the most obvious one: clean your node_modules and build directories. Try running:

rm -fr node_modules yarn.lock android/build
yarn install

in your application directory. In case you're using npm and not yarn, remember to replace the command with one that appropriate for npm: npm install I believe. The same goes for yarn.lock file.

Then try to build your application.

If the issue still appears, please consider filing an issue in the repository or provide some more information on your configuration (a reproduction would be the best).
