In a non-expo project, add "@react-native-seoul/masonry-list": "1.4.2", to package.json and run yarn install, see warning:

YN0002: │ @test/mobile@workspace:packages/mobile doesn't provide expo (pb91be), requested by @react-native-seoul/masonry-list

Expected behavior
No warnings should print to console unless expo is being used in the core project itself. Maybe we need
