But none of these solved my issue.

I am a beginner in react-native. So I don't know what other details files I need to post here. Do let me know if you need any other files.

Answer 1

For me the following two solved it (I think it was the latter that did it):

1. Reset cache: react-native start --reset-cache
2. Clean Android: cd android -> ./gradlew clean
