Answer 1

Error occurred because of cyclic dependency of react-native pakcage.

Use this repository for solution [a link] (https://github.com/vishalkhoje/cyclicImportReactNative)!

1. Here problem is install react-native-device-info package as dependency into your root project not in your custom package.
2. In your custom package use react-native-device-info adn react-native as a peer dependancy. Ex. This is in your custom package.json file, important is version of package is same as root project package.json file.

"peerDependencies": {
    "react-native": "^0.64.1",
    "@types/react-native": "^0.64.5",
    "react-native-device-info": "^8.1.2"
  }

This will solve your problem.
