Invariant Violation: "main" has not been registered. This can happen if:
* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
* A module failed to load due to an error and `AppRegistry.registerComponent` wasn't called.

Sửa bằng cách sau:

Thay key script và main trong file package.json thành

  "main": "./node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "eject": "expo eject",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "test": "jest"
    }

Xóa react-native-scripts trong devDependencies đi.
