Where do you expect auth to come from?

If you're following the Firebase documentation, the getting started page initialized an auth variable as:

// Initialize Firebase Authentication and get a reference to the service
const auth = firebase.auth();

CodePudding user response：

Install @react-native-firebase/auth from

npm install @react-native-firebase/auth

and import

import auth from '@react-native-firebase/auth'
