Flutter Firebase Authentication Signout activity

On user signout, how to detect signout activity and reload botton navigation bar and pages in flutter with firebase authentication?

Solution

  • I will have to point you to FirebaseAuth.instance.onAuthStateChanged and StreamBuilder. FirebaseAuth.instance.onAuthStateChanged is a stream and will update when the user logs out.

    StreamBuilder<FirebaseUser>(
  stream: FirebaseAuth.instance.onAuthStateChanged,
  builder: (BuildContext context, snapshot) {
    if (snapshot.hasData) {
      return LoggedInWidget()
    } else {
      return LoggedOutWidget();
    }
  },
)
