how to get current logged in user firebase code example

Example 1: firebase user name java

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if (user != null) {
    // Name, email address, and profile photo Url
    String name = user.getDisplayName();
    String email = user.getEmail();
    Uri photoUrl = user.getPhotoUrl();

    // Check if user's email is verified
    boolean emailVerified = user.isEmailVerified();

    // The user's ID, unique to the Firebase project. Do NOT use this value to
    // authenticate with your backend server, if you have one. Use
    // FirebaseUser.getIdToken() instead.
    String uid = user.getUid();
}

Example 2: update photoURL firebase

this.$fireAuth.currentUser.updateProfile({
    displayName: '',
    photoURL: '',
    email: ''
  })
  .then((r) => {
    console.log(r)
  })
  .catch((e) => {
  console.log(e)
})
