Unable to set FirebaseUser photoUrl to null

Question

What I'm trying to do

I'm trying to delete user image (by setting photoUrl = null). Here is my code:

    final UserUpdateInfo updatedInfo = UserUpdateInfo();
    updatedInfo.photoUrl = null;
    print(updatedInfo.photoUrl);
    final user = await _auth.currentUser();
    print('Before update: ${user.photoUrl}');
    await user.updateProfile(updatedInfo);
    await user.reload();
    final newUser = await FirebaseAuth.instance.currentUser();
    print('After update: ${newUser.photoUrl}');

Expected Output: The expected out is to get null from newUser.photoUrl.

Actual Output

I/flutter (10813): null
I/flutter (10813): Before update: test20, https://firebasestorage.googleapis.com/v0/b/****/o/profileImages%2FIMG_20200129_133820.jpg?alt=media&token=6597dd66-e3b3-4b87-84b4-9000ceea54b4

Don't know what is the actual issue. The same code works if I'm updating the photoUrl with a new url but doesn't work while setting it to null.

I had the same issue.

You have to set:

{ photoURL: '' }

instead of null. I think it is a bug.
