Steps to reproduce

Context
I'm trying to use the widget SignOutButton firebase_ui_auth-1.15.0 to sign out a signed-in user.
The sign-in is done with the SignInScreen from the same package.
My sign-in screen is configured with

    FirebaseUIAuth.configureProviders([
      EmailAuthProvider(),
      GoogleProvider(clientId: "<client_id>")
    ]);

When the user hits the SignOutButton, 3 things can happen:

• the user is on a computer: they get signed-out, without any issues
• the user is on a phone but use the Desktop site option: they're signed-out without any issues
• the user is on a phone and doesn't use the Desktop site option, nothing happens at all.

For info, the button is defined as

SignOutButton(auth: FirebaseAuth.instance,)

I checked the logs and I'm seeing the following error in the console:
Null check operator used on a null value

I tried debugging a bit by reproducing the calls that the SignOutButton does but the farthest I could get is seeing a LateInitializationError.

Expected Behavior

The user is signed out.

Actual Behavior

The user is not signed out and an exception is thrown
