Steps to reproduce

import 'package:flutter/material.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:firebase_auth/firebase_auth.dart' hide EmailAuthProvider;
import 'package:firebase_ui_auth/firebase_ui_auth.dart';
import 'firebase_options.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );

  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      title: 'Sign In Test',
      home: SignInTest(),
    );
  }
}

class SignInTest extends StatelessWidget {
  const SignInTest({super.key});

  @override
  Widget build(BuildContext context) {
    return StreamBuilder<User?>(
      stream: FirebaseAuth.instance.authStateChanges(),
      builder: (context, snapshot) {
        int testValue = 0;
        if (!snapshot.hasData) {
          return SignInScreen(
            providers: [
              EmailAuthProvider(),
            ],
            headerBuilder: (context, constraints, shrinkOffset) {
              testValue = 1;
              return const Padding(
                padding: EdgeInsets.all(20),
                child: Center(
                  child: Text('Header text'),
                ),
              );
            },
          );
        }

        return Scaffold(
          body: Center(
            // Text will be 1 if headerBuilder called, 0 if not.
            child: Text('Value: $testValue'),
          ),
        );
      },
    );
  }
}

Expected Behavior

Expect headerBuilder to be triggered and the resulting widget to be displayed.

Actual Behavior

SignInScreen.headerBuilder is not called, so the header widget specified by the user is not displayed.

Any update on this @russellwheatley, thanks!

Edit: Ah, it hides itself automatically when the width of the screen is larger than 800px
