I am trying to add Firebase Authentication to my app via email and password signup and login. When I test it out, it does not navigate to the next screen and I get the following message:
"Ignoring header X-Firebase-Locale because it was null"
However, when I go to Firebase, it shows the information I entered has been stored as a new user. Could someone please provide some insight on what is going on?
Here is my main.dart:
int? isViewed; Future <void> main() async { WidgetsFlutterBinding.ensureInitialized(); await Firebase.initializeApp(); final prefs = await SharedPreferences.getInstance(); final showLogin = prefs.getBool('showLogin') ?? false; Paint.enableDithering = true; // This is for our onboarding screen isViewed = prefs.getInt('onboard'); runApp(MyApp(showLogin: showLogin)); } class MyApp extends StatelessWidget { final bool showLogin; const MyApp({Key? key, required this.showLogin}) : super(key: key); @override Widget build(BuildContext context) { return MaterialApp( title: 'Strength', debugShowCheckedModeBanner: false, theme: ThemeData( appBarTheme: const AppBarTheme(color: Color(0xffe0eff5), elevation: 0, brightness: Brightness.light, iconTheme: IconThemeData(color: Colors.black), textTheme: TextTheme(headline6: TextStyle(color: Color(0xff888888), fontSize: 18), ) ),), home: const SplashScreen(), ); } } Here are chunks of my signup.dart:
class SignUpScreen extends StatefulWidget { const SignUpScreen({Key? key}) : super(key: key); @override _SignUpScreenState createState() => _SignUpScreenState(); } class _SignUpScreenState extends State<SignUpScreen> { TextEditingController _passwordTextController = TextEditingController(); bool showPassword = false; bool _isPasswordEightLetters = false; bool _OneNumberPassword = false; TextEditingController _emailTextController = TextEditingController(); OnPasswordChanged(String password) { final numericRegex = RegExp(r'[0-9;]'); setState(() { _isPasswordEightLetters = false; if (password.length >= 8) { _isPasswordEightLetters = true; } _OneNumberPassword = false; if(numericRegex.hasMatch(password)) { _OneNumberPassword = true; } }); } . . . Container( child: TextFormField( controller: _emailTextController, style: const TextStyle(color: Colors.black), keyboardType: TextInputType.emailAddress, // inputFormatters: <TextInputFormatter>[ // FilteringTextInputFormatter.allow(RegExp(r'[0-9]')) // ], decoration: InputDecoration( hintText: "Enter Your Email Address", hintStyle: const TextStyle(color: Color(0xff31708c), fontSize: 15.5), prefixIcon: const Icon(Icons.email_sharp, color: Color(0xff31708c)), focusedBorder: OutlineInputBorder( borderRadius: BorderRadius.circular(10), borderSide: const BorderSide(color: Color(0x6630728c))), enabledBorder: OutlineInputBorder( borderRadius: BorderRadius.circular(10), borderSide: const BorderSide(color: Color(0x6630728c), ), ), ), autofillHints: const [AutofillHints.email] ), decoration: BoxDecoration(color: Colors.blueGrey.withOpacity(0.08), borderRadius: BorderRadius.circular(10)), ) . . . ButtonTheme( minWidth: MediaQuery.of(context).size.width, height: 55, buttonColor: const Color(0xff31708c), child: RaisedButton( onPressed: () { FirebaseAuth.instance.createUserWithEmailAndPassword( email: _emailTextController.text, password: _passwordTextController.text).then((_) { print('New Account Created'); Navigator.of(context). pushReplacement(MaterialPageRoute(builder: (context) => Dashboard())); } ).onError((error, stackTrace) { print('Error'); }); }, shape: RoundedRectangleBorder( borderRadius: BorderRadius.circular(20), ), child: const Text("Sign Up", style: TextStyle(color: Colors.white, fontSize: 18, fontWeight: FontWeight.bold), ), ), )
