Custom Form Fields

For email Sign Up/Sign In you can add/remove form fields.

Addition

1. Create a field object(Language Field in our case).

2. Add it to the list of SignUp/SignIn fields.

3. Pass object to Email Config.

Full Code Sample.

 @override
  Widget build(BuildContext context) {
    final languageField = Field()
      ..attribute = 'language'
      ..labelText = 'Language'
      ..validate = RequiredValidator(errorText: 'Language is required');

    final signUpFields = getSignUpFields();
    signUpFields.add(createField(languageField));

    return MaterialApp(
      title: 'Easy Auth',
      debugShowCheckedModeBanner: false,
      home: SignIn(
        themeColor: Colors.deepPurple,
        // Sign in and Sign Up fields are customizable in EmailConfig
        methods: [Email(config: EmailConfig(signUpFields: signUpFields))],
        auth: FirebaseAuth.instance,
        onSuccess: (user, context, fields) {
          showSnackBar(
              'You made the signUp flow in record time. Cheers.', context);
          print('user: $user \n fields: $fields');
        },
      ),
    );
  }

Removal

In case you want to remove some form fields (Say Confirm Password).

1. Get the SignUp/SignIn fields.

2. Pop the last field (Confirm Password Field).

3. Pass it to Email Config.

  Widget build(BuildContext context) {
    final signUpFields = getSignUpFields();
    signUpFields.removeLast();

    return MaterialApp(
      title: 'Easy Auth',
      debugShowCheckedModeBanner: false,
      home: SignIn(
        themeColor: Colors.deepPurple,
        // Sign in and Sign Up fields are customizable in EmailConfig
        methods: [Email(config: EmailConfig(signUpFields: signUpFields))],
        auth: FirebaseAuth.instance,
        onSuccess: (user, context, fields) {
          showSnackBar(
              'You made the signUp flow in record time. Cheers.', context);
          print('user: $user \n fields: $fields');
        },
      ),
    );
  }

Note you will receive the above fields in onSuccess Function as fields param. You can their do some operation like saving to the database.
