Platform Support

Installation

• Add it as a dependency in their pubspec.yaml:

1. Add the latest version of package to your pubspec.yaml (and rundart pub get):

       dependencies:
         string_validator_plus: ^0.0.4
   

2. Import the package and use it in your Flutter App.

       import 'package:string_validator_plus/string_validator_plus.dart';
   

Example

  final registrationFormKey = GlobalKey<FormState>();
  TextEditingController _email = TextEditingController();
  
  Form(
          key: loginUserFormKey,
          child: TextFormField(
            autovalidateMode: AutovalidateMode.onUserInteraction,
            controller: _email,
            validator: validateEmail,
            onChanged: (value) {
              setState(() {
                _email = value;
              });
            },
          ),
        ),      
            

• You just need to specify the type of validation you need, and you don't need to write much code.

  // Example of using string extensions
  String myString = "flutter toolbox+";
  String titleCaseString = myString.toTitleCase();
  
  if (kDebugMode) {
    print(titleCaseString);
  } 
  // Output: "Flutter Toolbox+"
        

• If you want to use an extension, you just have to add it after your string.
