The code in this repository is designed to streamline the validation process in your Flutter projects. It consists of:
-
Custom Validators: Easily create and combine validators tailored to your needs.
-
Synchronous and Asynchronous Validation: Supports both types of validation, including remote checks and complex operations.
-
Built-in Validators: Includes a variety of common validators like required fields, min/max length, regex pattern matching, and more.
-
Flexible Error Messages: Customize error messages for each validation rule.
To use validify in your Dart or Flutter project, add the following dependency to your pubspec.yaml file:
dependencies:
validify: ^0.0.3Then, run flutter pub get to install the package.
class EmailValidator extends Validify {
@override
List<ValidatorFunction> get validators => [
Validator.require(message: 'Email is required'),
Validator.pattern(r'^[^@]+@[^@]+\.[^@]+$', message: 'Invalid email format'),
];
}
TextFormField(
controller: _emailController,
decoration: const InputDecoration(
labelText: 'Email',
border: OutlineInputBorder(),
),
validator: EmailValidator().validate,
),
/// ------------ or ------------
final ValidatorFunction _passwordValidator = Validators.combine([
Validators.require(message: 'Password is required'),
Validators.minLength(6, message: (length) => 'Password must be at least $length characters long'),
]);
TextFormField(
controller: _passwordController,
obscureText: true,
decoration: const InputDecoration(
labelText: 'Password',
border: OutlineInputBorder(),
),
validator: _passwordValidator,
),A utility class for creating and managing validation rules:
require({String? message}): Validator for checking if a value is not empty.minLength(int length, {String? Function(int)? message}): Validator for minimum length.maxLength(int length, {String? Function(int)? message}): Validator for maximum length.pattern(RegExp pattern, {String? message}): Validator for matching a regex pattern.combine(List<ValidatorFunction> validators): Combines multiple validators.equality(String firstValue, String secondValue, {required String message}): Checks if two values are equal.asyncPattern(RegExp pattern, {String? message}): Asynchronous validator for regex pattern matching.custom({required bool Function(String? value) condition, required String message}): Custom validator based on a condition.trimAndValidate(ValidatorFunction validator): Trims whitespace and then applies the provided validator.dateAfter(DateTime date, {String? message}): Validator for checking if a date is after a specified date.combineAsync(List<AsyncValidatorFunction> validators): Combines multiple asynchronous validators.
-
Reusable: Once set up, you can reuse these validators across different projects.
-
Extensible: Easily extend and customize validators for specific use cases.
-
Clean Code: Encourages clean and maintainable code by abstracting validation logic.
