LucidValidation

A Dart/Flutter package for building strongly typed validation rules, inspired by FluentValidation. Created by the Flutterando community, this package aims to provide a flexible and powerful way to validate your models in Flutter and Dart projects.

Features

Strongly typed validation rules.
Fluent API for defining validations.
Extensible with custom validators.
Easy to integrate with any Dart or Flutter project.

Example

import 'package:lucid_validation/lucid_validation.dart';

class UserModel {
  String email;
  String password;
  int age;
  String phone;

  UserModel({
    required this.email,
    required this.password,
    required this.age,
    required this.phone,
  });

  factory UserModel.empty() => UserModel(email: '', password: '', age: 18, phone: '');
}

class UserValidation extends LucidValidation<UserModel> {
  UserValidation() {
    ruleFor((user) => user.email, key: 'email')
        .notEmpty()
        .validEmail();

    ruleFor((user) => user.password, key: 'password')
        .customValidPassword();

    ruleFor((user) => user.age, key: 'age')
        .min(18, message: 'Minimum age is 18 years');

    ruleFor((user) => user.phone, key: 'phone')
        .customValidPhone('Phone invalid format');
  }
}
