Dartx Validate #

Dartx Validate is a Zod-like validation library for Dart, providing a simple and expressive way to validate data structures.

Features #

• Decorators for easy validation
• Support for complex data structures
• Custom validation logic

Getting Started #

To get started with Dartx Validate, add the following dependency to your pubspec.yaml file:

dependencies:
  dartx_validate: ^1.0.0 # replace with the latest version

Then, import the package in your Dart code:

import 'package:dartx_validate/dartx_validate.dart';

Usage #

To create a schema with Dartx Validate, use the provided decorators. Here's an example of how to validate a simple user object:

import 'package:dartx_validate/dartx_validate.dart';

class User {
  @Email()
  final String email;

  @MinLength(2)
  @MaxLength(100)
  @NotEmpty()
  final String name;

  @Min(0)
  @Max(100)
  final int age;

  @Positive()
  final int id;

  User(this.name, this.email, this.age, this.id);
}

Validation #

To validate an instance of the User class, you can use the validate function provided by Dartx Validate:

import 'package:dartx_validate/dartx_validate.dart';

void main() {
  final user = User('John Doe', '[email protected]', 30, 1);

  if (validate(user)) {
    print("OK");
  }
}

Custom Validators #

To create custom validators, you can extend the base validator class and implement your own logic:

import 'package:dartx_validate/dartx_validate.dart';

class Even extends Validator<int> {
    @override
    bool validate(int value) {
        return value % 2 == 0;
    }

    @override
    String get errorMessage => 'Value must be even';
}

Use your custom Validator #

class NumberHolder {
    @Even()
    final int number;

    NumberHolder(this.number);
}
