Simple and extensible data schema validation.

schemani

Simple and extensible data schema validation for Dart and Flutter. If you know Yup and Laravel Validation you will feel like home using this package.

Please note that the schemani/formini packages are under development. There are still some issues to resolve before this has any help for real use cases. #roadmap

Usage

import 'package:schemani/schemani.dart';

main() {
  const userSchema = MapSchema({
    'name': [Required()],
    'email': [Required(), Email()],
  });

  try {
    userSchema.validate({
      'name': null,
      'email': 'foo example.org',
    });
  } on MapValidationException catch (e) {
    e.exceptions.forEach((field, exception) {
      print('$field => $exception');
    });
  }
}

Will throw MapValidationException only once combining the inner ValidationExceptions.

flutter: name => Required field
flutter: email => Invalid email address

Usage with formini

Use schemani_formini package for validating formini values using schemas. Or just copy the one simple file to your project.

Roadmap

• ListSchema
• Rules
  • References to another fields inside a rule
  • More basic rules (min, max, between, url, etc...)
• i18n ValidationException.toString()
• Benchmarking
