Validatorless is a Flutter package designed to simplify text input validation, inspired by Yup. It offers a flexible and intuitive way to define validation rules for form fields, enabling developers to create robust input validation logic with minimal boilerplate. The package supports various validation types and can be easily integrated into Flutter applications across multiple platforms. It focuses on clean syntax and extensibility, making it ideal for forms requiring dynamic or complex validation workflows.

Publishing

Pushes to master run .github/workflows/publish.yml: patch-bump pubspec.yaml (unless the push already changed the version), append CHANGELOG.md, commit with [skip ci], tag (1.3.1, no v prefix), create a GitHub Release, and dart pub publish --force.

Add a repository secret named PUB_CREDENTIALS_JSON (Settings → Secrets and variables → Actions) containing the full contents of the Dart credentials file after dart pub login:

Linux: ~/.pub-cache/credentials.json or ~/.config/dart/pub-credentials.json
macOS: ~/Library/Application Support/dart/pub-credentials.json

Do not commit that file. The workflow fails if the secret is missing.
