flutter_formy_base_validators library

A library that defines FormyValidator, FormyCrossValidator and various field-level validators for validating data in FieldControllers.

This library provides a comprehensive set of validation rules for strings, numbers, dates and cross-field scenarios. It enables the creation of dynamic, reactive and highly customizable forms by listening to changes in controllers and automatically triggering rebuilds when the state updates.

Features

• Generic validators (length, contains, required, etc.)
• Numeric validators (min, max, divisible, odd/even, etc.)
• Date validators (before, after, between dates, age checks)
• String pattern validators (email, URL, IP, regex, etc.)
• Cross-field validators (must match, bigger than another field, etc.)

Part of the flutter_formy package.
