📦 Formz Snippets

Clean & Complete Formz Input Generators for Flutter

A curated set of ready-to-use Formz input snippets designed for Flutter & BLoC developers.
This extension eliminates boilerplate and helps you create strongly-typed, reusable, scalable input models for Formz (0.8.0+).

🚀 Features

15+ production-ready Formz input templates
Consistent naming and structure
Strongly typed validation logic
Supports String, Int, Double, Email, Mobile, Date, Enum, JSON, Regex, OTP, and more
Highly reusable patterns for BLoC + Formz apps
All snippets follow FormzInput<T, ErrorType> pattern
Written to avoid constructor issues in newer Formz versions

🧠 Why This Extension?

Formz is powerful — but writing input classes repeatedly is not.
This extension provides everything you need, instantly:

Cleaner forms
Cleaner states
Cleaner Cubits/BLoCs
Cleaner validators
Zero repeating boilerplate

If you use BLoC + Formz, this extension saves hours.

  const NameInput.dirty([String value = '']) : super.dirty(value);

  @override
