## What it is
A Flutter package that simplifies building data-collection forms by removing boilerplate for validation, change reactions, and value collection. It ships ready-made input fields like checkboxes, dropdowns, date pickers, and radio groups built on FormBuilderField.

## Use cases
- build forms in flutter with less boilerplate
- validate form fields in a flutter app
- collect user input from a flutter form
- create sign-up or survey forms in flutter
- conditionally validate form inputs in flutter
- add ready-made input fields like dropdowns and date pickers to flutter forms

## When to choose
- you are building Flutter apps for mobile, web, or desktop and need structured forms with validation
- you want prebuilt input field widgets instead of writing custom FormBuilderField widgets
- you need programmatic control over form values, errors, and resets

## When to avoid
- you are not using Flutter/Dart
- you need only a single simple input without form-level validation
- you require a heavily maintained project - the team is actively seeking maintainers
