Welcome to former

former is a form library for Flutter, inspired by formik.

Motivation

Formik is one of my favorite React libraries. It is a form library that drastically reduces boilerplate for keeping track of field values, validation, and form submission.

Form building in Flutter suffers from similar issues:

  • Developers have to manually keep track of field values, for example using TextEditingControllers.
  • Validation and error handling requires imperative logic.

This is where former comes in.

Features

  • Enabling/disabling form globally
  • Declarative form validation
  • Automatic value tracking via Former form controls.
  • Easy error handling with FormerError widget.
  • Type-safe access of form.
