forms-and-input
Enforces Form + GlobalKey<FormState> with TextFormField whose sync validator returns a localized String? (never a hardcoded literal), AutovalidateMode.onUserInteraction, async availability checks moved OUT of the sync validator into a debounced Riverpod Notifier that surfaces errors through state, FocusNode/TextInputAction/onFieldSubmitted traversal, keyboardType/textCapitalization/autofillHints/TextInputFormatter, mandatory TextEditingController/FocusNode disposal, submit-enabled derived from validity (not stored), and scoped rebuilds so a keystroke never rebuilds the whole form. Use when building a Form, TextFormField, or FormField; wiring sync or async validation; managing FocusNode, focus traversal, autofocus, TextInputAction, onFieldSubmitted, or onEditingComplete; setting keyboardType, autofillHints, textCapitalization, or InputFormatter; disposing TextEditingController/FocusNode; enabling/disabling a submit button; or handling keyboard-avoidance on submit.

With your agent
Install OMGSkills skill "zakariaf/flutter-skills:skills/forms-and-input" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/zakariaf/Flutter-Skills /tmp/Flutter-Skills && ln -s /tmp/Flutter-Skills/skills/forms-and-input ~/.claude/skills/forms-and-inputFrom README
Forms and input Text input is where most disposal leaks, un-localized strings, and jank enter a Flutter app. A form is a small state machine: fields hold text, a FormState validates them, and a ViewModel owns anything that touches the network or the clock. Keep those three responsibilities separate. Read the reference for the task at hand: references/validation-sync-and-async.md — sync validator returning localized String?, AutovalidateMode choice, and the debounced-async-in-a-Notifier pattern (why async must NOT live in the sync validator). references/focus-and-keyboard.md — FocusNode lifecycle, traversal order, autofocus, FocusTraversalGroup, TextInputAction, onFieldSubmitted/onEditingComplete, keyboardType, autofillHints, TextInputFormatter, keyboard-avoidance. Run scripts/checkforms.sh before a PR. Non-negotiable rules Every TextEditingController and FocusNode created in a State is disposed in dispose().
