## What it is
A collection of Flutter widgets developed by Google but outside the core Flutter team, including scrollable_positioned_list, visibility_detector, linked_scroll_controller, flutter_simple_treeview, and self_storing_input. The original flutter_widgets package has been split into smaller packages and is no longer updated, though individual packages remain available.

## Use cases
- scroll a list to a specific item programmatically in flutter
- detect when a widget becomes visible on screen
- sync two scroll views together
- display a tree structure in flutter
- auto-save form input values to a data store

## When to choose
- you need programmatic scrolling to items in a long list
- you need visibility callbacks for child widgets
- you want Google-authored widget packages for Flutter

## When to avoid
- you want the monolithic flutter_widgets package, which is Dart 3 incompatible and no longer updated
- you need guaranteed support, as it is best-effort and not endorsed by Google

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, state-management
- domain: mobile-development, frontend, cross-platform
- platform: cross-platform
- tags: flutter, dart, widgets, scrolling, visibility-detector, tree-view, mobile, android, ios
