## What it is
FreeFlow is a layout engine for Android that decouples layouts from the View containers managing scrolling and view recycling. It enables swappable custom layouts at runtime with smooth transition animations when layouts change.

## Use cases
- create custom grid and list layouts for Android apps
- animate transitions when switching between layouts at runtime
- build sectioned scrolling containers with view recycling
- implement magazine-style or photo-wall layouts on Android
- swap layout styles without rewriting view containers

## When to choose
- maintaining a legacy Android app already built on FreeFlow
- needing runtime-swappable layouts with transition animations on old Android codebases not using RecyclerView

## When to avoid
- starting a new Android project - the project is officially abandoned and the authors recommend RecyclerView
- needing long-term support, bug fixes, or modern Android compatibility
- working with Jetpack Compose or modern Android UI toolkits

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, animation, state-management
- domain: mobile-development, android-tools, web-development
- platform: jvm
- tags: layout-engine, view-recycling, transition-animations, android-viewgroup, custom-layouts, android, mobile
