## What it is
An Android library that animates a FloatingActionButton morphing into a BottomSheetDialog and back. It implements the MaterialUp filter-concept UI pattern for Android apps.

## Use cases
- animate fab to bottom sheet dialog in android
- morph floating action button into filter panel
- material design filter interface for android app
- expandable bottom sheet triggered by fab
- android fab bottomsheet animation library

## When to choose
- you want the MaterialUp filter-concept animation between a FAB and a bottom sheet
- your Android app uses Java and supports API 15+
- you need a ready-made, customizable morph animation with configurable duration, interpolator, and peek height

## When to avoid
- you build in Kotlin with Jetpack Compose and want modern declarative animations
- you need a general-purpose bottom sheet library rather than FAB-to-sheet morphing
- you require actively maintained dependencies and recent Android SDK support
