## What it is
An Android flow layout library that wraps child views (typically tags) across multiple rows and supports single-select and multi-select interactions, commonly used for product tag pickers. Data is injected via a ListView-style adapter, selection is styled with standard state_checked selectors, and selected state survives activity recreation or rotation.

## Use cases
- display a list of tags or labels that wrap onto multiple rows in an Android app
- build a tag picker with single-select or limited multi-select behavior
- create selectable chip groups for product categories or filters
- handle tag click and selection-change callbacks in Android UI
- preserve tag selection state across activity recreation or screen rotation
- pre-select specific tags programmatically and read back the selected set

## When to choose
- you are building a View-based Android app in Java and need a wrap-flow tag layout with selection
- you want checkbox-like tag selection driven purely by drawable state selectors instead of manual code
- you need to cap the number of selectable tags (e.g., single-select or max N)

## When to avoid
- you are starting a new project and need actively maintained dependencies (the project is explicitly unmaintained, last released in 2019)
- you are building with Jetpack Compose, where native FlowRow and selection APIs are preferable
- you need a general-purpose layout manager for RecyclerView rather than a specialized tag-selection widget
