## What it is
A Google-maintained repository of sample applications showcasing the Kotlin Multiplatform (KMP) Jetpack libraries. Its flagship sample, Fruitties, demonstrates fetching, storing, and displaying data with Multiplatform ViewModel, Room, DataStore, and Ktor across Android and iOS.

## Use cases
- learn how to share code between android and ios using kotlin multiplatform
- example app showing how to use room datastore and ktor in a kmp project
- reference project for kotlin multiplatform viewmodel usage
- sample code for jetpack libraries on kotlin multiplatform
- starting template for building a cross-platform mobile app in kotlin
- see how multiplatform data persistence works in practice

## When to choose
- You want runnable, Google-maintained example code for Kotlin Multiplatform Jetpack libraries like ViewModel, Room, and DataStore
- You are starting a KMP project and need a reference architecture for data fetching, caching, and display
- You want to see how to wire Ktor networking with multiplatform persistence in a real app

## When to avoid
- You need a production library or framework rather than demonstration sample code
- You want step-by-step tutorials or documentation instead of source code examples
- You do not develop in Kotlin or target Android/iOS platforms

## Facets
- artifact type: learning-resource
