FlashCard

A Kotlin Multiplatform app (Android and iOS) that shows learning cards in a full-screen vertical pager. The cards are filled with artworks from a public museum collection API.

Context

Built in February 2024 (21 and 22 Feb). The project grew out of the Kotlin Multiplatform "museum" sample (the first data class was renamed from Museum to Question).

What it shows

• One Compose Multiplatform UI in commonMain for both platforms. Each platform has a thin entry point: MainActivity on Android and MainViewController on iOS.
• A vertical, snapping pager for a short-video style feed, and a list screen with overlapping image cards.
• Ktor with kotlinx.serialization for networking, and Kamel for async image loading.
• Koin for dependency injection, Voyager for screen models and navigation, and moko-resources for strings.
• SQLDelight with platform DriverFactory implementations. So far only the tutorial schema is wired in.

Stack

Kotlin 1.9, Compose Multiplatform 1.5, Ktor 2, Koin, Voyager, Kamel, SQLDelight 2, Gradle (version catalog). Android min SDK 24, plus an iOS app.

Run it

Open the project in Android Studio or Fleet with the Kotlin Multiplatform plugin. Run composeApp on Android, or open iosApp in Xcode for iOS.

Looking back (2026)

The local import feature and the database layer never went past scaffolding, and there are no tests. Today I would define the shared domain and a test suite in commonMain before building screens.
