Build a Multiplatform Image Picker in Kotlin (Android + Web + Desktop) | KMP Full Guide
This project demonstrates how to implement a fully functional Multiplatform Image Picker using Kotlin Multiplatform and Compose Multiplatform.
The goal is to build a reusable image selection component that works seamlessly across:
Android
Web
Desktop (JVM)
Instead of duplicating logic across platforms, this implementation leverages shared common code and the expect/actual pattern to keep the architecture clean, scalable, and production-ready.
What This Video Covers
Designing a shared ImagePicker contract in commonMain
Using expect/actual for platform-specific implementations
Implementing image selection on Android
Handling file input on Web
Integrating a file chooser for Desktop
Structuring a maintainable Kotlin Multiplatform project
This approach ensures that UI logic remains shared while platform-specific behavior is cleanly separated.
