But maintaining two separate implementations, two data flows, and two update mechanisms? That’s a headache. In this session, we’ll explore how Kotlin Multiplatform (KMP) can unify your widget logic across platforms, letting you share state, data, and update code while keeping native UIs through Glance (Android) and WidgetKit (iOS). You’ll learn how to architect a shared KMP core that powers both widgets and apps, manage reactive updates via Flows, and handle background refresh with minimal duplication. A live demo will show a single shared Kotlin module driving widgets on Android and iOS — proving that even the smallest UI can benefit from shared logic.
