How Mobile Apps Use Reactive UI With Kotlin Flow

In this episode, Lucas and Luna explore how Android developers are using Kotlin Flow for reactive UI patterns in 2026. They break down a real example: a food delivery app that eliminated manual state refreshing by using Flow to observe live order status changes. Lucas explains the difference between StateFlow and SharedFlow, and why cold flows matter for database queries. Luna shares how iOS developers are now bringing similar patterns to Swift with AsyncSequence. The hosts also discuss how reactive UI reduces boilerplate, improves battery life by stopping unnecessary recompositions, and changes how developers think about data pipelines. If you're building mobile apps and want cleaner state management, this episode gives you a concrete pattern you can start using today. #KotlinFlow #ReactiveUI #StateFlow #SharedFlow #AndroidDev #SwiftAsyncSequence #MobileApps #UIStateManagement #FoodDeliveryApp #LiveOrderTracking #ColdFlow #HotFlow #JetpackCompose #SwiftUI #Technology #MobileDevelopment #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
