Original: Shrinking Your Flutter App: Dynamic Asset & Feature Delivery on Android with Play

Short summary

Flutter developers can reduce base APK size by using Google Play Asset Delivery for large media and Play Feature Delivery for optional feature modules, offloading 297 MB SDKs and 60 MB assets to on-demand downloads. Google research shows conversion drops per 6 MB of added APK size, making this approach critical for user acquisition. Implementation uses Gradle asset-pack plugin and a clean Dart wrapper for cross-platform asset management.

  • Google Play Asset Delivery and Feature Delivery decouple app components from base install
  • Conversion rate declines measurably (~6 MB per drop) — size optimization directly impacts user acquisition
  • Practical Dart/Gradle implementation with code patterns for progress tracking and platform abstraction
