Building Roblox Reward Apps with Flutter and React Native: The Perkox SDK
Building Roblox Reward Apps with Flutter and React Native
Most Roblox reward apps are cross-platform – and Perkox is the only offerwall platform with native Flutter and React Native SDKs. This guide covers the technical stack.
Why Cross-Platform
Reward apps target both stores. Flutter and React Native deliver both from one codebase. Native offerwall SDKs (not WebViews) mean instant loading and reliable rewards – critical for young audiences with short attention spans.
Flutter Integration
MethodChannel pattern: Dart service → Kotlin/Swift handlers → Perkox SDK. One channel name across all three layers. Reward callbacks flow back through the channel.
React Native Integration
Native module pattern: JS calls PerkoxModule.showOfferwall, rewards arrive via NativeEventEmitter. Requires expo-dev-client or bare workflow.
Why Native Beats WebView
WebView offerwalls add 300ms+ latency and break on flaky connections. Native SDKs render instantly – 2-4x faster open-to-first-offer, which directly improves completion rates and revenue.
