superwallAndroidSetupHintFor function
Superwall-specific Android hint. The runtime auto-injects the
SuperwallPaywallActivity per Superwall's install docs, so the only thing
the consumer must do manually is raise minSdkVersion to 26 — Flutter's
historical default of 21 fails the build.
Empty when no Android key was provided so iOS-only projects don't see noisy Android guidance.
Implementation
String superwallAndroidSetupHintFor({required bool androidKeyProvided}) {
if (!androidKeyProvided) return '';
return 'Android Setup'
'\n- Set `minSdkVersion 26` (or higher) in `android/app/build.gradle` — Superwall requires it'
'\n\n';
}
