Taqlyn Flutter SDK (taqlyn_sdk)

Full guide: Flutter cookbook on the docs site.

Thin Flutter plugin that delegates to canonical native SdkCore (packages/sdk-android, packages/sdk-ios). Pub name: taqlyn_sdk.

App / sample Dart imports this package only — never Play Install Referrer or UIPasteboard types. Deferred Match stays in Kotlin/Swift.

Public API (sdk-contract)

await TaqlynSdk.configure(
  clientId: 'app_…',
  publicKeyId: 'pk_…',
  options: SdkOptions(
    linkProcessingMode: LinkProcessingMode.all, // all | webOnly | deferredOnly
    env: 'sandbox',
  ),
);

final share = await TaqlynSdk.createShareLink(destinationPath: '/offer');

final deferred = await TaqlynSdk.resolveDeferred(); // DeferredLink?
TaqlynSdk.observePlatformLinks().listen((link) async {
  // iOS: clipboard / UL. Android: referrer / App Links.
  await TaqlynSdk.consume(link.linkId);
});
// Or `package:taqlyn_sdk/ios.dart` / `package:taqlyn_sdk/android.dart`.
await TaqlynSdk.setReadyForNavigation(true);

DeferredLink mirrors packages/sdk-contract: url, path, params, linkId, matchType, isDeferred, campaign.

Architecture

Dart TaqlynSdk  →  MethodChannelNativeBridge (real plugin channel)
                      ├─ Android FlutterPlugin → com.taqlyn.sdk.SdkCore
                      └─ iOS FlutterPlugin     → TaqlynSDK.SdkCore

App / example code must use the MethodChannel bridge only. Unit tests may import package:taqlyn_sdk/testing.dart.

Optional soft helper: pub.dev taqlyn_nav_go_router (sibling packages/nav-go-router) for go_router redirect races — no Match logic.

Platform setup checklist

iOS

• Host AASA at https://<host>/.well-known/apple-app-site-association
• Enable Associated Domains (applinks:<host>) on the Runner target
• Call after WidgetsFlutterBinding.ensureInitialized() before configure
• Forward Universal Links: TaqlynSdkPlugin.handleOpenURL(url) from AppDelegate / scene
• Native SdkCore comes from published TaqlynSDK (CocoaPods / SPM). Host apps must not add a local packages/sdk-ios path.
• Deployment target iOS 16+ (matches sdk-ios)

Android

• Host assetlinks.json with Play App Signing SHA-256
• App Links intent filter + android:autoVerify="true" on the Activity
• Plugin Gradle depends on Maven Central com.taqlyn:taqlyn-sdk (published with the Android SDK)
• Emulators often cannot exercise Play Install Referrer — use a real device

Example

See example/ — flow:

configure → resolveDeferred → setReadyForNavigation → observeLinks → consume

Soft-uses taqlyn_nav_go_router for a pending-link holder.

cd example && flutter run
# Optional dart-defines:
# --dart-define=TAQLYN_CLIENT_ID=app_test_…
# --dart-define=TAQLYN_PUBLIC_KEY_ID=pk_test_…

Tests

# from packages/sdk-flutter
flutter test

• Fake NativeBridge proves ready-gate + DeferredLink mapping
• Mock MethodChannel proves channel argument mapping
• Source-guard: example/lib must not contain installreferrer / UIPasteboard

Native bridge host + example assemble (closes deferred / host risks)

# Android bridge → SdkCore (fake Install Referrer + sandbox ResolveClient)
cd android-host
./gradlew :bridge:testDebugUnitTest :bridge:assembleRelease

# Full Flutter host APK (plugin + example + sibling :taqlyn-sdk)
cd example && flutter build apk --debug
