  • 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Integrate the Linkrunner mobile attribution SDK into a Flutter/Dart app - add the package, initialize it, identify users, track events and revenue, and set up deep linking (iOS Universal Links, Android App Links, and custom URI schemes) with domain verification. Use when someone asks to add Linkrunner to a Flutter app, wire up attribution, or debug why Linkrunner deep links are not opening the app.

Linkrunner - Flutter integration

You are integrating Linkrunner (mobile attribution + deep linking) into a Flutter app. Work in this order and inspect the project before editing - do not paste snippets blindly.

0. Before you touch anything

  1. Confirm this is a Flutter app: there is a pubspec.yaml with a flutter: section and an android/ + ios/ (or lib/) tree.
  2. Find the app's entry point (usually lib/main.dart) and how it initializes (main() / initState).
  3. Ask the user for their project token (dashboard → Settings). If they use SDK signing, also get secretKey + keyId. Never hardcode these in a file that gets committed if the user keeps secrets elsewhere - ask where.
  4. Check current versions against requirements (below) before bumping anything.

1. Decide what the user actually needs

They want...Do this
"Add Linkrunner / set up attribution"references/install.md then references/events.md (at minimum init + signup)
"Set up deep links" / "links open the browser not my app"references/deep-linking.md + run scripts/verify-deeplinks.sh
"Track purchases / events"references/events.md
"Set up uninstall tracking"references/events.md (setPushToken section) - also needs FCM (Android) / APNs (iOS) wired up and configured in the Linkrunner dashboard

Most first-time integrations need install → init → signup → handle deeplink, in that order. Deep-link verification (AASA / assetlinks) is separate and is the part that usually breaks - treat it as its own step.

2. Requirements (verify, don't assume)

  • Flutter 3.19.0+, Dart 3.3.0+
  • Android minSdkVersion 21+, iOS deployment target 15.0+
  • Deep-link capture uses the app_links package; navigation examples use go_router. Check whether the app already has a router before adding one.

3. Golden rules

  • init() must run before any other Linkrunner call, after WidgetsFlutterBinding.ensureInitialized().
  • Call signup() the moment a user is identified (signup OR login) - this is what ties the install to a user. setUserData() is a later top-up, never a replacement.
  • For HTTP/HTTPS deep links, the app changes are worthless until the hosted assetlinks.json (Android) and apple-app-site-association (iOS) verify. Always finish by running scripts/verify-deeplinks.sh.
  • The Android SHA-256 fingerprint saved in Linkrunner must match the keystore that signed the build on the device. Debug and release differ.

4. Finish

After editing, run flutter pub get, build once, and run scripts/verify-deeplinks.sh <domain> <android_package> <ios_team_id.bundle_id> to confirm deep-link verification is actually live. Report which checks passed and which the user still has to do in the dashboard (host AASA/assetlinks under Project Settings → Domain Verification).
