One app store link for your Flutter app

Open the link from Dart

Flutter apps often have a “Share the app”, “Rate us” or “Get the full version” button. With one Jumper link behind it, the same Dart code serves both platforms: no Platform.isIOS check and no two store addresses to keep in sync. If the app moves to a new listing, change the link in the dashboard; old app versions in the wild follow.

// pubspec.yaml: url_launcher
import 'package:url_launcher/url_launcher.dart';

/// Your Jumper link: the App Store on iPhone, Google Play on Android, your site elsewhere.
const appLink = 'https://oxi.cc/urapp';

Future<void> openStore() async {
  final ok = await launchUrl(Uri.parse(appLink), mode: LaunchMode.externalApplication);
  if (!ok) debugPrint('Could not open $appLink');
}

// A "Share the app" button: one link that works for iPhone and Android friends.
// share_plus: await SharePlus.instance.share(ShareParams(text: 'Get the app: $appLink'));

Read the Google Play referrer in Dart

This tells your app which Jumper link and campaign brought the install. It is optional: the stores count installs per campaign either way. The play_install_referrer package (the maintained fork of android_play_install_referrer) wraps Google’s Install Referrer library. Apple gives apps no referrer, so on iOS the function returns null and you read campaigns in App Store Connect.

// pubspec.yaml: play_install_referrer
import 'package:play_install_referrer/play_install_referrer.dart';

/// The Jumper link id and campaign, or null when the install did not come from a Jumper link.
Future<Map<String, String>?> readJumperReferrer() async {
  try {
    final details = await PlayInstallReferrer.installReferrer;
    final raw = details.installReferrer; // utm_source=yt&utm_medium=description&…&jumper=lnk_…
    if (raw == null) return null;
    final query = Uri.splitQueryString(raw);
    final linkId = query['jumper'];
    return linkId == null ? null : {'link': linkId, 'campaign': query['utm_campaign'] ?? ''};
  } catch (_) {
    return null; // iOS, or no Google Play services
  }
}

Privacy policy, terms and support pages

Both stores ask for a privacy policy link before they accept your app, and Apple also asks for a support link. With Jumper.to you write or paste each page as plain text (or upload a .md file) and get an address like oxi.cc/<your link>/privacy-policy. Pages are text only: headings, lists, tables and links, no images or scripts. Each page uses one credit, like a link. Paste the privacy policy address in App Store Connect and Google Play Console before you submit.
