Possibles values

Android

If the application was installed from a third party app (eg: GMail, Google Drive, Chrome…), it will be considered as a manual installation (InstallationAppReferrer.androidManually).

If the application was installed from a store (FDroid, Amazon App Shop…) which was not preinstalled on the device (a "non-system" app), it will also be considered as a manual installation (InstallationAppReferrer.androidManually).

If the Android application is in debug mode, it will be marked as InstallationAppReferrer.androidDebug.

iOS

If the iOS application is in debug mode (eg: from the simulator), it will be marked as InstallationAppReferrer.iosDebug.

Package name

You can also get the package name (Android) or app id (iOS), by calling instead InstallReferrer.app

Widgets

If you want to receive the result directly in a Widget, you have two choices: InstallReferrerDetectorListener and InstallReferrerDetectorBuilder :

InstallReferrerDetectorBuilder(
  builder: (BuildContext context, InstallationApp? app) {
    if (app == null) {
      return const CircularProgressIndicator.adaptive();
    } else {
      return Text(
        'Package name:\n${app.packageName ?? 'Unknown'}\n'
        'Referrer:\n${referrerToReadableString(app.referrer)}',
          textAlign: TextAlign.center,
      );
    }
  },
);

InstallReferrerDetectorListener(
  child: YourWidget(),
    onReferrerAvailable: (InstallationApp? app) {
      // TODO
    },
);
