[iOS] Upgrader Dialog Does Not Work Well After User Returns From the AppStore

[achrafmam2]

Steps to reproduce:

1. Open App
2. Assuming the binary App is OLD, a dialog is shown
3. Click on Update
4. User is taken to the App store, return back to app WITHOUT updating
5. Click on Update

Expected Behavior: User is taken to the store Current Behavior: Alert Dialog is popped

Also, please include the upgrader version number from the pubspec.lock file, which should look something like this:

  upgrader:
    dependency: "direct main"
    description:
      name: upgrader
      sha256: d45483694620883107c2f5ca1dff7cdd4237b16810337a9c9c234203eb79eb5f
      url: "https://pub.dev"
    source: hosted
    version: "10.3.0"

Code

return MaterialApp.router(
      theme: MainTheme().light(),
      routerConfig: defaultAppRouter,
      localizationsDelegates: localizationsDelegates,
      supportedLocales: supportedLocales,
      scrollBehavior: const MaterialScrollBehavior().copyWith(
        dragDevices: {
          PointerDeviceKind.touch,
          PointerDeviceKind.mouse,
        },
      ),
      builder: (context, child) {
        const appcastURL = String.fromEnvironment("appcastUrl");
        final upgrader = Upgrader(
          storeController: UpgraderStoreController(
            oniOS: () => UpgraderAppcastStore(appcastURL: appcastURL),
            onAndroid: () => UpgraderAppcastStore(appcastURL: appcastURL),
          ),
          debugLogging: kDebugMode,
        );

        return UpgradeAlert(
          navigatorKey: defaultAppRouter.routerDelegate.navigatorKey,
          upgrader: upgrader,
          showReleaseNotes: false,
          child: child ?? Container(),
        );
      },
    );
  }

I tried to root cause the issue but didn't find the main culprit, but the UpgraderState::versionInfo gets null at some point. I've put several breakpoints but wasn't able to find where it gets null.
