How to proper initialize?

[MigAlex]

At the readme file above initPlatformState() there is sth like: GoogleCast.instance.initialize(); but there is no such class like GoogleCast under the package. Is there any alternative approach?

Hi there,

Thank you for pointing out the issue in the documentation. You are correct, the documentation is outdated. To initialize the platform state, you need to use the following method:

Future<void> initPlatformState() async {
  const appId = GoogleCastDiscoveryCriteria.kDefaultApplicationId;
  GoogleCastOptions? options;
  if (Platform.isIOS) {
    options = IOSGoogleCastOptions(
      GoogleCastDiscoveryCriteriaInitialize.initWithApplicationID(appId),
    );
  } else if (Platform.isAndroid) {
    options = GoogleCastOptionsAndroid(
      appId: appId,
    );
  }
  GoogleCastContext.instance.setSharedInstanceWithOptions(options!);
}

The key part is to use GoogleCastContext.instance.setSharedInstanceWithOptions to set up the Google Cast context with the appropriate options based on the platform (iOS or Android).

I apologize for any confusion caused by the outdated documentation. We will update the documentation soon to reflect this change.

Hey, thanks for reply :)

If there is chance for the answer I'd like to ask about 'GoogleCastContext.instance.setSharedInstanceWithOptions(options!)' I fetched your example and hence signature of that part is Future<bool> I did in initPlatformState():

  final x = await GoogleCastContext.instance.setSharedInstanceWithOptions(options!);
    debugPrint('is it set up: $x');

but basically I didn't receive any return value. Overall, what I'm trying to do is getting information whether integration setup is working without active chromecast device around. So basically my question are:

• is there way to check whether integration is initialized and our app is looking for chromecast device (without chromecast around) OR we should fire up any callback yet? Because by this code portion:

     StreamBuilder<GoogleCastSession?>(
                stream: GoogleCastSessionManager.instance.currentSessionStream,
                builder: (context, snapshot) {
                  final isConnected = GoogleCastSessionManager.instance.connectionState ==
                      GoogleCastConnectState.ConnectionStateConnected;

  and answer GoogleCastConnectState.ConnectionStateDisconnected I understand it means we are just not connected to any device.

• is it intentional that await GoogleCastContext.instance.setSharedInstanceWithOptions(options!) returns nothing or sth is wrong?

Am working with Flutter 3.22 and Dart 3.4.0 and aiming for Android Devices.
