Is Service Available
First check to be done before using the plugin features
Check if Snapchat Kit features can be usable. As the apps need instagram app on the running platform, its always good to check this before calling any of the other plugin methods.
public void IsAvailable()
bool isAvailable = SnapchatKitManager.IsAvailable();
string message = isAvailable ? "Snapchat Kit is available!" : "Snapchat Kit is not available. Snapchat app may not be installed.";
