Initialise CometChat

1. appID - You CometChat App ID
2. appSettings - An object of the AppSettings class can be created using the AppSettingsBuilder class. The region field is mandatory and can be set using the setRegion() method.

• Region: The region where you app was created.
• Presence Subscription: Represents the subscription type for user presence (real-time online/offline status)
• autoEstablishSocketConnection(boolean value): This property takes a boolean value which when set to true informs the SDK to manage the web-socket connection internally. If set to false, it informs the SDK that the web-socket connection will be managed manually. The default value for this parameter is true. For more information on this, please check the Connection Behaviour section. The default value for this property is true.
• adminHost(adminHost: string): This method takes the admin URL as input and uses this admin URL instead of the default admin URL. This can be used in case of dedicated deployment of CometChat.
• clientHost(clientHost: string): This method takes the client URL as input and uses this client URL instead of the default client URL. This can be used in case of dedicated deployment of CometChat.

String region = "REGION";
String appId = "APP_ID";

AppSettings appSettings= (AppSettingsBuilder()
    ..subscriptionType = CometChatSubscriptionType.allUsers
    ..region= region
    ..adminHost = "" //optional
    ..clientHost = "" //optional
    ..autoEstablishSocketConnection =  true
).build();

CometChat.init(appId, appSettings,
  onSuccess: (String successMessage) {
    debugPrint("Initialization completed successfully  $successMessage");
  }, onError: (CometChatException excep) {
    debugPrint("Initialization failed with exception: ${excep.message}");
  }
);
