callExtension static method

Future<Map<String, dynamic>?> callExtension(String slug, String requestType, String endPoint, Map<String, dynamic>? body, { required dynamic onSuccess(Map<String, dynamic> map)?, required dynamic onError(CometChatException excep)?, })

can call any extension

can be used in extensions like Pin message, Save message,Tiny Url, Bitly etc

method could throw PlatformException with error codes specifying the cause Calls a CometChat extension.

Migration Note: Migrated from platform channels to native Dart implementation. Uses ExtensionRepository for calling extensions. Behavior and signature remain identical for backward compatibility.

Android Reference: CometChat.callExtension(String slug, String type, String endpoint, JSONObject body, CallbackListener<JSONObject>)

Implementation

    String requestType, String endPoint, Map<String, dynamic>? body,
    {required Function(Map<String, dynamic> map)? onSuccess,
    required Function(CometChatException excep)? onError}) async {

    // Validate parameters
    if (slug.isEmpty) {
      onError?.call(CometChatException(
          ErrorCode.errorEmptyExtensionSlug,
          ErrorMessage.errorMessageEmptyExtensionSlug,
          ErrorMessage.errorMessageEmptyExtensionSlug));
      return null;
    }

      return null;

    // Normalize endpoint (remove leading slash for consistency)
    if (endPoint.isNotEmpty && endPoint[0] == '/') {
