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

Implementation

static Future<Map<String, dynamic>?> callExtension(String slug, String requestType, String endPoint, Map<String, dynamic>? body, {required Function(Map<String, dynamic> map)? onSuccess, required Function(CometChatException excep)? onError}) async {
  try {
    if (Platform.isIOS && endPoint.isNotEmpty && endPoint[0] == '/')
      endPoint = endPoint.substring(1);
    final result = await channel.invokeMethod('callExtension', {
      'slug': slug,
      'requestType': requestType,
      'endPoint': endPoint,
      'body': body,
    });
    var res;
    if (Platform.isIOS) {
      final _map = json.decode(result);
      res = {'data': _map};
    } else {
      final map = json.decode(result);
      res = Map<String, dynamic>.from(map);
    }
    if(onSuccess != null) onSuccess(res);
    return res;
  } on PlatformException catch (platformException) {
    if(onError != null) onError(CometChatException(platformException.code, platformException.details, platformException.message));
  } catch (e) {
    debugPrint("Error: $e");
    if(onError != null) onError(CometChatException(ErrorCode.errorUnhandledException, e.toString() , e.toString()));
  }
  return null;
}
