updateTimezone static method

Future<String?> updateTimezone(String timezone, { dynamic onSuccess(String response)?, dynamic onError(CometChatException e)?, })

Updates the timezone preference for the logged-in user.

This method makes an asynchronous call to the CometChat server to update the timezone preference for the logged-in user. Upon successful update, onSuccess is invoked with a success response. If an error occurs, onError is called with a CometChatException.

Returns a Future<String>, which completes with a success response if the operation is successful, or null if an error occurs.

Implementation

static Future<String?> updateTimezone(String timezone,
    {Function(String response)? onSuccess,
    Function(CometChatException e)? onError}) async {
  if (timezone.isEmpty) {
    _handleError(
        CometChatException(
            ErrorCode.errorInvalidTimezone,
            ErrorMessage.errorInvalidEmptyTimezone,
            ErrorMessage.errorInvalidEmptyTimezone),
        onError);
    return null;
  }

  try {
    final sdk = SdkRegistry.getInstance();
    await sdk.notificationsApi.updateTimezone(timezone);

    const result = 'Timezone updated successfully';
    if (onSuccess != null) onSuccess(result);
    return result;
  } catch (e) {
    _handleError(e, onError);
  }
  return null;
