Reconnecting with a server error does not work

[wildCherryTO]

At the moment when the server returns an error, reconnection does not work. The problem is in the code section (see below).
The problem is with "return" after calling onError.

File: client.dart

  if (data.statusCode < 200 || data.statusCode >= 300) {
    String responseBody = await data.stream.bytesToString();
    if (onError != null) {
      Map<String, dynamic>? errorDetails;
      try {
        errorDetails = jsonDecode(responseBody);
      } catch (e) {
        errorDetails = {'rawBody': responseBody};
      }

      onError(
        EventFluxException(
          statusCode: data.statusCode,
          reasonPhrase: data.reasonPhrase,
          message: errorDetails.toString().isEmpty
              ? data.reasonPhrase
              : errorDetails.toString(),
        ),
      );
    }
    return;
  }

  if (autoReconnect && data.statusCode != 200) {
    _attemptReconnectIfNeeded(
      _isExplicitDisconnect,
      autoReconnect,
      type,
      url,
      header,
      onSuccessCallback,
      onError: onError,
      onConnectionClose: onConnectionClose,
      httpClient: httpClient,
      body: body,
      files: files,
      multipartRequest: multipartRequest,
    );
    return;
  }

@wildCherryTO did you find a way around this?

Hi! As I wrote above, the problem lies in your code section, where you throw an onError and make a return for any response code less than 200 or more than 300. Thus, you break the logic of reconnection. I bypassed this from my side in my wrapper, as my business demanded. I would be grateful if you would review your code again and correct it. Maybe I didn't do it quite right.
