Bad State: Future already completed (dio package )

[fearless23]

I am using example from https://github.com/GetStream/stream-feed-flutter/tree/master/example

Getting following error twice

Error: Bad state: Future already completed

Everything works as expected on iOS and Android, but on web the wheel is spinning
On Debugging, the debugger stops at browser_adapter.dart which is a dio package file

if (options.connectTimeout > 0) {
      // this is the code which throws the error
      Future.delayed(Duration(milliseconds: options.connectTimeout)).then(
        (value) {
          if (!haveSent) {
            completer.completeError(
              DioError(
                requestOptions: options,
                error: 'Connecting timed out [${options.connectTimeout}ms]',
                type: DioErrorType.connectTimeout,
              ),
              StackTrace.current,
            );
            xhr.abort();
          }
        },
      );
    }

Tried following

From

final client = StreamFeedClient(apiKey,  appId: 'xxxxxxx' );
// default timeout = 10 seconds

to

final client = StreamFeedClient(
      apiKey,
      appId: 'xxxxxxx',
      options: const StreamHttpClientOptions(
        connectTimeout: Duration(seconds: 30),
      ),
    );

But the issue persists
