discoverBridgeServers function

Future<List<BridgeServerInfo>> discoverBridgeServers({ String host = 'localhost', List<int> ports = const [19836, 19837, 19838, 19839, 19840], Duration timeout = const Duration(seconds: 2), })

Discover running bridge servers on common ports.

Attempts to connect to a range of ports and returns any that respond with a valid handshake.

Implementation

  Duration timeout = const Duration(seconds: 2),
}) async {

      _probePort(host, port, timeout)
          .then((info) {

          })
          .catchError((Object _) {
            // Port not available — skip.
          }),
