scanAllDlnaDevices function

Future<List<DiscoveredDevice>> scanAllDlnaDevices({
  1. Duration scanDuration = const Duration(seconds: 3),
  2. dynamic onDeviceFound(
    1. DiscoveredDevice
    )?,
})

Scan for all DLNA devices (including Renderers and Media Servers) onDeviceFound 回調函數，當找到新裝置時調用

Implementation

  // 使用 Future.wait 同時掃描兩種裝置
  final results = await Future.wait([

      onDeviceFound: onDeviceFound,
    ),
