We getting fewer points on basic staff that we can easily improve.

For example to get the static analysis points we just need to run dart format ..

In the Provide documentation section we missing the example section which exists and we just need to show it correctly for pub.dev.
And there are more.

If needed I will be happy to try getting more points.

This is a very good library to play videos from flutter application to Chromecast. We are unable to find the way to play DRM content which has license for the video content. Is it possible to play DRM content with this library. If possible let us know the code clues.

Here is the sample code for playing DRM content with shaka player in web version. Adding this link just to refer the license passing for DRM content.

Hi,
I'm using the chromecast to display a web page and I need to be able to send custom message.
For this I need to create my own CastChannel with my own namespace and the destinationId should be the transporterId like for the MediaChannel.

I can do everything except accessing the _socket property required to create the channel.

Moving to null safety should be top priority.

Without support for null safety this package will not get new users as everybody is moving to it.

It is stopping me from using this package and I am sure it is not just me.

hi please is there anyway to send request headers like user agent or cookie ?

Is it possible to mirror/cast app screen on the chromecast device using this package?

The example is using a .mp4 video that can be found on a public URL.

Is there a way to open web pages or youtube videos by sending URLs?

Can I screenshare an app from the mobile to the Chromecast with this ?

You only mention casting videos in the readme

Thanks !

I am using audio_cast but the error seems to be from dart_chromecast , how can i fix this?

There is a breaking change in the protobuf plugin that dart_chromecast depends on.

Latest version supported is protobuf: 0.13.16+1

google/protobuf.dart#284

Hi, thanks for publishing this great plugin, I'm using in my streaming app called FarmTUBE (free). The only issue is the friendly name comes back "Unknown" on iPhones/iPads . It still streams fine, it's just an issue selecting the correct device in a house with multiple Chromecasts. I've tested a number of apple phones at different houses with the same result, it works perfectly on Android devices.

I'm using a gen2 Chromecast (i have many of them)

I would be willing to pay £50 for a fix to this bug as casting is the primary purpose of my app.

Thanks
Stuart

Hi, so I am trying to integrate Chromecast into my media player and noticed that my app cannot disconnect from the device no matter what state it is in. Calling CastSender.disconnect() outputs this to the debug console:

(* current latest provided with Flutter SDK. I'm not making an Android/iOS app in this case, just REPLing with dart_chromecast. I'm curious if I'd hit a similar issue on Android, though.)

Is it possible with the package 'camera' to cast my device camera stream in real-time?

The funcion find_chromecast.find_chromecasts() is not able to return any device in network, and trow an error :
"Dart Socket ERROR: ../../third_party/dart/runtime/bin/socket_android.cc:147: reusePort not supported for Android."

The error can be fixed adding rawDatagramSocketFactory to MDnsClient() but it stills not returning any device.

My code:

 @override
  void initState() {
    findCastingDevices();

    super.initState();
  }

Future<void> findCastingDevices() async {
    // search!
    print('Looking for ChromeCast devices...');
    devices = (await find_chromecast.find_chromecasts()).cast<find_chromecast.CastDevice>();
    if (devices.length == 0) {
      print('No devices found!');
      Future.delayed(Duration(seconds: 45), () {
        findCastingDevices();
      });
      return;
    }

    print("Found ${devices.length} devices:");
    for (int i = 0; i < devices.length; i++) {
      int index = i + 1;
      find_chromecast.CastDevice device = devices[i];
      print("$index: ${device.name}");
    }
    setState(() {});
  }

On our pub.dev score page it is written that the package's version is not up to date.

let's update and increase our pub.dev score.

Hi, this is more a question than an issue, does this package support flutter web ? I know that mdns isn't working on web so I was wondering.
Thanks

Since Dart 1.12 dart_chromecast does not pass static analysis on pub.dev.
This also applies to packages depending on this library and thus is crucial to me.

Trying to use this library but having an issue when trying to get a CastDevice

CastDevice device = CastDevice(name:info.name,host: info.address,port:info.port,type: '_googlecast._tcp');

This gives me the error:

Hi,
it doesnt seem to be working on iOS. Searching for devices returns no results

I cannot run flutter, since the old flutter_svg package (v 0.17) produces errors on the newest version of flutter: 1.20.1.
But I can't upgrade the package to 0.18, since it requires xml ^4.1.0, and dart_chromecast 0.1.2 depends on xml ^3.0.0 and it is not possible to use the xml ^4.1.0 because of this.

Is it possible for me to manually override what this package depends on?

Original (Not working, /lib/casting/cast_sender.dart)

  void setVolume(double volume) {
    Map<String, dynamic> map = {'volume': min(volume, 1)};
    _castMediaAction('VOLUME', map);
  }

void _castMediaAction(type, [params]) {
    if (null == params) params = {};
    if (null != _mediaChannel && null != _castSession?.castMediaStatus) {
      _mediaChannel.sendMessage(params
        ..addAll({
          'mediaSessionId': _castSession.castMediaStatus.sessionId,

Hi,
Thank you so much for this awesome plugin. I was just wondering if it is possible to change playback speed of the casted audio/video? I couldn't find it anywhere in the code.
