# cast
Dart package to discover and connect with Chromecast devices
## Installation
Add this to your package's pubspec.yaml file:
```
dependencies:
cast: ^2.1.0
```
### iOS
Required iOS 13 minimum.
Since iOS 14 a few more steps are required https://developers.google.com/cast/docs/ios_sender/ios_permissions_changes
In `ios/Runner/Info.plist` add:
```xml
NSBonjourServices
_googlecast._tcp
_YOUR_APP_ID._googlecast._tcp
NSLocalNetworkUsageDescription
${PRODUCT_NAME} uses the local network to discover Cast-enabled devices on your WiFi
network.
```
## Usage
List devices:
```
Widget build(BuildContext context) {
return FutureBuilder>(
future: CastDiscoveryService().search(),
builder: (context, snapshot) {
if (snapshot.hasError) {
return Center(
child: Text(
'Error: ${snapshot.error.toString()}',
),
);
} else if (!snapshot.hasData) {
return Center(
child: CircularProgressIndicator(),
);
}
if (snapshot.data!.isEmpty) {
return Column(
children: [
Center(
child: Text(
'No Chromecast founded',
),
),
],
);
}
return Column(
children: snapshot.data!.map((device) {
return ListTile(
title: Text(device.name),
onTap: () {
_connectToYourApp(context, device);
},
);
}).toList(),
);
},
);
}
```
Connect to device:
```
Future _connect(BuildContext context, CastDevice object) async {
final session = await CastSessionManager().startSession(object);
session.stateStream.listen((state) {
if (state == CastSessionState.connected) {
_sendMessage(session);
}
});
session.messageStream.listen((message) {
print('receive message: $message');
});
session.sendMessage(CastSession.kNamespaceReceiver, {
'type': 'LAUNCH',
'appId': 'YouTube', // set the appId of your app here
});
}
```
`CastSessionManager` is used to keep track of all sessions.
Send message:
```
void _sendMessage(CastSession session) {
session.sendMessage('urn:x-cast:namespace-of-the-app', {
'type': 'sample',
});
}
```
Except for the launch message, you should wait until the session have a connected state before sending message.
