Usage Example #
import 'package:mediasoup_client_flutter/mediasoup_client_flutter.dart';
import 'package:my_project/my_signaling.dart';

// Create a device.
final device = Device();

// Communicate with server app to retrieve router RTP capabilities.
final Map<String, dynamic> routerRtpCapabilities = await mySignaling.request('getRouterCapabilities');

// Load the device with the router RTP capabilities.
final rtpCapabilities = RtpCapabilities.fromMap(routerRtpCapabilities);
await device.load(routerRtpCapabilities: rtpCapabilities);

// Check wheter we can produce video to the router.
if (!device.canProduce(RTCRtpMediaType.RTCRtpMediaTypeVideo)) {
print('cannot produce video');
// Abort next steps.
}

// Create a transport in the server for sending our media through it.
final Map transportInfo = await mySignaling.request('createTransport', {
'forceTcp': false,
'producing': true,
'consuming': false,
'sctpCapabilities': device.sctpCapabilities.toMap(),
});

// Create a callback for producers.
void _producerCallback(Producer producer) {
/* Your code. */
}

final sendTransport = device.createSendTransportFromMap(
transportInfo,
producerCallback: _producerCallback,
);

// Set transport "connect" event handler.
sendTransport.on('connect', (Map data) {
// Here we must communicate our local parameters to our remote transport.
mySignaling.request('transport-connect', {
'transportId': _sendTransport.id,
'dtlsParameters': data['dtlsParameters'].toMap(),
})
// Done in the server, tell our transport.
.then(data['callback'])
// Something was wrong in server side.
.catchError(data['errback']);
});

// Set transport "produce" event handler.
_sendTransport.on('produce', (Map data) async {
// Here we must communicate our local parameters to our remote transport.
try {
Map response = await mySignaling.request(
'produce',
{
'transportId': sendTransport.id,
'kind': data['kind'],
'rtpParameters': data['rtpParameters'].toMap(),

);
// Done in the server, pass the response to our transport.
data['callback'](response['id']);
} catch (error) {
// Something was wrong in server side.
data['errback'](error);
}
});

// Produce our webcam video.
Map<String, dynamic> mediaConstraints = <String, dynamic>{
'audio': false,
'video': {
'mandatory': {
// Provide your own width, height and frame rate here.
'minWidth': '1280',
'minHeight': '720',

track: track,
source: 'webcam',

// Producer will return through _producerCallback.
