access html method that is not defined in dart2js

Question

I need to access the replaceTrack method of the RtcRtpSender, however, it is not defined in the dart2js file:

@Native("RTCRtpSender")
class RtcRtpSender extends Interceptor {
  // To suppress missing implicit constructor warnings.
  factory RtcRtpSender._() {
    throw new UnsupportedError("Not supported");
  }

  MediaStreamTrack? get track native;
}

The replaceTrack method is defined here: https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpSender/replaceTrack

How can I call the RtcRtpSender.replaceTrack()?

I've tried the below and it threw _DartObject method not found:

JsObject.fromBrowserObject(myRtcRtpSender).callMethod('replaceTrack',
          [null]);

Answer 1

thanks to @sunbreak in gitter he reminded me of dart:js_util:

import 'package:js/js_util.dart' as js_util;

js_util.callMethod(myRtcRtpSender, 'replaceTrack',
          [null]);
