How to create Video call function in flutter app

I want to create video call function in my app.Can you suggest some ideas for video call function in flutter app?

Use this plugin

Jitsi_meet

And to join a meeting use

_joinMeeting() async {
try {
  FeatureFlag featureFlag = FeatureFlag();
  featureFlag.welcomePageEnabled = false;
  featureFlag.resolution = FeatureFlagVideoResolution.MD_RESOLUTION; // Limit video resolution to 360p
  
  var options = JitsiMeetingOptions()
    ..room = "myroom" // Required, spaces will be trimmed
    ..serverURL = "https://someHost.com"
    ..subject = "Meeting with Gunschu"
    ..userDisplayName = "My Name"
    ..userEmail = "myemail@email.com"
    ..userAvatarURL = "https://someimageurl.com/image.jpg" // or .png
    ..audioOnly = true
    ..audioMuted = true
    ..videoMuted = true
    ..featureFlag = featureFlag;

  await JitsiMeet.joinMeeting(options);
} catch (error) {
  debugPrint("error: $error");
}
}

The plug-in is open source and works great on ios and Android.
