URL Launcher is used for opening URLs pasted in chat.

https://pub.dev/packages/url_launcher

Add the following to your pubspec.yaml file.

flutter_inappwebview: ^5.3.2

Edit the following in main.dart. There is no difference between creating and joining a meeting. A meeting gets created as soon as the first host joins the meeting.

You will need to fetch the roomName, displayName and jwt from your backend API.

For a full list of these properties that you can pass, please visit ClanMeeting properties page.

void _joinMeeting() async {
  const String domain = 'clanmeeting-domain';
  const String consumerId = 'your-consumer-id';
  const String roomName = 'meeting-room-name';
  const String displayName = 'participant-display-name';
  // if this participant is the host, not required if common participant
  const String jwt = 'the-jwt-from-backend-api';

Already included in example main.dart

// Request for camera and microphone permissions
await Permission.camera.request();
await Permission.microphone.request();

All JavaScript Events and Methods can be used within the app by editing the assets/clanmeeting.html. The example shows how to trigger a custom logic on Flutter side when the user leaves the meeting on app.

clanmeeting.html

// Events
const meetingLeftLsnr = function (data) {
  // Sends this data over to flutterEndCallHandler defined in clanmeeting.dart
  window.flutter_inappwebview.callHandler('flutterEndCallHandler', data);
};

meeting.once('meetingLeft', meetingLeftLsnr);

clanmeeting.dart

controller.addJavaScriptHandler(
    handlerName: 'flutterEndCallHandler',
    callback: (data) async {
        // data has arguments coming from the JavaScript side!
        debugPrint(
            'Data coming from Javascript side: $data');
        // ADD YOUR CUSTOM LOGIC HERE
        Navigator.pop(context);
    }
);
