Show miss call notification

  this._currentUuid = _uuid.v4();
  CallKitParams params = CallKitParams(
    id: _currentUuid,
    nameCaller: 'Hien Nguyen',
    handle: '0123456789',
    type: 1,
    textMissedCall: 'Missed call',
    textCallback: 'Call back',
    extra: <String, dynamic>{'userId': '1a2b3c4d'},
  );
  await FlutterCallkitIncoming.showMissCallNotification(params);

Started an outgoing call

  this._currentUuid = _uuid.v4();
  CallKitParams params = CallKitParams(
    id: this._currentUuid,
    nameCaller: 'Hien Nguyen',
    handle: '0123456789',
    type: 1,
    extra: <String, dynamic>{'userId': '1a2b3c4d'},
    ios: IOSParams(handleType: 'generic')
  );
  await FlutterCallkitIncoming.startCall(params);

Ended an incoming/outgoing call

  await FlutterCallkitIncoming.endCall(this._currentUuid);

Ended all calls

  await FlutterCallkitIncoming.endAllCalls();

Get active calls. iOS: return active calls from Callkit(only id), Android: only return last call

  await FlutterCallkitIncoming.activeCalls();

Output

[{"id": "8BAA2B26-47AD-42C1-9197-1D75F662DF78", ...}]

Set status call connected (only for iOS - used to determine Incoming Call or Outgoing Call status in phone book)
```
  await FlutterCallkitIncoming.setCallConnected(this._currentUuid);
```
After the call is ACCEPT or startCall please call this func. normally it should be called when webrtc/p2p.... is established.

Get device push token VoIP. iOS: return deviceToken, Android: Empty

  await FlutterCallkitIncoming.getDevicePushTokenVoIP();

Output

<device token>

//Example
d6a77ca80c5f09f87f353cdd328ec8d7d34e92eb108d046c91906f27f54949cd

Make sure using SwiftFlutterCallkitIncomingPlugin.sharedInstance?.setDevicePushTokenVoIP(deviceToken) inside AppDelegate.swift (Example)

func pushRegistry(_ registry: PKPushRegistry, didUpdate credentials: PKPushCredentials, for type: PKPushType) {
    print(credentials.token)
    let deviceToken = credentials.token.map { String(format: "%02x", $0) }.joined()
    //Save deviceToken to your server
    SwiftFlutterCallkitIncomingPlugin.sharedInstance?.setDevicePushTokenVoIP(deviceToken)
}

func pushRegistry(_ registry: PKPushRegistry, didInvalidatePushTokenFor type: PKPushType) {
    print("didInvalidatePushTokenFor")
    SwiftFlutterCallkitIncomingPlugin.sharedInstance?.setDevicePushTokenVoIP("")
}

Listen events

  FlutterCallkitIncoming.onEvent.listen((CallEvent event) {
    switch (event!.event) {
      case Event.actionCallIncoming:
        // TODO: received an incoming call
        break;
      case Event.actionCallStart:
        // TODO: started an outgoing call
        // TODO: show screen calling in Flutter
        break;
      case Event.actionCallAccept:
        // TODO: accepted an incoming call
        // TODO: show screen calling in Flutter
        break;
      case Event.actionCallDecline:
        // TODO: declined an incoming call
        break;
      case Event.actionCallEnded:
        // TODO: ended an incoming/outgoing call
        break;
      case Event.actionCallTimeout:
        // TODO: missed an incoming call
        break;
      case Event.actionCallCallback:
        // TODO: only Android - click action `Call back` from missed call notification
        break;
      case Event.actionCallToggleHold:
        // TODO: only iOS
        break;
      case Event.actionCallToggleMute:
        // TODO: only iOS
        break;
      case Event.actionCallToggleDmtf:
        // TODO: only iOS
        break;
      case Event.actionCallToggleGroup:
        // TODO: only iOS
        break;
      case Event.actionCallToggleAudioSession:
        // TODO: only iOS
        break;
      case Event.actionDidUpdateDevicePushTokenVoip:
        // TODO: only iOS
        break;
      case Event.actionCallCustom:
        // TODO: for custom action
        break;
    }
  });

Call from Native (iOS/Android)

  //Swift iOS
  var info = [String: Any?]()

  info["type"] = 1
  //... set more data
  SwiftFlutterCallkitIncomingPlugin.sharedInstance?.showCallkitIncoming(flutter_callkit_incoming.Data(args: info), fromPushKit: true)
  
  //please make sure call `completion()` at the end of the pushRegistry(......, completion: @escaping () -> Void)
  // or `DispatchQueue.main.asyncAfter(deadline: .now() + 1.5) { completion() }`
  // if you don't call completion() in pushRegistry(......, completion: @escaping () -> Void), there may be app crash by system when receiving voIP

    //Kotlin/Java Android
    FlutterCallkitIncomingPlugin.getInstance().showIncomingNotification(...)

  //OR
  let data = flutter_callkit_incoming.Data(id: "44d915e1-5ff4-4bed-bf13-c423048ec97a", nameCaller: "Hien Nguyen", handle: "0123456789", type: 0)
  data.nameCaller = "Johnny"
  data.extra = ["user": "abc@123", "platform": "ios"]
  //... set more data
  SwiftFlutterCallkitIncomingPlugin.sharedInstance?.showCallkitIncoming(data, fromPushKit: true)

  [data setNameCaller:@"Johnny"];
  [data setExtra:@{ @"userId" : @"HelloXXXX", @"key2" : @"value2"}];
  //... set more data
  [SwiftFlutterCallkitIncomingPlugin.sharedInstance showCallkitIncoming:data fromPushKit:YES];

  //send custom event from native
