  await FlutterCallkitIncoming.endCall(params);

Ended all calls

  await FlutterCallkitIncoming.endAllCalls();

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

  await FlutterCallkitIncoming.activeCalls();

Output

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

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((event) {
    switch (event!.name) {
      case CallEvent.ACTION_CALL_INCOMING:
        // TODO: received an incoming call
        break;
      case CallEvent.ACTION_CALL_START:
        // TODO: started an outgoing call
        // TODO: show screen calling in Flutter

  //... set more data
  SwiftFlutterCallkitIncomingPlugin.sharedInstance?.showCallkitIncoming(flutter_callkit_incoming.Data(args: info), fromPushKit: true)

  //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)

  //Objective-C
  #if __has_include(<flutter_callkit_incoming/flutter_callkit_incoming-Swift.h>)
  #import <flutter_callkit_incoming/flutter_callkit_incoming-Swift.h>
  #else

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

  //send custom event from native
