• Show miss call notification

    this._currentUuid = _uuid.v4();
    var params = <String, dynamic>{
      'id': this._currentUuid,
      'nameCaller': 'Hien Nguyen',
      'handle': '0123456789',

    };
    await BilltechIncomingCall.showMissCallNotification(params);
  

• Started an outgoing call

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

• Ended an incoming/outgoing call

    var params = <String, dynamic>{'id': this._currentUuid};
    await BilltechIncomingCall.endCall(params);
  

• Ended all calls

    await BilltechIncomingCall.endAllCalls();
  

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

    await BilltechIncomingCall.activeCalls();
  

  Output

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

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

    await BilltechIncomingCall.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

    BilltechIncomingCall.onEvent.listen((event) {
      switch (event!.name) {
        case CallEvent.ACTION_CALL_INCOMING:
          // TODO: received an incoming call
          break;
        case CallEvent.ACTION_CALL_START:

    });
  

• Call from Native (iOS PushKit)

    //Swift
    var info = [String: Any?]()
    info["id"] = "44d915e1-5ff4-4bed-bf13-c423048ec97a"
    info["nameCaller"] = "Hien Nguyen"
    info["handle"] = "0123456789"
    info["type"] = 1
    //... 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
    #import "flutter_callkit_incoming-Swift.h"
    #endif
  
    Data * data = [[Data alloc]initWithId:@"44d915e1-5ff4-4bed-bf13-c423048ec97a" nameCaller:@"Hien Nguyen" handle:@"0123456789" type:1];
    [data setNameCaller:@"Johnny"];
    [data setExtra:@{ @"userId" : @"HelloXXXX", @"key2" : @"value2"}];
    //... set more data
    [SwiftFlutterCallkitIncomingPlugin.sharedInstance showCallkitIncoming:data fromPushKit:YES];
  

  
  

    //send custom event from native
