3. Usage

• Import

  import 'package:flutter_callkit_incoming/flutter_callkit_incoming.dart';
  

• Received an incoming call

    this._currentUuid = _uuid.v4();
    CallKitParams callKitParams = CallKitParams(
      id: _currentUuid,
      nameCaller: 'Hien Nguyen',
      appName: 'Callkit',
      avatar: 'https://i.pravatar.cc/100',

      missedCallNotification: NotificationParams(
          showNotification: true,
          isShowCallback: true,
          subtitle: 'Missed call',
          callbackText: 'Call back',
      ),
      duration: 30000,
      extra: <String, dynamic>{'userId': '1a2b3c4d'},
      headers: <String, dynamic>{'apiKey': 'Abc@123!', 'platform': 'flutter'},
      android: const AndroidParams(
          isCustomNotification: true,
          isShowLogo: false,
          ringtonePath: 'system_ringtone_default',
          backgroundColor: '#0955fa',

• request permission for post Notification Android 13+ For Android 13 and above, please requestNotificationPermission before showCallkitIncoming

    await FlutterCallkitIncoming.requestNotificationPermission({
      "rationaleMessagePermission": "Notification permission is required, to show notification.",
      "postNotificationMessageRequired": "Notification permission is required, Please allow notification permission from setting."
    });
  

• 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["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)
        
    //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)
  

  
  

    //Objective-C

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

  
  

    //send custom event from native
