### Get Device Push Token VoIP

Source: https://github.com/hiennguyen92/flutter_callkit_incoming/blob/master/README.md

iOS: returns deviceToken, Android: returns none

```dart
await FlutterCallkitIncoming.getDevicePushTokenVoIP();
```

--------------------------------

### Get device push token for VoIP (iOS)

Source: https://github.com/hiennguyen92/flutter_callkit_incoming/wiki/HOME

Retrieves the device push token for VoIP. For Android, this returns an empty string. The output is a device token. Make sure to use `SwiftFlutterCallkitIncomingPlugin.sharedInstance?.setDevicePushTokenVoIP(deviceToken)` inside AppDelegate.swift.

```dart
await FlutterCallkitIncoming.getDevicePushTokenVoIP();
```

```swift
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("")
}
```

--------------------------------

### Get Active Calls

Source: https://github.com/hiennguyen92/flutter_callkit_incoming/blob/master/README.md

Retrieves a list of active calls. On iOS, it returns call IDs; on Android, it returns the last call.

```dart
await FlutterCallkitIncoming.activeCalls();
```

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

    <!--
        Using for load image from internet
    -->
    <uses-permission android:name="android.permission.INTERNET"/>
</manifest>
```

```proguard
-keep class com.hiennv.flutter_callkit_incoming.** { *; }
```

--------------------------------

### Proguard Rules

Source: https://github.com/hiennguyen92/flutter_callkit_incoming/blob/master/README.md

### Call from Native (iOS)

Source: https://github.com/hiennguyen92/flutter_callkit_incoming/wiki/HOME

Demonstrates how to show an incoming callkit call from native Swift code. It's important to call `completion()` at the end of `pushRegistry(......, completion: @escaping () -> Void)` or use `DispatchQueue.main.asyncAfter(deadline: .now() + 1.5) { completion() }` to prevent app crashes.

```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)

//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
```

```swift
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)
```
