Event callbacks

The DotLottieAnimation instance emits the following events that can be listened to via a class implementing the Observer protocol:

class YourDotLottieObserver: Observer {
    func onComplete() {
        // do something
    }


    func onFrame(frameNo: Float) {
        // do something
    }


    func onLoad() {
        // do something
    }


    func onLoadError() {
        // do something
    }


    func onLoop(loopCount: UInt32) {
        // do something
    }


    func onPause() {
        // do something
    }


    func onPlay() {
        // do something
    }


    func onRender(frameNo: Float) {
        // do something
    }


    func onStop() {
        // do something
    }
}


// In your view code


var animation = DotLottieAnimation(...)
var animationView = DotLottieView(dotLottie: animation)
var myObserver = YourDotLottieObserver()


animationView.subscribe(observer: myObserver)
