Respond to native bind animated event

Question

Need a little help with some JS. Is it possible to associate an animated event as needed below?

I need to do this:

onScroll={
    Animated.event([
        {
            nativeEvent: {
                contentOffset: {y: this.state.animTop}
            }
        }
    ])
}    

I also need to do this

onScroll={(e) => {
    let positionY =  e.nativeEvent.contentOffset.y;
    this._handleScroll(positionY);
    this.setState({y: positionY})

}}

I tried binding both types of this, but did not execute Animated.event

componentDidMount() {
    this._handleScroll = this._handleScroll.bind(this);
}
onScroll={
    this._handleScroll
}
_handleScroll(e) {
    Animated.event([
        {
            nativeEvent: {
                contentOffset: {y: this.state.animTop}
            }
        }
    ]);
    if(e > 30) {
        this.setState({statusBarHidden: true});
    } else {
        this.setState({statusBarHidden: false});
    }
}

Answer 1

Finally he earned:

Associate a function with an Animated.event listener:

onScroll={Animated.event(
                    [{ nativeEvent: { contentOffset: { y: this.state.animTop } } }],
                    { listener: this._handleScroll },
                )}

You can also use setValue().

So this will work as follows:

_handleScroll(event) {
    // Do stuff
    this.state.animTop.setValue(event.nativeEvent.contentOffset.y);
    // Do other stuff
}
