I get that error after updating to the latest react native version. Any suggestions?

in your component,

replace onScroll with

 onScroll={(e) => {

                const currentScrollPos = e.nativeEvent.contentOffset.y
                const sensitivity = 50

                if (Math.abs(currentScrollPos - this.state.lastScrollPos) > sensitivity) {

                            this.props.doSomething()
                            this.setState({lastScrollPos: e.nativeEvent.contentOffset.y })
                      }
  } }

I encountered this issue again. Anyone found a detailed and clear answer?
