I have a ScrollView (actually Animated.ScrollView) that I'd like to decide whether to allow vertically scroll or not on scroll start, based on some states of inner components. I know there is a scrollEnabled property which works but the scroll view contains some components that that a few frames to render and changing scrollEnabled property based on inner views' interactions cause a re-render, which drops a few frames and because of the nature of my app needing to change this property based on some animation/smooth scrolling of the inner views, those dropped frames cause a negative user experience.
I've also tried preventDefault of the scroll begin drag event but nothing changed (it allows scrolling regardless of I call it or not).
How can I decide whether or not to allow scrolling of scroll view dynamically on scroll start without a state/props update (which causes a re-render of an expensive view tree, dropping frames)? Something like pan responder's onMoveShouldSetPanResponder[Capture] events might be of great help but returning false from them just don't work (it captures and scrolls regardlessly even though they are called). (I'm on React Native 0.64)
