I want to change the position of the scroll when I change the visibity. As users scroll in the scroll view, this object should add and remove subviews as necessary. They accept ScrollView, ListView, SectionList and FlatList default props respectively and implement a custom high order componente called KeyboardAwareHOC to handle keyboard appearance. Scroll View is used for displaying content more than the size of the screen. This is where View Preferences come handy. Quiero desplazarme programáticamente a una vista contenida en algún lugar de su jerarquía. For example, we could create a scroll list of ten text views like. Returns a task that scrolls the scroll view to a position asynchronously. It also enables and disables the scrolling animation when changing the view. A note: I read where people were changing the deceleration of the scroll view to make it feel even snappier. You might do this by constraining the subview to some superview of the scroll view but that can be tricky.
