Detect ScrollView has reached the end

Question

I have a Text with long text inside a ScrollView and I want to detect when the user has scrolled to the end of the text so I can enable a button.

Answer 1

For Horizontal ScrollView (e.g. Carousels) replace isCloseToBottom function with isCloseToRight

isCloseToRight = ({ layoutMeasurement, contentOffset, contentSize }) => {
    const paddingToRight = 20;
    return layoutMeasurement.width + contentOffset.x >= contentSize.width - paddingToRight;
};
