The source was rewritten in Typescript completely.
Breaking changes
Add the buttons property
This prop is used to determine the mouse buttons that will activate the scroll on drag. The default value is [0], i.e. scroll on drag is activated by left mouse button only.
Remove the runtime type checking
It's recommended to use Typescript for type checking now.
Add the ScrollEvent to onScroll, onStartScroll, onEndScroll params.
It's the only argument of this functions now:
{
external: boolean;
}The external property marks if scrolling was produced outside the container, for example, programatically.
