A lot of space under listview when try to insert element on the last position

two problems:
1. a lot of space under list view
2. very fast scrolling to the bottom (almost immediately)

Code:

replacePositions(e.from, e.to)}
renderRow={row => }
renderSeparator={() => }
renderFooter={this.renderAddPicture} />
