Don't render top and bottom content if it is not passed.

If I don't pass topContent or bottomContent, can it be not renderet at all? It looks like empty spaces and can't be removed via style.

Just set height = 0 for Top and Bottom. topViewStyle={{height: 0, flex: 0}} bottomViewStyle={{height: 0, flex: 0}}
