Maybe not the best title :)
I need to make a screen that have header, scrollable content (which can contain for example thumbnail images with dynamic number) and footer which will contain buttons etc.

I know that this is easy to make with native base but does native base offer something that will keep footer at the bottom of the screen when content contain 3 or 4 images and of number of images is larger like 100 content should adapt to height of all this images (content) and now push footer down.

So footer stick to bottom when content is not large and when content is large to push footer down (off the screen) so you must scroll down to see footer again.
