Is there something similar to twitter bootstrap for React Native?

Question

React Native

Hello.
I look at different practices for structuring application content. Here one author suggests that in order not to litter the files with imports, create one xxx.js file, import all the necessary components there, connect it and, using named imports, use them. To me, this is of little use.
And in the process of viewing the above information, a question arose. For React Native, you will have to write repeated components many times, at least form components. What is usually done in this case? Do they create their own component with a bunch of elements and export everything they need named from there? Or maybe there are some special libraries like bootstrap? In different styles: some material design, flat, etc.
How are things going in this regard with React Native? Where are such visual components generally stored?
So far I have found one react.parts resource. But there components are not of a presentation level, they are functional.
