                </TouchableOpacity>
              </View>
            </View>
          )}
          scrollableViewStyle={{ backgroundColor: 'red' }}
        >

But I've got error.

What's the matter?

Thing to changing is one it is backgroundSource require('image!backgroundImage') -> null.
I don't need backgroundSource and it's just white.
but before to change is error too.

And I tried to remove backgroundSource, but it's a same error (Cannot read 'number').

Samething as soon as I import the lib

Same here!

Because the PropTypes in this project is imported with React.PropTypes which is not compatible with newer version of react native.

The correct way should be, import PropTypes from 'prop-types';

Please fix this!

Fucking dickhead. if you are not going to fix the issues might as well not create the library. asshole @lelandrichardson

This repository doesn't seem to be maintained.
I created the same library that solved this problem.
