Cannot read property 'displayName' of undefined

See original GitHub issue

i am getting undefined error on itemComponent. the code from view.jsx

`const componentName = itemComponent.type.displayName || itemComponent.type.name;`

if you can explain MyMasonryItem class it would be really helpful right now
