* A Modal component covers the native view (e.g. UIViewController, Activity)

* that contains the React Native root.

*
|
|
* Use Modal in hybrid apps that embed React Native; Modal allows the portion of
|
|
* your app written in React Native to present content above the enclosing
|
|
* native view hierarchy.
|
|
*
|
|
* In apps written with React Native from the root view down, you should use
|
|
* Navigator instead of Modal. With a top-level Navigator, you have more control
|
|
* over how to present the modal scene over the rest of your app by using the
|
|
* configureScene property.
