Props

Prop name	Description	Type	Default value	Platform
`animationType`	Type of animation modal presented with	"none", "fade", "slide"	"none"
`backgroundColor`	Background color of the modal in HEX (#0099CC)	string	null
`controls`	Config of available controls (see below)	Object	{close: true}
`glideAlways`	Emulates ScrollView glide animation if built-in was not triggered	boolean	false	Android
`glideAlwaysDelay`	Defines delay in milliseconds for glideAlways	number	75	Android
`images`	Array of images to display, see below image item description	array	[]
`imageIndex`	Current index of image to display	number	0
`isVisible`	Is modal shown or not	boolean	false
`isTapZoomEnabled`	Zoom image when double tapped	boolean	true
`isPinchZoomEnabled`	Zoom image with pinch gesture	boolean	true
`isSwipeCloseEnabled`	Close modal with swipe up or down	boolean	true
`onClose`	Function called on modal closed	function	none
`renderFooter`	Function returns a footer element	function	none

Image item:

{
  source: any, // Image Component source object
  width: ?number, // Width of full screen image (optional but recommended)
  height: ?number, // Height of full screen image (optional but recommended)
  // any other props you need to render your footer
}

It's recommended to specify width and height to speed up rendering, overwise component needs to fetch images sizes and cache them in images objects passed as props.

controls prop:

type ControlType = React.Component<{onPress: () => void}> | null | boolean,

{
  close: ControlType // Component for close button in up right corner, as onPress prop accepts function to close modal
  next: ControlType, // Component for next image button, as onPress prop accepts function to scroll to next image
  prev: ControlType, // Component for previous image button, as onPress prop accepts function to scroll to previous image
}

To use default components just set {next: true, prev: true}, close is showing by default. To create custom controls check src/controls.
