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.
