Not every app uses all the native capabilities, and including the code to support all those features would impact the binary size... But we still want to make it easy to add these features whenever you need them. With that in mind we exposed many of these features as independent static libraries. For most of the libs it will be as simple as dragging two files, sometimes a third step will be necessary, but no more than that. All the libraries we ship with React Native live on the Libraries folde

hitSlop {top: number, left: number, bottom: number, right: number} This defines how far a touch event can start away from the view. Typical interface guidelines recommend touch targets that are at least 30 - 40 points/density-independent pixels. If a Touchable view has a height of 20 the touchable height can be extended to 40 with hitSlop={{top: 10, bottom: 10, left: 0, right: 0}} NOTE The touch area never extends past the parent view bounds and the Z-index of sibling views always takes prec

iosalwaysBounceVertical bool When true, the scroll view bounces vertically when it reaches the end even if the content is smaller than the scroll view itself. The default value is false when horizontal={true} and true otherwise.

actions [{title: string, icon: optionalImageSource, show: enum('always', 'ifRoom', 'never'), showWithText: bool}] Sets possible actions on the toolbar as part of the action menu. These are displayed as icons or text on the right side of the widget. If they don't fit they are placed in an 'overflow' menu. This property takes an array of objects, where each object has the following keys: title: required, the title of this action icon: the icon for this action, e.g. require('./some_icon.png')

accessibilityLabel string Overrides the text that's read by the screen reader when the user interacts with the element. By default, the label is constructed by traversing all the children and accumulating all the Text nodes separated by space.
