Example Project 😍

You can checkout the example project 🥰

Simply run

• npm i && npx pod-install
• react-native run-ios/android

should work of the example project.

How it works

The tooltip wraps an element in place in your React Native rendering. When it renders, it measures the location of the element, using React Native's measure. When the tooltip is displayed, it renders a copy of the wrapped element positioned absolutely on the screen at the coordinates returned after measuring (see TooltipChildrenContext below if you need to tell the difference between the copy and the original element). This allows you to touch the element in the tooltip modal rendered above your current screen.

Props

Prop name	Type	Default value	Description
accessible	bool	true	Set this to false if you do not want the root touchable element to be accessible. See docs on accessible here
allowChildInteraction	bool	true	By default, the user can touch and interact with the child element. When this prop is false, the user cannot interact with the child element while the tooltip is visible.
arrowSize	Size	{ width: 16, height: 8 }	The dimensions of the arrow on the bubble pointing to the highlighted element
backgroundColor	string	'rgba(0,0,0,0.5)'	Color of the fullscreen background beneath the tooltip. Overrides the backgroundStyle prop
childContentSpacing	number	4	The distance between the tooltip-rendered child and the arrow pointing to it
closeOnChildInteraction	bool	true	When child interaction is allowed, this prop determines if onClose should be called when the user interacts with the child element. Default is true (usually means the tooltip will dismiss once the user touches the element highlighted)
closeOnContentInteraction	bool	true	this prop determines if onClose should be called when the user interacts with the content element. Default is true (usually means the tooltip will dismiss once the user touches the content element)
content	function/Element	<View />	This is the view displayed in the tooltip popover bubble
displayInsets	object	{ top: 24, bottom: 24, left: 24, right: 24 }	The number of pixels to inset the tooltip on the screen (think of it like padding). The tooltip bubble should never render outside of these insets, so you may need to adjust your content accordingly
disableShadow	bool	false	When true, tooltips will not appear elevated. Disabling shadows will remove the warning: RCTView has a shadow set but cannot calculate shadow efficiently on IOS devices.
isVisible	bool	false	When true, tooltip is displayed
onClose	function	null	Callback fired when the user taps the tooltip background overlay
placement	string	"top" | "center"	Where to position the tooltip - options: top, bottom, left, right, center. Default is top for tooltips rendered with children Default is center for tooltips rendered without children. NOTE: center is only available with a childless placement, and the content will be centered within the bounds defined by the displayInsets.
showChildInTooltip	bool	true	Set this to false if you do NOT want to display the child alongside the tooltip when the tooltip is visible
supportedOrientations	array	["portrait", "landscape"]	This prop allows you to control the supported orientations the tooltip modal can be displayed. It correlates directly with the prop for React Native's Modal component (has no effect if useReactNativeModal is false)
topAdjustment	number	0	Value which provides additional vertical offest for the child element displayed in a tooltip. Commonly set to: Platform.OS === 'android' ? -StatusBar.currentHeight : 0 due to an issue with React Native's measure function on Android
horizontalAdjustment	number	0	Value which provides additional horizontal offest for the child element displayed in a tooltip. This is useful for adjusting the horizontal positioning of a highlighted child element if needed
useInteractionManager	bool	false	Set this to true if you want the tooltip to wait to become visible until the callback for InteractionManager.runAfterInteractions is executed. Can be useful if you need to wait for navigation transitions to complete, etc. See docs on InteractionManager here
useReactNativeModal	bool	true	By default, this library uses a <Modal> component from React Native. If you need to disable this, and simply render an absolutely positioned full-screen view, set useReactNativeModal={false}. This is especially useful if you desire to render a Tooltip while you have a different Modal rendered.

Style Props

The tooltip styles should work out-of-the-box for most use cases, however should you need you can customize the styles of the tooltip using these props.

Prop name	Effect
arrowStyle	Styles the triangle that points to the called out element
backgroundStyle	Styles the overlay view that sits behind the tooltip, but over the current view
childrenWrapperStyle	Styles the view that wraps cloned children
contentStyle	Styles the content wrapper that surrounds the content element
tooltipStyle	Styles the tooltip that wraps the arrow and content elements

Class definitions for props

• Size is an object with properties: { width: number, height: number }

TooltipChildrenContext

React Context that can be used to distinguish "real" children rendered inside parent's layout from their copies rendered inside tooltip's modal. The duplicate child rendered in the tooltip modal is wrapped in a Context.Provider which provides object with prop tooltipDuplicate set to true, so informed decisions may be made, if necessary, based on where the child rendered.

import Tooltip, { TooltipChildrenContext } from 'react-native-walkthrough-tooltip';
...
<Tooltip>
  <ComponentA />
  <ComponentB>
    <TooltipChildrenContext.Consumer>
      {({ tooltipDuplicate }) => (
        // Will only assign a ref to the original component
        <FlatList {...(!tooltipDuplicate && { ref: this.listRef })} />
      )}
    </TooltipChildrenContext.Consumer>
  </ComponentB>
</Tooltip>

Credits

This library is a fork of react-native-walkthrough-tooltip

• Full typescript re-written
• Much better types and props
• Better customizability

Future Plans

• [x] LICENSE
• [ ] Code separation rely on separation of concern(SoC)
• [ ] Code cleanup and refactoring
• [ ] Better README and documentation
• [ ] Write an article about the lib on Medium
