React Native Gesture Detector

Create and detect custom gestures on React Native.


Example app and usage

Feel free to test Snack Expo demo or run the included demo app locally:

$ git clone https://github.com/mxmzb/react-native-gesture-detector.git
$ cd react-native-gesture-detector/example
$ yarn
$ yarn start

Check the code for the screens to see how they are done!


This package originated from a real life need to detect custom gestures. The idea for implementation originated from this stellar answer on StackOverflow. The result is not 100% foolproof, but rock solid, performant and extremely simple to use.

The package comes with another, insanely cool component GestureRecorder, which allows you to create gestures on the fly. Yep, just plug it in, paint the gesture and you will receive the coordinate data for your supercomplex, custom gesture. You can use it to just use the data points as a predefined gesture in your app, or you can even let your app users create their own custom gestures, if that fits your game plan!

Because the library significantly uses React hooks, you must use at least react@16.8.0.


$ yarn add react-native-gesture-detector

import GestureDetector, {
} from "react-native-gesture-detector";

const gestures = {
  // this will result in the gesture shown in the first demo give above
  Coil: [
    { x: 10, y: -30 }, // This is a coordinate object
    { x: 25, y: -15 },
    { x: 40, y: -10 },
    { x: 55, y: -15 },

        {coordinate && <Cursor {...coordinate} />}

const RecordGestureExample = () => {

  const [finishedGesture, setFinishedGesture] = useState([]);

Documentation and API


GestureDetector is a render props component. The child function has the form children({ coordinate: { x: number, y: number } })

slopRadius50numberThe radius in px from a coordinate. The resulting circle is the area in which the user can move the finger
gestures{}{ [key: string]: [{ x: number, y: number }] }An object with one or more gestures. A gesture is an array of { x, y } objects, which symbolize the exact coordinates you want the user to pass
onProgress({ progress, gesture }) => {}functionA callback, which is called on each predefined gesture coordinate passed by the user.
onGestureFinish(gesture) => {}functionA callback, which is called when the user finishes a gesture. Receives the gesture key of the finished gesture.
onPanRelease() => {}functionCallback, when the user releases the finger. Receives no arguments.


GestureRecorder is a render props component. The child function has the form children({ gesture: [{ x: string, y: string }, { x: string, y: string }, ...], gestureDirectionHistory: [{ x: string, y: string }, { x: string, y: string }, ...], offset: { x: number, y: number } }).

gesture is an array of coordinates. They are generated based on the pointDistance prop of the component.

gestureDirectionHistory will tell you accordingly to gesture which direction the gesture is moving there. This might give somewhat unreliable data currently. A direction object looks like { x: "left", y: "up" }.

offset will artificially add an horizontal and vertical offset to the coordinates. This does not change the detection of the defined gesture at all. It's just a helper to use with the GesturePath component to paint the path where you actually draw. Check the GestureRecorder example screen for more details on this.

pointDistance20numberThe minimum distance between points that you want to be recorded. So default wise, every 20px (or more, usually depending on the phone hardware and the speed of the finger moving over the display) the component will add another point to the gesture array
onCapture() => {}functionA callback, which is called every time the component is adding a coordinate to the gesture array
onPanRelease(gesture) => {}functionCallback, when the user releases the finger. Receives the fully drawn gesture in form of a coordinate array.


GesturePath is a helper component, which paints a gesture visually in a container. The container should have position: absolute; set in its style property. { x, y } is a coordinate object. An array of coordinate objects must be passed to paint the gesture on the screen. This component should be only used in development to define and refine gestures.

path[]arrayAn array of coordinates to paint the gesture
slopRadius50numberThe radius around each coordinate, in which the user touch event will be associated with the gesture (or rather the radius of the circle being painted for each coordinate, as this whole component has no functionality really and is purely visual)
colorblackstringA string of a valid CSS color property


Paints a black, round indicator at the passed coordinate. The only useful situation is in development and you probably will use it like this, where coordinate is passed from the GestureDetector render props function:

{coordinate && <Cursor {...coordinate} />}

x0numberThe coordinate of the absolute center of the cursor relatively to the parent container.
y0numberThe coordinate of the absolute center of the cursor relatively to the parent container.
throttleMs50 in dev build, 25 in production buildnumberA performance optimization. Sets the time delay between each rerender of the repositioned cursor. You probably don't want to touch this.
