    Reanimated Bottom Sheet

    Highly configurable component imitating native bottom sheet behavior, with fully native 60 FPS animations!

    Built from scratch with react-native-gesture-handler and react-native-reanimated.

    Usable with Expo with no extra native dependencies!


    Open a Terminal in the project root and run:

    yarn add reanimated-bottom-sheet

    Or if you use npm:

    npm install reanimated-bottom-sheet

    Now we need to install react-native-gesture-handler and react-native-reanimated.

    If you are using Expo, to ensure that you get the compatible versions of the libraries, run:

    expo install react-native-gesture-handler react-native-reanimated

    If you are not using Expo, run the following:

    yarn add react-native-reanimated react-native-gesture-handler

    Or if you use npm:

    npm install react-native-reanimated react-native-gesture-handler

    We're done! Now you can build and run the app on your device/simulator.


    import * as React from 'react';
    import { StyleSheet, Text, View, Button } from 'react-native';
    import Animated from 'react-native-reanimated';
    import BottomSheet from 'reanimated-bottom-sheet';
    export default function App() {
      const renderContent = () => (
            backgroundColor: 'white',
            padding: 16,
            height: 450,
          <Text>Swipe down to close</Text>
      const sheetRef = React.useRef(null);
      return (
              flex: 1,
              backgroundColor: 'papayawhip',
              alignItems: 'center',
              justifyContent: 'center',
              title="Open Bottom Sheet"
              onPress={() => sheetRef.current.snapTo(0)}
            snapPoints={[450, 300, 0]}


    name required default description
    snapPoints yes E.g. [300, 200, 0]. Points for snapping of bottom sheet coomponent. They define distance from bottom of the screen. Might be number or percent (as string e.g. '20%') for points or percents of screen height from bottom. Note: Array values must be in descending order.
    initialSnap no 0 Determines initial snap point of bottom sheet. The value is the index from snapPoints.
    renderContent no Method for rendering scrollable content of bottom sheet.
    renderHeader no Method for rendering non-scrollable header of bottom sheet.
    enabledGestureInteraction no true Defines if bottom sheet could be scrollable by gesture.
    enabledHeaderGestureInteraction no true Defines if bottom sheet header could be scrollable by gesture.
    enabledContentGestureInteraction no true Defines if bottom sheet content could be scrollable by gesture.
    enabledContentTapInteraction no true Defines whether bottom sheet content could be tapped. Note: If you use Touchable* components inside your renderContent, you'll have to switch this to false to make handlers like onPress work. (See this comment.)
    enabledManualSnapping no true If false blocks snapping using snapTo method.
    enabledBottomClamp no false If true block movement is clamped from bottom to minimal snapPoint.
    enabledBottomInitialAnimation no false If true sheet will grows up from bottom to initial snapPoint.
    enabledInnerScrolling no true Defines whether it's possible to scroll inner content of bottom sheet.
    callbackNode no reanimated node which holds position of bottom sheet, where 0 it the highest snap point and 1 is the lowest.
    contentPosition no reanimated node which holds position of bottom sheet's content (in dp)
    headerPosition no reanimated node which holds position of bottom sheet's header (in dp)
    overdragResistanceFactor no 0 `Defines how violently sheet has to stopped while overdragging. 0 means no overdrag
    springConfig no { } Overrides config for spring animation
    innerGestureHandlerRefs no Refs for gesture handlers used for building bottom sheet. The array consists fo three refs. The first for PanGH used for inner content scrolling. The second for PanGH used for header. The third for TapGH used for stopping scrolling the content.
    simultaneousHandlers no Accepts a react ref object or an array of refs to handler components.
    onOpenStart no Accepts a function to be called when the bottom sheet starts to open.
    onOpenEnd no Accepts a function to be called when the bottom sheet is almost fully openned.
    onCloseStart no Accepts a function to be called when the bottom sheet starts to close.
    onCloseEnd no Accepts a function to be called when the bottom sheet is almost closing.
    callbackThreshold no 0.01 Accepts a float value from 0 to 1 indicating the percentage (of the gesture movement) when the callbacks are gonna be called.
    borderRadius no Border radius of content wrapper (excluding header)



    Imperative method on for snapping to snap point in given index. E.g.

    // Snap to the snap point at index 0 (e.g. 450 in [450, 300, 0])

    Here this.bottomSheetRef refers to the ref passed to the BottomSheet component.


    More complex examples can be found in the Example folder. To view the examples in the Expo app, open a Terminal and run:

    yarn prepare
    cd Example
    expo start

    The example app is also available on Expo.


    It's not finished and some work has to be done yet.

    1. Play with magic config values
    2. Horizontal mode
    3. Deal with GH in inner scrollView
    4. Cleanup code (e.g. measuring of components)
