π» Installation
npm install @devvie/bottom-sheet
or
yarn add @devvie/bottom-sheet
π± Minimal Usage
Opening and closing the bottom sheet is done imperatively, so just pass a ref
to the bottom sheet and call the open
or close
methods via the ref
instance to open and close the bottom sheet respectively.
Examples
Typescript
import React, { useRef } from 'react';
import BottomSheet, { BottomSheetMethods } from '@devvie/bottom-sheet';
import { Button } from 'react-native';
const App = () => {
const sheetRef = useRef<BottomSheetMethods>(null);
return (
<Button title="Open" onPress={() => sheetRef.current.open()} />
<BottomSheet ref={sheetRef}>
<Text>
The smart π, tiny π¦, and flexible π bottom sheet your app craves π
</Text>
</BottomSheet>
);
};
export default App;
Javascript
import React, { useRef } from 'react';
import BottomSheet, { BottomSheetMethods } from '@devvie/bottom-sheet';
import { Button } from 'react-native';
const App = () => {
const sheetRef = useRef(null);
return (
<Button title="Open" onPress={() => sheetRef.current.open()} />
<BottomSheet ref={sheetRef}>
<Text>
The smart π, tiny π¦, and flexible π bottom sheet your app craves π
</Text>
</BottomSheet>
);
};
β Warning
The bottom sheet component uses and handles pan gestures internally, so to avoid scroll/pan misbehavior with its container, DO NOT put it inside a container that supports panning e.g ScrollView
. You can always put it just next to the ScrollView
and use React Fragment
or a View
to wrap them and everything should be okay.

<BottomSheet>
...
</BottomSheet>
</ScrollView>
