React Native Action Sheet is a cross-platform React Native component that uses the native UIActionSheet on iOS and a pure JS implementation on Android.

Installation
npm install @expo/react-native-action-sheet
or

yarn add @expo/react-native-action-sheet
A basic ActionSheet Setup

1. Wrap your top-level component with <ActionSheetProvider />
   ReactNativeActionSheet uses React context to allow your components to invoke the menu. This means your app needs to be wrapped with the ActionSheetProvider component first.

import { ActionSheetProvider } from '@expo/react-native-action-sheet';

export default function AppContainer() {
return (
<ActionSheetProvider>
<App />
</ActionSheetProvider>
);
} 2. Call the showActionSheetWithOptions method with a hook or a higher order component.
// Using the provided hook
import { useActionSheet } from '@expo/react-native-action-sheet';

export default Menu() {
const { showActionSheetWithOptions } = useActionSheet();

const onPress = () => {
const options = ['Delete', 'Save', 'Cancel'];
const destructiveButtonIndex = 0;
const cancelButtonIndex = 2;

    showActionSheetWithOptions({
      options,
      cancelButtonIndex,
      destructiveButtonIndex
    }, (selectedIndex: number) => {
      switch (selectedIndex) {
        case 1:
          // Save
          break;

        case destructiveButtonIndex:
          // Delete
          break;

        case cancelButtonIndex:
          // Canceled
      }});

}

return (
<Button title="Menu" onPress={onPress}/>
)
};
Alternatively, any component can use the higher order component to access the context and pass the showActionSheetWithOptions as a prop.

// Using a Higher Order Component to wrap your component
import { connectActionSheet } from '@expo/react-native-action-sheet';

function Menu({ showActionSheetWithOptions }) {
/_ ... _/
}

export default connectActionSheet(Menu);
Menu component can now access the actionSheet prop as showActionSheetWithOptions.

Options
The goal of this library is to mimic the native iOS and Android ActionSheets as closely as possible.

This library can also be used in the browser with Expo for web.

Universal Props
Name Type Description
options array of strings A list of button titles (required)
cancelButtonIndex number Index of cancel button in options
cancelButtonTintColor string Color used for the change the text color of the cancel button
destructiveButtonIndex number or array of numbers Indices of destructive buttons in options
title string Title to show above the action sheet
message string Message to show below the title
tintColor string Color used for non-destructive button titles
disabledButtonIndices array of numbers Indices of disabled buttons in options
iOS Only Props
Name Type Description
anchor number iPad only option that allows for docking the action sheet to a node. See ShowActionSheetButton.tsx for an example on how to implement this.
userInterfaceStyle string The interface style used for the action sheet, can be set to light or dark, otherwise the default system style will be used.
Custom Action Sheet Only (Android/Web) Props
The below props allow modification of the Android ActionSheet. They have no effect on the look on iOS as the native iOS Action Sheet does not have options for modifying these options.

Name Type Description
icons array of required images or icons Show icons to go along with each option. If image source paths are provided via require, images will be rendered for you. Alternatively, you can provide an array of elements such as vector icons, pre-rendered Images, etc.
tintIcons boolean Icons by default will be tinted to match the text color. When set to false, the icons will be the color of the source image. This is useful if you want to use multicolor icons. If you provide your own nodes/pre-rendered icons rather than required images in the icons array, you will need to tint them appropriately before providing them in the array of icons; tintColor will not be applied to icons unless they are images from a required source.
textStyle TextStyle Apply any text style props to the options. If the tintColor option is provided, it takes precedence over a color text style prop.
titleTextStyle TextStyle Apply any text style props to the title if present.
messageTextStyle TextStyle Apply any text style props to the message if present.
autoFocus boolean If true, this will give the first option screen reader focus automatically when the action sheet becomes visible. On iOS, this is the default behavior of the native action sheet.
showSeparators boolean Show separators between items. On iOS, separators always show so this prop has no effect.
containerStyle ViewStyle Apply any view style props to the container rather than use the default look (e.g. dark mode).
separatorStyle ViewStyle Modify the look of the separators rather than use the default look.
useModal boolean Defaults to false (true if autoFocus is also true) Wraps the ActionSheet with a Modal, in order to show in front of other Modals that were already opened (issue reference).
destructiveColor string Modify color for text of destructive option. Defaults to #d32f2f.
ActionSheetProvider Props
The following props can be set directly on the ActionSheetProvider

Name Type Description
useCustomActionSheet boolean iOS only prop that uses the custom pure JS action sheet (Android/Web version) instead of the native ActionSheetIOS component. Defaults to false.
useNativeDriver boolean Windows only option that provides the option to disable the native animation driver for React Native Windows projects targeting Windows 10 Version-1809 ; Build-10.0.17763.0 and earlier. useNativeDriver is supported in Version-1903 and later so if your project is targeting that, you don't need to set this prop.
// example of using useCustomActionSheet on iOS
export default function AppContainer() {
return (
<ActionSheetProvider useCustomActionSheet={true}>
<App />
</ActionSheetProvider>
);
}
Callback
The second parameter of the showActionSheetWithOptions function is a callback for when a button is selected. The callback takes a single argument which will be the zero-based index of the pressed option. You can check the value against your cancelButtonIndex to determine if the action was cancelled or not.

function onButtonPress(selectedIndex: number) {
// handle it!
}
