@expo/react-native-action-sheet

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.

Check out the example snack here!

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

iOS Only Props

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.

ActionSheetProvider Props

The following props can be set directly on the ActionSheetProvider

// 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!
}
