A cross-platform ActionSheet for React Native

react-native-action-sheet

ActionSheet is a cross-platform React Native component that uses the native UIActionSheet on iOS and a JS implementation on Android. Almost a drop in replacement for ActionSheetIOS except it cannot be called statically.

iOS Android Web

Installation

$ npm install @expo/react-native-action-sheet -S

or

$ yarn add @expo/react-native-action-sheet

A basic ActionSheet Setup

1. Wrap your top-level component with <ActionSheetProvider />

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

class AppContainer extends React.Component {
  render() {
    return (
      <ActionSheetProvider>
        <ConnectedApp />
      </ActionSheetProvider>
    );
  }
}

2. Connect your component which uses showActionSheetWithOptions.

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

class App extends React.Component {
  /* ... */
}

const ConnectedApp = connectActionSheet(App)

export default ConnectedApp

App component can access the actionSheet method as this.props.showActionSheetWithOptions

_onOpenActionSheet = () => {
  // Same interface as https://facebook.github.io/react-native/docs/actionsheetios.html
  const options = ['Delete', 'Save', 'Cancel'];
  const destructiveButtonIndex = 0;
  const cancelButtonIndex = 2;

  this.props.showActionSheetWithOptions(
    {
      options,
      cancelButtonIndex,
      destructiveButtonIndex,
    },
    buttonIndex => {
      // Do something here depending on the button index selected
    },
  );
};

You can use a hook instead of the higher order component if you are on React 16.8 or newer.

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

export default function App () {
  const { showActionSheetWithOptions } = useActionSheet();
  /* ... */
}

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

The same options available on React Native’s ActionSheetIOS component exist for both iOS and Android in this library.

iOS Only Props

Name Type Required Default
anchor number No

anchor (optional)

iPad only option that allows for docking the action sheet to a node. See ShowActionSheetButton.tsx for an example on how to implement this.

Android/Web-Only 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 Required Default
icons array of required images or icons No
tintIcons boolean No true
textStyle TextStyle No
titleTextStyle TextStyle No
messageTextStyle TextStyle No
autoFocus boolean No false
showSeparators boolean No false
containerStyle ViewStyle No
separatorStyle ViewStyle No
useModal boolean No false
destructiveColor string No #d32f2f

icons (optional)

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 (optional)

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 (optional)

Apply any text style props to the options. If the tintColor option is provided, it takes precedence over a color text style prop.

titleTextStyle (optional)

Apply any text style props to the title if present.

messageTextStyle (optional)

Apply any text style props to the message if present.

autoFocus: (optional)

If true, 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: (optional)

Show separators between items. On iOS, separators always show so this prop has no effect.

containerStyle: (optional)

Apply any view style props to the container rather than use the default look (e.g. dark mode).

separatorStyle: (optional)

Modify the look of the separators rather than use the default look.

useModal: (optional)

Wrap the ActionSheet with a Modal, in order to show in front of other Modals that were already opened (issue reference).

destructiveColor: (optional)

Modify color for text of destructive option.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
