Hello Friends,

Welcome To Infinitbility!

In this tutorial, we create react native app with share funtionallity of image, file, and text using react native share example.

This Article Part of React Native Tutorial Series want to start from scrach follow below link

https://infinitbility.github.io/react-native/table-of-contents

Installing

Install react native share package.

  • for npm users
npm install react-native-share --save
  • for yarn users
yarn add react-native-share

*** Install dependencies ( only for iOS )***

  • install pod
cd ios && pod install

*** If you want share base64 image on your application ***

  • add line on your AndroidManifest.xml
<!-- required for react-native-share base64 sharing -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

sometime auto link not work for any reason, you can still run below command to link lib.

npx react-native link react-native-share

*** LSApplicationQueriesSchemes (iOS only) ***

If you want to share Whatsapp, Mailto or some applications on iOS, you should write LSApplicationQueriesSchemes in info.plist:


  <key>LSApplicationQueriesSchemes</key>
  <array>
    <string>whatsapp</string>
    <string>mailto</string>
    <string>instagram</string>
    <string>instagram-stories</string>
  </array>

Also, to save photos your gallery you will need setting the following permission on your Info.plist


  <key>NSPhotoLibraryAddUsageDescription</key>
  <string>$(PRODUCT_NAME) wants to save photos</string>

( Now we are not adding Manual Install, if you facing any issue or want a tutorial to add your comment below )

Issue & Solution

when you want to install react native share example & you got Error like below

  1. ReferenceError: Can’t find variable: string

search code on your app

const [packageSearch, setPackageSearch] = useState<string>('');
const [recipient, setRecipient] = useState<string>('');
const [result, setResult] = useState<string>('');

To


const [packageSearch, setPackageSearch] = useState('');
const [recipient, setRecipient] = useState('');
const [result, setResult] = useState('');
