How to add codes in your Info.plist file using expo

Inside your app.plugin.js file, add the following code.

const { withInfoPlist } = require('expo/config-plugins');

module.exports = function myCustomExpoFunctionName(config) {
  config = withInfoPlist(config, (config) => {
    
    /* 
    Type 1
    Code to add in Info.plist file (String)
    */
    config.modResults['YourCustomMessageKey'] = 'Your custom message';
    /* 
    Type 1
    Result in Info.plist file as below
    <key>YourCustomMessageKey</key>
    <string>Your custom message</string>
    */

    /*
    Type 2
    Code to add in Info.plist file (Dictionary)
    */
    config.modResults.MyCustomDictionary = {
      MY_FIRST_KEY: 'My first value',
      MY_SECOND_KEY: 'My second value'
    };
    /*
    Type 2
    Result in Info.plist file as below
    <key>MyCustomDictionary</key>
    <dict>
      <key>MY_FIRST_KEY</key>
      <string>My first value</string>
      <key>MY_SECOND_KEY</key>
      <string>My second value</string>
    </dict>
    */

    /*
    Type 3
    Code to add in Info.plist file (Array)
    */
    config.modResults.MyCustomArray = ['My first value', 'My second value'];
    /*
    Type 3
    Result in Info.plist file as below
    <key>MyCustomArray</key>
    <array>
      <string>My first value</string>
      <string>My second value</string>
    </array>
    */



    return config;
  });
  return config;
};
