react-native-gesture-handler isn't working (null is not an object)

React Native 升級爲0.60後，會出現null is not an object問題，如今的解決方案以下

Step 1 -- Disable autolinking for iOS and Not for Android

• module linked

react-native unlink react-native-gesture-handler --platform iOS
複製代碼

• module not linked

react-native link react-native-gesture-handler --platform android
複製代碼

Step 2 -- Create file in root project react-native.config.js

module.exports = {
  dependencies: {
    'react-native-gesture-handler': {
      platforms: {
        ios: null, // disable ios platform, other platforms will still autolink
      },
    },
  },
};
複製代碼

Step 3 -- Pod iOS and install jetify

For iOS

pod install on iOS folder

cd ios
pod install
複製代碼

For Android

1. npm install -save-dev jetifier or yarn add -D jetifier
2. add script in package.json file

"scripts": {
    ...
    "postinstall":"npx jetify"
  },
複製代碼

3. Run npm install or yarn;

Step 4 -- run your app as you like
