title: Android 'react-native-gesture-handler' error
body: <p>When I follow the instruction by the react-navigation website : <a href="https://reactnavigation.org/docs/en/getting-started.html" rel="nofollow noreferrer">https://reactnavigation.org/docs/en/getting-started.html</a>.</p>
  
  <p>react-native link react-native-gesture-handler</p>
  
  <p>and then change the MainActivity.java like it asks.</p>
  
  <p>Then run react-native run-android, and error pop up :
  error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually:</p>
  
  <p>react-native-gesture-handler (to unlink run: "react-native unlink react-native-gesture-handler")
  This is likely happening when upgrading React Native from below 0.60 to 0.60 or above. Going forward, you can unlink this dependency via "react-native unlink " and it will be included in your app automatically. If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.
  my react-native version :
  react-native-cli: 2.0.1
  react-native: 0.60.0</p>
  
  <p>However, when I follow the instruction, to unlink the library
  use : react-native unlink react-native-gesture-handler</p>
  
  <p>The app successfully built, but now it pops up another error in the app :
  null is not an object (evaluating 'rngesturehandlermodule.direction')</p>
  
  <p>I tried a lot of solution in a lot of websites, like
  <a href="https://stackoverflow.com/questions/52861437/undefined-is-not-an-object-evaluating-rngesturehandlermodule-state">undefined is not an object (evaluating &#39;RNGestureHandlerModule.State&#39;</a></p>
  
  <p>non of them is working for me</p>
