title: React Native: Is there any way to check if the file exists in android_asset folder or not?
body: <p>I need to check file existence in the folder like this:</p>
  
  <pre><code>file:///android_asset/contents/my.html
  </code></pre>
  
  <p>I've tried to use react-native-filesystem plugin</p>
  
  <pre><code>componentWillMount () {
      async function checkIfFileExists() {
        const fileExists = await FileSystem.fileExists('file:///android_asset/contents/my.html')
        console.log(`file exists: ${fileExists}`)
      }
  }
  </code></pre>
  
  <p>I'm sure that my.html file is there, but I get false in fileExists.
  Does anybody know how to check it properly?</p>
