title: How to create APK Expansion Files for assets within flutter
body: <p>I have created a flutter app with video assets which are about 450mb in size. I have published the app successfully in the Apple appstore. But Google Play does not accept my APK as it is over the limit of 200mb. I tried to go with the approach of creating APK expansion files as the recommended workflow. I have read all available Android documention about expansion files but I still can not figure out how to implement them with flutter.</p>
  
  <p>How do you implement and access assets within APK expansion files in a flutter app?</p>
