title: Cannot do new Image Asset in res folder
body: <p>I want to do a new Image Asset in my res folder in my flutter project, to change the layout of my app icon. However when i right click on the res folder and chose New -> 'Image Asset' is no longer an option in my Android Studio... Anyone who knows how to fix this? I've been able to do it before. I've updated the Flutter plugin, but that didn't make any difference. </p>
