Circular loading widget persists if initial data doesn't fill the screen

[jacksilver2]

This is a very useful implementation of infinite scrolling and your videos are great, however I found that if there isn't enough data to fill the screen (i.e no need for scrolling) then the loading widget appears at the bottom and never goes away. Is there a way to fix this? This happens, for example if we choose 10 in the following line (in models.dart).

return _getExampleServerData(10).then((postsData)
