Custom Loading Animation

[RazvanRotaru]

The CircularProgessIndicator behaves weirdly on the web page, it stratches as much as it can. Moreover, the iOS standard loading widget is different from the one we use (for Android).

Given this problem, I believe a solution would be wrap it in a Center and a SizedBox and then use the new Widget in every scenario. In this case, it would be the perfect moment to create a loading animation.
