I have some troubles in my applications since I'm using different animated widget in combination of Future Builder (I think this is the problem).
For example when I perform a navigation to another page and in this page I retrieve data with future builder, the page transitions lag. This is an example:
As you can see the animation is lagging at the end. But I'm not sure that is a problem with Future Builder and the transitions.
This example was made on a release application on iOS, so not in debug mode.
