Should we have animation logo ?

This idea is being inspired by the create-react-app template, where it creates a rotation animation of react logo in the center using CSS. It also contains a sample use case of media queries in CSS. We can have a simple flutter logo with fade-in/fade-out animation in the center using in build animation widgets.

Start by inspecting the template's current entry point and widget structure, since no file or test is named. Confirm the desired centered Flutter logo animation and the accompanying media-query example; done when the template demonstrates the requested examples.
