Build me a simple Flutter app called Floating Character that works on mobile and web.

I want the main screen to show a cute character or mascot floating gently up and down on the screen, like it is hovering. Make it feel playful and polished, with a clean background and a smooth animation. The character should stay centered, and the app should look good on different screen sizes.

Please set up the app so it runs cleanly in Flutter, with the usual starter structure, and make the animation easy to tweak later. If you need to use any current Flutter best practices or look up the latest docs online, go ahead.

Keep it simple, but make it feel like a finished little demo app instead of a blank starter project. If it makes sense, add a basic home screen title or small text, but the floating character should be the main focus.
