Problem to solve

Often, a game needs some time to load its resources/assets. In this case some kind of a loading screen is necessary.

Currently, the only support from Flame for this functionality comes from the loadingBuilder parameter of the GameWidget. However, this solution may be insufficient for the following reasons:

• it is non-trivial to pass the loading progress from the game to the loading widget;
• since the loading page is inherently dynamic, one may want to use Flame's rendering for it instead of relying on Flutter animations or custom painters;
• it is unclear how to use the loadingBuilder (or whether it is even possible) to show loading progress when loading internal components, such as a particular level within the game.

Proposal

How exactly to solve this is TBD. Should this be a specialized Route within the Navigator? Or a mixin to a page? Or a page wrapper? Or a child?

I'd be interested to hear how people solve this problem right now.
