ready method
A future that completes when the game is fully ready to start.
The GameWidget awaits this future after the game has been loaded and
mounted, before the game is shown and the first update tick runs. By
default it completes immediately; FlameGame overrides this to wait
until the whole initial component tree has been loaded and mounted.
Since this future is awaited on the startup critical path, an override that never completes keeps the game on the loading widget forever.
Implementation
Future<void> ready() async {}
