containsEventHandlerAt method
Whether the game has an event-handling component at the given position.
Used by GameRenderBox for hit testing to determine if pointer events
should be consumed by the game or passed through to Flutter widgets
behind it.
The default returns true, meaning games that directly extend Game
will catch all events on their entire surface. FlameGame overrides this
to only report a hit when a component with event callbacks
(e.g. TapCallbacks) exists at the given position.
Implementation
bool containsEventHandlerAt(Vector2 position) => true;
