scheduleFrame method Null safety

void scheduleFrame()

Requests that, at the next appropriate opportunity, the onBeginFrame and onDrawFrame callbacks be invoked.

Calling this function forwards the call to the same function on the PlatformDispatcher singleton, so instead of calling it here, you should consider calling it on WidgetsBinding.instance.platformDispatcher instead (or, when WidgetsBinding isn't available, on PlatformDispatcher.instance). The reason this function forwards to the PlatformDispatcher is to provide convenience for applications that only use a single main window.
