OnRestartCallback typedef

OnRestartCallback = void Function()

Called when the tester taps "Restart now" on showRestartBanner. The SDK deliberately doesn't restart the app itself — Flutter has no built-in "restart the process" API, and the right mechanism varies by app (a Restart.restartApp()-style package, popping back to a root widget and rebuilding it, or simply asking the user to close and reopen manually). Provide whichever of those your app already uses.
