serve method
Start serve with numberOfIsolates
(default: numberOfProcessors).
Await until server shutdown.
Implementation
Future<void> serve({int? numberOfIsolates}) async {
final total = numberOfIsolates ?? Platform.numberOfProcessors;
for (var n = 1; n < total; n += 1) {
await Isolate.spawn(_serve, this);
}
await _serve(this);
}
