Question

How can I find the OS's architecture using Dart on the server side?

Answer 1

You can use the Platform class:

import 'dart:io';

main() {
  print(Platform.operatingSystem);
  print(Platform.numberOfProcessors);
}

If the Platform class is not enough, you could also create a new process and execute some command to see if it returns something meaningful (like execute ps to retrieve processes, etc.).
