system_info

Provides easy access to useful information about the system (architecture, bitness, kernel, memory, operating system, CPU, user).

Warning! Not tested on Mac OS X! Warning! Not tested on Linux ARM!

Basic examples:

if (SysInfo.operatingSystemName == "Ubuntu") {
  log.info("We love Ubuntu users");
}

if (SysInfo.userSpaceBitness == 32) {
  log.info("Dart VM runs as a 32-bit process");
}

Common information:

import "package:system_info/system_info.dart";

const int MEGABYTE = 1024 * 1024;

void main() {
  print("Kernel architecture     : ${SysInfo.kernelArchitecture}");
  print("Kernel bitness          : ${SysInfo.kernelBitness}");
  print("Kernel name             : ${SysInfo.kernelName}");
  print("Kernel version          : ${SysInfo.kernelVersion}");
  print("Operating system name   : ${SysInfo.operatingSystemName}");
  print("Operating system version: ${SysInfo.operatingSystemVersion}");
  print("User directory          : ${SysInfo.userDirectory}");
  print("User id                 : ${SysInfo.userId}");
  print("User name               : ${SysInfo.userName}");
  print("User space bitness      : ${SysInfo.userSpaceBitness}");
  var processors = SysInfo.processors;
  print("Number of processors    : ${processors.length}");
  for (var processor in processors) {
    print("  Architecture          : ${processor.architecture}");
    print("  Name                  : ${processor.name}");
    print("  Socket                : ${processor.socket}");
    print("  Vendor                : ${processor.vendor}");
  }
  print("Total physical memory   : ${SysInfo.getTotalPhysicalMemory() ~/ MEGABYTE} MB");
  print("Free physical memory    : ${SysInfo.getFreePhysicalMemory() ~/ MEGABYTE} MB");
  print("Total virtual memory    : ${SysInfo.getTotalVirtualMemory() ~/ MEGABYTE} MB");
  print("Free virtual memory     : ${SysInfo.getFreeVirtualMemory() ~/ MEGABYTE} MB");
  print("Virtual memory size     : ${SysInfo.getVirtualMemorySize() ~/ MEGABYTE} MB");
}
