# SysInfo

The SysInfo class is the core class that provides all the details of the hardware you are running on.

See the individual pages listed in the TOC for details.

### Example:

```dart
import "package:system_info2/system_info2.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");
}
```
