system_info3

system_info3 provides easy access to essential system information, including details about your system's architecture, kernel, memory, operating system, CPU, and user environment.

With system_info3, you can easily retrieve key hardware and OS characteristics, such as:

• ✅ Kernel architecture
• ✅ Kernel bitness
• ✅ Kernel name
• ✅ Kernel version
• ✅ Operating system name
• ✅ Operating system version
• ✅ User directory
• ✅ User id
• ✅ User name
• ✅ User space bitness
• ✅ Physical memory and swap details
• ✅ CPU information

Usage

This package provides various system information like kernel details, operating system information, CPU specifications, and memory statistics. Below is a guide on how to use the package in different categories. Refer to the API documentation for more details on the available classes and methods.

1. Kernel Information

You can retrieve details about the system's kernel architecture, version, and other kernel-related information.

import 'package:system_info3/system_info3.dart';

void main() {
  print('Kernel architecture     : ${SysInfo.kernelArchitecture}');
  print('Raw Kernel architecture : ${SysInfo.rawKernelArchitecture}');
  print('Kernel bitness          : ${SysInfo.kernelBitness}');
  print('Kernel name             : ${SysInfo.kernelName}');
  print('Kernel version          : ${SysInfo.kernelVersion}');
}

Available Kernel Information:

• kernelArchitecture: The architecture of the kernel (e.g., x86_64, arm64).
• rawKernelArchitecture: The raw architecture of the kernel.
• kernelBitness: The bitness of the kernel (e.g., 32-bit or 64-bit).
• kernelName: The name of the kernel (e.g., Linux, Darwin).
• kernelVersion: The version of the kernel.

2. Operating System (OS) Information

You can get details about the operating system, user information, and the system's user environment.

import 'package:system_info3/system_info3.dart';

void main() {
  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}');
}

Available OS Information:

• operatingSystemName: The name of the operating system (e.g., Windows, Linux, macOS).
• operatingSystemVersion: The version of the operating system.
• userDirectory: The directory of the current user.
• userId: The ID of the current user.
• userName: The name of the current user.
• userSpaceBitness: The bitness of the user space (32-bit or 64-bit).

3. CPU Information

This section provides details about the CPU, such as the number of cores and their specific characteristics.

import 'package:system_info3/system_info3.dart';

void main() {
  final cores = SysInfo.cores;
  print('Number of cores    : ${cores.length}');
  for (final core in cores) {
    print('  Architecture          : ${core.architecture}');
    print('  Name                  : ${core.name}');
    print('  Socket                : ${core.socket}');
    print('  Vendor                : ${core.vendor}');
  }
}

Available CPU Information:

• cores: A list of CPU cores with details such as architecture, name, socket, and vendor.
  • architecture: The architecture of the core (e.g., x86_64, arm).
  • name: The name of the CPU core (e.g., Intel(R) Core(TM) i7-9700K).
  • socket: The socket number where the core resides.
  • vendor: The vendor of the CPU (e.g., Intel, AMD).

4. Memory/RAM Information

This section shows the total and free physical and virtual memory available on the system.

Note:: getFreePhysicalMemory() returns memory that is not in use but may not be immediately available for allocation. getAvailablePhysicalMemory() returns memory that can be reclaimed and is ready for use. This distinction is only relevant on Linux and Android. On MacOS and Windows the two values are the same.

import 'package:system_info3/system_info3.dart';

void main() {
  const int megaByte = 1024 * 1024;
  
  print('Total physical memory   : ${SysInfo.getTotalPhysicalMemory() ~/ megaByte} MB');
  print('Free physical memory    : ${SysInfo.getFreePhysicalMemory() ~/ megaByte} MB');
  print('Available physical memory: ${SysInfo.getAvailablePhysicalMemory() ~/ 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');
}

Available Memory Information:

• getTotalPhysicalMemory(): Returns the total physical memory in bytes.
• getFreePhysicalMemory(): Returns the free physical memory in bytes.
• getTotalVirtualMemory(): Returns the total virtual memory in bytes.
• getFreeVirtualMemory(): Returns the free virtual memory in bytes.
• getVirtualMemorySize(): Returns the virtual memory size in bytes.

Note: The memory values are returned in bytes. The example code converts them to megabytes for easier reading.
