system_info2 4.2.0

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

system_info2

A fork of system_info as the original maintainer no longer wishes to do so.

Thanks to onepub.dev for allowing me the time and resources to support this package.

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

system_info2 lets you discover specific hardware characteristics of the OS you are running on includeing:

• kernelArchitecture
• Kernel bitness
• Kernel name
• Kernel version
• Operating system name
• Operating system version
• User directory
• User id
• User name
• User space bitness

Basic examples:

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

Windows memory queries

Memory getters use local PowerShell Get-CimInstance queries, so WMIC is not required. Windows PowerShell (powershell.exe) must be on PATH, with the CimCmdlets module and local WMI/CIM service/providers available. Queries run without profiles or interactive prompts and do not require remote WinRM. Each synchronous getter starts a PowerShell process; these calls can be slow and should not be used in a tight polling loop or on a latency-sensitive UI path.

The public methods still return bytes. FreePhysicalMemory, FreeVirtualMemory, and TotalVirtualMemorySize from Win32_OperatingSystem are converted from KiB; Win32_ComputerSystem.TotalPhysicalMemory and the current Dart process's Win32_Process.VirtualSize are already bytes. Available and free physical memory retain the same Windows meaning. Virtual memory retains the WMI property semantics (it is not a measurement of the Dart heap).

If PowerShell/CIM fails, is blocked by policy, or returns missing/invalid data, memory getters now throw StateError instead of silently reporting zero. A valid zero result is still returned as zero. No execution-policy bypass or WMIC fallback is used. Other Windows information queries may still depend on WMIC.

Property definitions: operating system, computer system, and process.

Run dart test for fixture regression coverage. Tests marked for Windows or macOS also exercise the public API on those operating systems; skips on Linux do not constitute native-platform verification.
