Information about the environment in which the current program is running.

Platform provides information such as the operating system,the hostname of the computer, the value of environment variables,the path to the running program,and other global properties of the program being run.

Get the URI of the current Dart script

Use thescript getter to get the URI to the currently runningDart script.

import 'dart:io' show Platform;void main() {  // Get the URI of the script being run.  var uri = Platform.script;  // Convert the URI to a path.  var path = uri.toFilePath();}

Get the value of an environment variable

Theenvironment getter returns a the names and values of environmentvariables in aMap that contains key-value pairs of strings. The Map isunmodifiable. This sample shows how to get the value of thePATHenvironment variable.

import 'dart:io' show Platform;void main() {  Map<String, String> envVars = Platform.environment;  print(envVars['PATH']);}

Determine the OS

You can get the name of the operating system as a string with theoperatingSystem getter. You can also use one of the static booleangetters:isMacOS,isLinux,isWindows, etc.

import 'dart:io' show Platform;void main() {  // Get the operating system as a string.  String os = Platform.operatingSystem;  // Or, use a predicate getter.  if (Platform.isMacOS) {    print('is a Mac');  } else {    print('is not a Mac');  }}
