Platform class abstract

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 so on.

Get the URI to the current Dart script

Use the script getter to get the URI to the currently running Dart 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

The environment getter returns a the names and values of environment variables in a Map that contains key-value pairs of strings. The Map is unmodifiable. This sample shows how to get the value of the PATH environment 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 the operatingSystem getter. You can also use one of the static boolean getters: isMacOS, isLinux, and isWindows.

import 'dart:io' show Platform, stdout;

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');
  }
}
