![]() This is a breaking change. https://github.com/dart-lang/sdk/issues/40483 The Process class will now throw a StateError if the process is detached upon accessing the exitCode getter. It now also throws when not connected to the child process's stdio upon accessing the stdin, stdout, and stderr getters. Previously these getters would all return null. The getters in question are meaningless for detached processes and there is no reason to use them in that case. To provide a better experience when Dart becomes null-safe, these getters are changed to throw and never return null, which avoids all legitimate uses of the getters from needing a null check that will never fail. The NNBD migration required making subtle changes to some dart:io semantics in order to provide a better API. This change backports one of these semantic changes to the unmigrated SDK so any issues can be discovered now instead of blocking the future SDK unfork.

Dart
A client-optimized language for fast apps on any platform
Dart is:
-
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app
-
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
-
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
-
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
License & patents
Dart is free and open source.
