Google software engineers have delivered Dart 2.6, an update to the open source programming language that provides the ability to create self-contained, native executables for the major desktop operating systems.
That capability comes from an extension to the Dart compiler set called
dart2native, which makes it possible to turn Dart files into self-contained executables holding ahead-of-time (AOT) compiled machine code. In other words, these executables will run on machines that don't have the Dart SDK installed.
dart2native, you can create tools for the command line on macOS, Windows, or Linux using Dart," said Michael Thomsen, a Google product manager, in a blog post.
Thomsen notes that Dart has supported AOT compilation to x86 and ARM executables for several years through Dart Native, but this capability has only been exposed through the Flutter SDK, Google's framework for creating native Android and iOS mobile applications using Dart.
Dart 2.6 also includes an improved version of
dart:ffi, which provides C interoperability, and a new language feature called extension methods.
In a post to Hacker News in 2011, he wrote, "The leaked Google doc's assertion that this is impossible and that a 'clean break' is required to make significant improvements is nonsense, a thin rationale for going it alone rather than cooperating fully."
"A Dart to JS compiler will never be 'decent' compared to having the Dart VM in the browser," Eich wrote. "Yet I guarantee you that Apple and Microsoft (and Opera and Mozilla, but the first two are enough) will never embed the Dart VM."
If developers were initially skeptical about Dart, they appear to be warming to it, thanks perhaps to Google's persistent promotion of Flutter and its promise that Flutter apps will run on the company's nascent Fuchsia operating system.
In GitHub's State of the Octoverse report, covering October 1, 2018 through September 30, 2019, the Microsoft-owned code hosting biz observed a surge in Dart interest. The language saw a 532 per cent increase during the report period, more than any other programming language and twice as much growth as the second-place rising star, Rust.
Dart still has a ways to go before it enters anyone's list of top ten programming languages – consultancy Redmonk ranked it #27 in July – but at least now its potential uses have moved beyond internal Google ad tech. ®
