This Week in Dart - Issue 3

Hello fellow Dartisans! Welcome to the fourth issue of This Week in Dart! This Week in Dart's aim is to be a useful collection of changes and news from across the Dart ecosystem and its surrounding community.

To contribute to this and future issues, feel free to contribute on GitHub or suggest content for next week on GitHub discussions.

To discuss this week's issue, feel free to join us on the Unofficial Dart Community Discord in the #this-week-in-dart channel.


It was brought to our attention by a Twitter post from @csells that Compiler Explorer by Matt Godbolt now supports compiling Dart code and showing the underlying assembly.

The support was initially added by Michael Debertol in commit 3f695c9 and supports some of the most recent releases of Dart, including those with and without null safety.

While not everyone needs to view the underlying assembly of their Dart code, and you could already do so locally, this addition greatly lowers the barrier to further exploration. Seeing how your code is compiled can help improve your understanding of the code and the Dart compiler itself, enabling you to potentially identify new functional or performance issues with either.

Project updates

Dart SDK updates

24 unique authors have contributed 79 commits to the Dart SDK in the past week.

The following are some handpicked, interesting changes:

Keep in mind, none of these changes are guaranteed to eventually land in a stable release.

Language updates and discussion

Work and discussion around the potential of adding patterns and records to Dart continues.

The most recent development has been a change to the pattern proposal's named field shorthand syntax to infer the field name instead of inferring the variable subpattern. See the Change named field shorthand syntax pull request on GitHub to review the proposed changes and provide feedback.

Package of the week

The package of the week is dart_frog!

package:dart_frog is a fast, minimalistic backend framework for Dart developed by Very Good Ventures.

According to their documentation:

Dart Frog is built on top of shelf and mason and is inspired by many tools including, next.js, and express.js.

The goal of Dart Frog is to help developers effectively build backends in Dart. Currently, Dart Frog is focused on optimizing the process of building backends which aggregate, compose, and normalize data from multiple sources.

Dart Frog provides a simple core with a small API surface area in order to reduce the learning curve and ramp-up time for developers. In addition, Dart Frog is intended to help Flutter/Dart developers maximize their productivity by having a unified tech stack that enables sharing tooling, models, and more!

The release of dart_frog and its corresponding packages is super exciting and marks the continued progress that the Dart ecosystem and community are making to again expand Dart beyond Flutter, particularly in the server space.

Dart's package ecosystem is growing fast, and we want to help foster that growth. If you know of any great open source projects, let us know by suggesting a package on GitHub discussions.

Quotes and notes

My fav of all time is [dart fix] @dart_lang which keeps the upgrade paths in that ecosystem incredibly smooth. As new language features and best practices roll out in new releases I run one command and it will rewrite my code for me to keep me on the happy path.

I am a proud @dart_lang fanboi. I just love working with it.
