This Week in Dart - Issue 6

Hello fellow Dartisans! Welcome to the sixth 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.


The next stable release of Dart, likely 2.18, will see the removal of the deprecated SCREAMING_CAPS constants in dart:io.

To prepare for this change, verify you aren't using the deprecated constants and use the corresponding lowerCamelCase constants instead.

Quotes and notes

I've fallen in love with Dart and wish I could use it (or the syntax at least) everywhere. All other syntaxes feel inferior to me now haha

Dart's async/isolates are the best thing about the language. Providing for decent concurrency based on Actor model is a huge win. Otherwise it's another simpler/better Java.
