This week in Flutter #81: Dart 3 is coming

Soon Dart will drop support for unsound null safety. If you have been updating Dart versions and dependencies regularly, not much will change for you, probably.

In the article above, there is also a preview of a new feature that will be introduced during Flutter Forward: patterns. With patterns, you get multiple returns for a function, destructuring, and pattern matching over algebraic datatypes (switch over class types).

Much more will be possible, read more in the feature specification. It’s a long read, but worth it.
