I'm super excited about this release. I've loved pattern matching and tuples for a long long time and I've wanted to bring them to Dart literally since before 1.0.
Also I'm so glad to see that updated long term vision for Dart. I've argued for a while now that it was more constrained than it should be and it was overlooked in a lot of use cases where it was actually a great language choice (i.e I write and run a bunch of cloud native backend services using Dart gRPC and Cloud Run and to me it's one of the best kept secrets about the language). Seeing that public commitment from the team is a big deal and much appreciated.
