Whats your perspective of the activity around the Dart VM? Is Google actively maintaining it? As a JS dev I always wrote it off as being a non-starter, but your project has intrigued me to taking a second look at the VM. Thanks!
Dart now targets the Web (two compilers - one for development, one for "production" - both transpiling to JS), the server (Dart server VM - fast native JIT VM), Mobile via flutter (support for AOT on iOS), and Fuchsia.

The changelog [1] always has a few entries for the Dart VM with each version, but it's quite clear from using it daily that much more is happening. Some notable recent improvements have been asynchronous breakpoints that are integrated in IntelliJ's debugger and some optimizations for sending messages across isolates.

Where did you get that info? I haven't seen it in the changelog. Is message passing using structured cloning?
