Dart is an approachable, portable, and productive language for high-quality apps on any platform. TC52 continues to work on new releases (Dart 3 and above) making notable changes, bug fixes and incremental improvements. A new language feature “sound null safety” was introduced in Dart 2.12. Null safety is a major productivity feature intended to help you avoid null errors. The committee plans to work on updating the formal specification to match those significant changes. Additional information is available.
