[ CLI ] Start DDS instance if VM service URI passed to dart devtools doesn't have a DDS connection This is can happen if a Dart or Flutter application is started in a non-standard way (e.g., not through the `dart` or `flutter` CLI tooling). Developers using custom embedders need to use `dart devtools` to start a DevTools instance, so it's a good opportunity to check for a DDS instance and launch DDS for the target application if one isn't found.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
