[vm/service] Shutdown service isolate if its main errored If main function throws an error it might leave service isolate in an inconsitent state and it does make sense to keep the isolate running we might even dead lock trying to shut it down later (e.g. it might have failed to create native port). Flutter engine has a unit test which beings startup sequence for service isolate and then quickly shutdowns VM - in this case vmservice main throws and error trying to create native port. If we mark service isolate as running at this state we will end up deadlocking in shutdown sequence because main thread can't send exit message to the service isolate (as we failed to create a port).

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.
