Several people have experienced build issues traced back to target `//utils/dartanalyzer:generate_summary_strong`. The issue is triggered by the sdk_hash changing with an old kernel-service snapshot in the out/ folder. `generate_summary_strong` uses but does not explicitly depend on the kernel-service, causing the outdated dependency. This then causes 'Unexpected Kernel SDK Version' when the new dart binary tried to load the old kernel-service snapshot. Tested: 1. Clean build of create_sdk at HEAD. 2. Empty `git commit --amend` to modify commit and thus sdk hash. 3. Rebuild of create_sdk (which failed before).

Dart
A client-optimized language for fast apps on any platform
Dart is:
-
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app
-
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web
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).
