Instance hash calculation on host and on target should produce same results(like when you use simarm_x64/gen_snapshot to produce arm snapshot). It was not producing same results because of how unboxed fields could be taking more than one word(on 32-bit arm they are taking two words). Hash calculation was done in terms of words so simarm_x64/gen_snapshot saw one word unboxed field, but same calculation saw two words. The fix is to pay special attention when iterating over unboxed field during hash calculation and accommodate host and target word size difference.

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).
