During constant evaluation, unused arguments to a const constructor are thrown away after evaluation, since their values do not affect the resulting instance constant. If such an unused argument ends up unevaluated, any errors that would arise in the final evaluation are not reported. This CL adds space in the Kernel AST for saving these unevaluated expressions so they can be checked during final constant evaluation. Even though this is an incompatible change, no update is needed to the VM code (except for the version bump), since the VM does not support InstanceCreation nodes in the first place.

Dart Kernel
Dart Kernel is a small high-level language derived from Dart. It is designed for use as an intermediate format for whole-program analysis and transformations, and to be consumed by codegen and execution backends.
The kernel language has an in-memory representation in Dart and can be serialized as binary or text.
Both the kernel language and its implementations are unstable and are under development.
This package contains the Dart part of the implementation and contains:
- A transformable IR for the kernel language
- Serialization of kernel code
Note: The APIs in this package are in an early state; developers should be careful about depending on this package. In particular, there is no semver contract for release versions of this package. Please depend directly on individual versions.
See ast.dart for the in-memory IR, or binary.md for a description of the binary format. For now, the textual format is very ad-hoc and cannot be parsed back in.
