The many different entrypoints to the CFE have repeatedly shown problems with targets that do not support unevaluated constants being used without providing an environment. Making the targets opt-in to supporting unevaluated constants will give the users of CFE early notice that CFE is used inconsistently (as opposed to the backends failing when they happen to see an UnevaluatedConstant node that they don't support).

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.
