The representation field of an inline class is not part of the generated code - it does not have a corresponding synthesized top-level methods like the other inline class members. Therefore, to support access to the representation field, a new `representationName` field is added to `InlineClass` that holds the name by which the representation field can be accessed. An access to the representation field is at runtime an access of the receiver itself. To show that the static type of the expression changes from the inline type of the receiver to the declared representation type, an `AsExpression` is inserted. Since this check is not needed at runtime, this node is marked with the new `isUnchecked` flag, that backends can use to skip the check.

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.
