This flag used to be used for field promotion (to ensure that lowered late fields are promotable, provided that they are private and final and don't have a name that conflicts with something else non-promotable). However, as of https://dart-review.googlesource.com/c/sdk/+/330168, the logic for determining when a Procedure is promotable now operates solely by checking for all the conditions that prevent promotability. Lowered late fields are now promotable because there is no reason for them not to be.

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.
