Serializing Let.fileOffset supports positions in stacktraces resulting from null aware expressions, like `if (o?.foo) ...` when `o` is `null`. Adding Function.futureValueType supports the proper backend implementation for the fix in https://dart-review.googlesource.com/c/sdk/+/181303 Closes #44654 TEST=existing Change-Id: Ie5939a248d3d8bf41388e8f435e4ba4195afeabd Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/182269 Commit-Queue: Johnni Winther <johnniwinther@google.com> Reviewed-by: Jens Johansen <jensj@google.com>
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.
