This CL adds a Node.toText method together with an AstPrinter. These facility and better toString implementation on AST nodes while allowing for toString independent printing of AST to use in testing. This also add support for an integrated toString of custom/internal nodes. Some work is still needed in bringing the toString implementation on all nodes to the old quality, and not all internal nodes have customized textual representations yet. This work is left for future CLs.

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.
