Jens Johansen 5eff2a0374 Split CanonicalNameError, no warning if CanonicalNameSdkError
Prior to this CL, we would issue a warning whenever a CanonicalNameError
was encountered.
This is in principal a good thing, but because we currently have no way
to detect if the sdk we get is the one we expect
(by any other measure than when it issues a CanonicalNameError) we often
issue these warnings for no "real reason" whenever, for instance,
the flutter sdk changes.

This CL splits the CanonicalNameError in two such that errors with
references to the sdk ("dart:" libraries) issue CanonicalNameSdkError
instead, an we then handle that differently. Namely we silently ignore
the error (i.e. don't issue a warning) and just don't initialize from
dill.

This should remedy the situation and be strictly better than to always
swallow CanonicalNameErrors.

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.
