Patterns may need to be visited twice during analysis: once to determine a type schema, and a second type to resolve the pattern match. Previously, the shared TypeAnalyzer had just a single `dispatchPattern` method, so it had to create temporary objects to record the structure of the patterns between the two visits. Now, there are two dispatch methods: `dispatchPatternSchema` and `dispatchPattern`. This avoids the creation of a bunch of temporary objects and makes the design much simpler.

Front end for Dart
This package provides a low-level API for use by compiler back ends that wish to implement the Dart language. It is intended for eventual use by dev_compiler, dart2js, and the Dart VM. In addition, it will share implementation details with the analyzer package--this will be accomplished by having the analyzer package import (and re-export) parts of this package's private implementation.
End-users should use the dart analyze
command-line tool to analyze their Dart code.
Integrators that want to write tools that analyze Dart code should use the analyzer package.
Note: A previous version of this package was published on pub.dev. It has now been marked DISCONTINUED as it is not intended for direct consumption, as per the notes above.
