For some types it makes sense to distinguish between nullability as a property of including null and the declared nullability, such as for type-parameter types and FutureOr types. This CL introduces the separation between the two concepts. The plan is to use that when implementing FutureOrType.

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 [dartanalyzer][analyzercli] command-line tool to analyze their Dart code.
Integrators that want to write tools that analyze Dart code should use the [analyzer] package.
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.
