-/// This library is capable of producing linked summaries from unlinked
-/// ones (or prelinked ones). It functions by building a miniature
-/// element model to represent the contents of the summaries, and then
-/// scanning the element model to gather linked information and adding
-/// it to the summary data structures.
-///
-/// The reason we use a miniature element model to do the linking
-/// (rather than resynthesizing the full element model from the
-/// summaries) is that it is expected that we will only need to
-/// traverse a small subset of the element properties in order to link.
-/// Resynthesizing only those properties that we need should save
-/// substantial CPU time.
-///
-/// The element model implements the same interfaces as the full
-/// element model, so we can re-use code elsewhere in the analysis
-/// engine to do the linking. However, only a small subset of the
-/// methods and getters defined in the full element model are
-/// implemented here. To avoid static warnings, each element model
-/// class contains an implementation of `noSuchMethod`.
-///
-/// The miniature element model follows the following design
-/// principles:
-///
-/// - With few exceptions, resynthesis is done incrementally on demand,
-/// so that we don't pay the cost of resynthesizing elements (or
-/// properties of elements) that aren't referenced from a part of the
-/// element model that is relevant to linking.
-///
-/// - Computation of values in the miniature element model is similar
-/// to the task model, but much lighter weight. Instead of declaring
-/// tasks and their relationships using classes, each task is simply
-/// a method (frequently a getter) that computes a value. Instead of
-/// using a general purpose cache, values are cached by the methods
-/// themselves in private fields (with `null` typically representing
-/// "not yet cached").
-///
-/// - No attempt is made to detect cyclic dependencies due to bugs in
-/// the analyzer. This saves time because dependency evaluation
-/// doesn't have to be a separate step from evaluating a value; we
-/// can simply call the getter.
-///
-/// - However, for cases where cyclic dependencies may occur in the
-/// absence of analyzer bugs (e.g. because of errors in the code
-/// being analyzed, or cycles between top level and static variables
-/// undergoing type inference), we do precompute dependencies, and we
-/// use Tarjan's strongly connected components algorithm to detect
-/// cycles.
-///
-/// - As much as possible, bookkeeping data is pointed to directly by
-/// the element objects, rather than being stored in maps.
-///
-/// - Where possible, we favor method dispatch instead of "is" and "as"
-/// checks. E.g. see [ReferenceableElementForLink.asConstructor].

+- Added `HeapSnapshotGraph` class which parses the binary events posted to the
+ `HeapSnapshot` stream after a `requestHeapSnapshot` invocation.
+- Fixed issue where listening to `EventStream.kHeapSnapshot` and calling
+ `requestHeapSnapshot` would throw an exception.
+
## 2.0.0
- **breaking**: VM service objects which have fields now have constructors with
named parameters for each field. Required fields are annotated with `@required`.
