Dart 2.0 adds several instance members to a number of core library classes including Timer, Iterable, List, Set, Queue and Map. To manage the transition, migration stubs will be added to a number of core packages that implement these interfaces to ensure that these packages remain unbroken during the transition. These migration stubs can be replaced by full implementations at any time.
