Use `pub get` to generate `.dart_tool/package_config.json` on gclient sync. All pkg/ (and a few third_party) packages that are developed inside the sdk repo are included in the workspace from the root `pubspec.yaml`. All dependencies that are pulled in via DEPS are added as path dependencies via `dependency_overrides` in the root `pubspec.yaml`. Bug: https://github.com/dart-lang/sdk/issues/56220 Change-Id: I38c12b608c68da54c57821116cf9aa6696936746 Tested: relies on CQ of existing tests.

☠☠ Warning: This package is experimental and may be removed in a future version of Dart. ☠☠
This package is not intended for wide use. It provides a temporary API to solve the problem: "Given an object some generic type A, how do I construct an instance of generic type B with the same type argument(s)?"
This is necessary in a few rare places in order to migrate existing code to Dart 2's stronger type system. Eventually, the hope is to have direct language support for solving this problem but we don't have time to get that into 2.0, so this package is provided as a temporary workaround.
We will very likely remove support for this in a later version of Dart. Please avoid using this if you can. If you feel you do need to use it, please reach out to @munificent or @leafpetersen and let us know.
