A service that proxies between the Chrome debug protocol and the Dart VM service protocol.

11.0.2

• Implement _flutter.listViews extension method in dwds vm client.

11.0.1

• Make adding and removing breakpoints match VM behavior:
  • Allow adding existing breakpoints.

Breaking Changes:

• No longer use the BuildResult abstraction from package:build_daemon but require a similar abstraction provided by this package.
• AssetHandler has been renamed to AssetReader and no longer provides a generic resource handler. Specific methods for the required resources are now clearly defined. The new abstraction is now consumed through dwds.dart.
• BuildRunnerAssetHandler has been renamed to ProxyServerAssetReader and is now consumed through dwds.dart.
