chore(markdown): remove dart:mirrors usage in tool/stats_lib.dart by kevmoo · Pull Request #2600 · dart-lang/tools

kevmoo · 2026-09-17T23:33:09Z

Replace ClosureMirror reflection (dart:mirrors) with Isolate.resolvePackageUriSync when resolving toolDir in pkgs/markdown/tool/stats_lib.dart.

dart:mirrors is now marked @deprecated on the Dart main channel (dart-lang/sdk#44489), which triggers deprecated_member_use during dart analyze --fatal-infos on dev/main SDKs.

Use Isolate.resolvePackageUriSync to locate the tool/ directory instead of ClosureMirror reflection.

Code Review

This pull request replaces the use of dart:mirrors with dart:isolate in stats_lib.dart to locate the "tool" directory, resolving the package URI statically instead of using reflection. The review feedback suggests avoiding the null assertion operator (!) on Isolate.resolvePackageUriSync to prevent uninformative null pointer exceptions, recommending a safer fallback with a descriptive error message instead.
