Dependency Management

Manage dependencies using the Dart Tooling MCP Server pub tool or standard CLI commands.

• Add package:checks as a dev_dependency using dart pub add dev:checks.
• Remove package:matcher if it is explicitly listed in the pubspec.yaml (note: it is often transitively included by package:test, which is fine).
• Import package:checks/checks.dart in all test files undergoing migration.

Syntax Migration Guidelines

Transition test assertions from the package:matcher syntax to the literate API provided by package:checks.

• Basic Equality: Replace expect(actual, equals(expected)) or expect(actual, expected) with check(actual).equals(expected).
