dart-migrate-to-checks-package

You can migrate Dart tests from package:matcher to package:checks using a migration workflow that translates expect/expectLater assertions, updates imports, handles deep equality, and verifies asynchronous patterns for type safety.

package:checks replaces legacy package:matcher assertions in Dart with a modern, type-safe API, reducing test brittleness and providing clearer, more precise failure diagnostics during test runs.

Yes, you can incrementally refactor Dart test suites to package:checks by applying partial migration strategies, enabling safe and repeatable refactors across multiple test files without a full immediate overhaul.

Migrating to package:checks handles deep equality by translating matcher logic to has-style checks, and addresses asynchronous patterns by converting expectLater usages to their Checks equivalents with built-in verification steps.

Yes, the Dart Checks migration workflow supports projects using package:test, directly translating both expect and expectLater assertion functions into their modern, type-safe package:checks equivalents.
