dart-migrate-to-checks-package

To migrate Dart test assertions, convert legacy expect and expectLater calls into type-safe package:checks syntax. This process systematically identifies matcher-based assertions and rewrites them into modern check patterns while preserving behavior.

Common migration pitfalls when modernizing Dart tests include handling collection equality, async throws, regex matching, nullable booleans, and map keys. Addressing these compatibility differences ensures correct assertion refactoring from package:matcher to package:checks.

Yes, package:checks provides better type safety, improved autocomplete, and enhanced test diagnostics compared to package:matcher. Adopting package:checks reduces migration effort and modernizes Dart test assertions with safer check syntax.

When converting to package:checks, handle async throws and collection equality by applying specific compatibility transformations. The migration addresses these edge cases to ensure legacy matcher assertions are rewritten into correct, type-safe check equivalents.

Yes, you can refactor expect calls by applying type-safe assertion transformations from package:matcher to package:checks. This migration systematically identifies legacy assertions and rewrites them into modern package:checks patterns while verifying the converted expectations.
