dart-migrate-to-checks-package

What problem does it solve?

Replaces legacy Dart test assertions that rely on package:matcher with the modern, type-safe package:checks API, reducing brittleness and improving failure diagnostics.

Core Features & Use Cases

• Import modernization: updates test imports from package:test to utilize package:checks scaffolding.
• Assertion translation: converts expect/expectLater and common matchers to Checks equivalents, including deep equality and has-style checks.
• Incremental migration: supports partial migration strategies and safe, repeatable refactors across multiple files.
• Use Case: migrate a large test suite from matcher-based assertions to a Checks-based pattern to gain stronger type-safety and clearer failures.

Quick Start

Run the migration workflow to replace legacy matcher assertions with Checks equivalents across all tests.
