flutter pub add checks基于插件公开信息、社区数据与项目使用情况整理的选型参考。
checks 包是一个 Dart 框架，旨在验证值是否符合预期条件，使开发者能够创建自定义断言和验证逻辑。它通过允许定义可重用的期望规则，为编写表达性强、可读性高的测试提供了灵活的基础。该包专为与测试工作流集成而设计，支持简单的值检查以及复杂的特定领域验证。在需要一致且可维护的断言模式的测试套件中，该包尤其有用。

Welcome! package:test is the standard testing library for Dart and
Flutter. If you have questions about Dart testing, please see the docs for
package:test. package:test_api and package:test_core
are implementation details and generally not user-facing.
package:checks is a relatively new library for expressing test
expectations. It's a more modern version of package:matcher and features a
literate API.
