flutter pub add fake_async根據套件公開資料產生的選型評估，僅供參考。
fake_async 是一個專為異步程式碼確定性測試設計的 Dart 套件。它允許開發者在受控環境中模擬計時器、微任務及其他非同步事件，確保測試結果具備可預測性和重複性。透過偽造非同步行為，它消除了對真實時間延遲的依賴，讓測試更快速且更可靠。非常適合包含非同步操作（例如 futures、streams 或排程任務）的單元測試與整合測試。

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.
| Package | Description | Issues | Version |

| checks | A framework for checking values against expectations and building custom expectations. |  |
 |
| fake_async | Fake asynchronous events such as timers and microtasks for deterministic testing. | |
