我正在尝试为我的应用程序设置 Flutter Driver 测试，并且应用程序运行异步，所以我发现https://github.com/flutter/flutter/issues/41029它说你需要做的就是添加await driver.waitUntilFirstFrameRasterized();并且它应该可以工作，而这确实阻止了测试失败，它根本不会运行。

该应用程序只是挂在启动屏幕上，甚至从未进入应用程序本身。

据我了解，这就是我需要进行的所有设置才能运行测试

  FlutterDriver driver;
  // Connect to the Flutter driver before running any tests.
  setUpAll(() async {
    driver = await FlutterDriver.connect();
    await driver.waitUntilFirstFrameRasterized();

    // await Directory('screenshots').create();
  });

  // Close the connection to the driver after the tests have completed.
  tearDownAll(() async {
    if (driver != null) {
      await driver.close();
    }
  });

但是，我在终端中得到的只是以下输出：

VMServiceFlutterDriver: Connecting to Flutter application at http://127.0.0.1:54264/tt9kN4jBSrc=/
VMServiceFlutterDriver: Isolate found with number: 2942164624858163
VMServiceFlutterDriver: Isolate is paused at start.
VMServiceFlutterDriver: Attempting to resume isolate
VMServiceFlutterDriver: Connected to Flutter application.
VMServiceFlutterDriver: waitForCondition message is taking a long time to complete...

我已经离开了几分钟，但什么也没发生，我已经禁用了 firebase 初始化，以防万一它被阻止，因为我需要接受警报对话，而不是我什至可以看到那么远。

原来我也需要IsolatesWorkaround使用

  FlutterDriver driver;
  IsolatesWorkaround workaround;
  // Connect to the Flutter driver before running any tests.
  setUpAll(() async {
    driver = await FlutterDriver.connect();
    workaround = IsolatesWorkaround(driver);
    await workaround.resumeIsolates();
    await driver.waitUntilFirstFrameRasterized();

    if (!await Directory('screenshots').exists()) {
      await Directory('screenshots').create();
    }
  });

  // Close the connection to the driver after the tests have completed.
  tearDownAll(() async {
    await driver?.close();
    await workaround.tearDown();
  });
