我目前在Flutter的主频道2.6.0-12.0.pre.406版本，每次我运行一个应用程序，我都会在控制台上收到这些奇怪的消息，我只是想知道为什么，它们意味着什么，如果我可以忽略这些消息。甚至当我新创建一个应用程序，运行它没有编辑任何东西时也会发生这种情况。所以即使当我运行示例应用程序时。
输出如下：

Running Gradle task 'assembleDebug'...                              7,0s

我有同样的错误，一旦我集成Firebase到我的Flutter应用程序。这可能不是一个合法的解决方案，这个错误，但这里是我所做的。
1.升级minSdkVersion到24（ANDROID/应用程序/版本.gradle）
通常firebase要求我们将SDK升级到19。出于测试目的，我将其更改为更高的SDK（在本例中为24）。
1.清洁和构建Gradle
然后我用以下命令清理了我们的android gradle文件;

cd android-〉如果你是在你的Flutter项目的根源
./gradlew clean-〉清理Gradle环境
./gradlew build-〉在干净的环境中重建

1.在Flutter环境中清洁和运行

返回到根
flutter clean-〉清除Flutter工作区
flutter pub get-〉取回已删除的包和依赖项
flutter run-〉运行应用程序

我希望这能帮助到一些人，正如我所说的，这不是一个合法的解决方案，但它对我来说是有效的。如果这失败了。还可以考虑通过以下方式检查JAVA和Gradle SDK版本的兼容性：

cd android-〉回到Android项目。
java --version-〉检查Java版本。
./gradlew --version-〉检查gradle版本。使用上面的命令，您可以在此处检查兼容性

将这些行添加到AndroidManifest.xml文件为我解决了这个问题：

<meta-data
android:name="io.flutter.embedding.android.SplashScreenDrawable"
android:resource="@drawable/launch_background" />

但运行控制台上出现警告：

W/FlutterActivityAndFragmentDelegate(21657): A splash screen was provided to Flutter, but this is deprecated. See flutter.dev/go/android-splash-migration for migration steps.

我已经解决了这个问题。如果你正在使用flutter_splash_screen包，你应该删除这个包并更新AndroidManifest.xml和styles.xml。
