问题：
Warning ────────────────────────────────────────────────────────────────────────────── Your Flutter application is created using an older version of the Android embedding. It is being deprecated in favor of Android embedding v2. Follow the steps at https://flutter.dev/go/android-project-migration to migrate your project. You may also pass the --ignore-deprecation flag to ignore this check and continue with the deprecated v1 embedding. However, the v1 Android embedding will be removed in future versions of Flutter. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ The detected reason was: /Users/mm/Desktop/studyProject/adDemo/android/app/src/main/AndroidManifest.xml uses `android:name="io.flutter.app.FutterApplication"` ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Build failed due to use of deprecated Android v1 embedding.
解决：
android/app/src/main下的找到AndroidManifest.xml修改application标签内容如下：
android:name="${applicationName}" //修改之前的android:name="io.flutter.app.FlutterApplication"
