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.

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"
