1、
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/l/master/example/android/app/src/main/AndroidManifest.xml uses `android:name="io.flutter.app.FlutterApplication"`
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Build failed due to use of deprecated Android v1 embedding.
处理方法
根据路径提示找到/Users/l/master/example/android/app/src/main/AndroidManifest.xml 下的 “android:name="io.flutter.app.FlutterApplication"”然后删除即可

3、
Cannot resolve symbol 'Properties'
Cannot resolve symbol 'GradleException'
处理方法，把new关键字删除
def localProperties = Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

此错误不影响运行。亦可忽略
