flutter集成JPush，使用混淆打包出现错误。(集成JPush之前已集成了JMessage，混淆打包成功。)

• 混淆配置：

#Flutter Wrapper
-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.**  { *; }
-keep class io.flutter.util.**  { *; }
-keep class io.flutter.view.**  { *; }
-keep class io.flutter.**  { *; }
-keep class io.flutter.plugins.**  { *; }

# 极光
-dontoptimize
-dontpreverify
-keepattributes  EnclosingMethod,Signature
-dontwarn cn.jpush.**
-keep class cn.jpush.** { *; }
-keep class * extends cn.jpush.android.helpers.JPushMessageReceiver { *; }

-dontwarn cn.jiguang.**
-keep class cn.jiguang.** { *; }

-dontwarn cn.jmessage.**
-keep class cn.jmessage.**{ *; }

-keepclassmembers class ** {
    public void onEvent*(**);
}
