Build 颤振应用程序Android studio 3.2.1，构建失败

我将Android studio更新为3.2.1，并在Mac终端上运行“颤振构建apk”，它显示以下错误。在更新Android studio之前，我成功地构建了apk

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> Job failed, see logs for details

这是我的proguard-rules.pro

#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.**  { *; }
-keep class com.google.firebase.** { *; }

转到android/app/build.gradle并尝试

minifyEnabled false

它应该可以工作

这解决了我的问题

 #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.**  { *; }
-dontwarn android.**
