我的flutter应用程序可以在调试模式下正常工作，但是当我尝试以发布模式运行它时，出现了gradle task assemblerelease failed with exit code 1错误
flutter run --release
同样的问题
我删除了.gradle文件，同样的问题仍然出现
我从
classpath 'com.android.tools.build:gradle:3.4.2'
至
classpath 'com.android.tools.build:gradle:3.5.0'
不起作用
我不知道该怎么办
flutter run --release -v日志是Gradle task assembleRelease failed with exit code 1
