推荐答案
感谢您的建议，
我已通过以下步骤解决了该问题：
1.尝试添加此行在您的Project文件夹> android> app> build.gradle中，添加以下行
I've fixed it by doing these steps : 1. Try adding this line In your Project folder > android > app > build.gradle, add the following Line in
multiDexEnabled true
内部defaultConfig
inside defaultConfig

然后在android / build.gradle文件中升级gradle依赖项：c lasspath'com.android.tools.build:gradle:3.3.1'（先前在3.2.1版上）
Then upgrade gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (previously on version 3.2.1)
运行flutter clean并重建项目
Run flutter clean and rebuild your project
