Google PlayStore中我的应用程序捆绑包下载大小约为23 MB：
但是，为什么安装后，磁盘上的应用程序大小显着增加到83 MB：
任何想法为什么会这样，因为：
1）Flutter的资产文件（图像，声音和字体）仅在11 MB左右的项目上
2）磁盘上Flutter源代码（.dart）的大小仅为1.4 MB
3）Android Native Resource / icon（Res）仅约800 KB

更新
如果我在中设置minifyEnabled = true和shrinkResources = true（如Ravinder Kumar的建议），build.gradle它将产生一个很长的错误，这是日志：
