Question

我已经安装了Flutter，并且没有任何问题，我可以编写代码并构建调试apk和热重载，但是无法构建应用程序的发行版。

将flutter beta频道从v0.10.2升级到v0.11.3之后，我遇到了同样的问题。我花了几个小时找出这个问题。希望这也对您有用：

方法1：

将文件夹android重命名为android.save
创建另一个名为dummy的Flutter项目
从虚拟项目中复制android文件夹
将android\app文件夹替换为先前保存的文件夹（android.save\app）
运行一个干净的版本： flutter clean;flutter build apk --release --verbose

方法2：

切换到另一个颤动通道，然后再切换回也可以解决此问题。它在另一台机器上对我有用。
