发行模式下的Flutter AWS Cognito应用在Android上崩溃

如何解决发行模式下的Flutter AWS Cognito应用在Android上崩溃

我创建了一个Flutter应用程序，该应用程序使用amplify_auth_cognito和amplify_core软件包进行身份验证。

在调试模式下，该应用程序运行正常，没有任何问题。即使从TestFlight安装，iOS版本也可以正常工作。

但是，当我在发布模式下运行时，在物理Android设备上创建了apk，每当我单击调用Amplify.Auth.signIn(username,password)函数的按钮时，整个应用就会崩溃。

应用崩溃日志说：
