推荐答案

dispose 方法用于在删除状态对象时释放分配给变量的内存.

dispose method use to release the memory allocated to variables when state object is removed.

例如，如果您在应用程序中使用流，则必须释放分配给streamController的内存.否则，您的应用可能会从playstore和appstore收到有关内存泄漏的警告.

For example, if you are using a stream in your application then you have to release memory allocated to streamController. Otherwise your app may get warning from playstore and appstore about memory leakage.
