when card A quickly switches to card B, there is a significant delay in closing card A,

[ddxl123]

I attempted to implement a global InAppWebView and used keepAlive. However, when rapidly switching between multiple pages (such as in the carousel_slider package), when card A quickly switches to card B, there is a significant delay in closing card A, resulting in the dispose method of card A not being called until after switching to card B, causing card B to display nothing.
