關於 flutter GridView ListView 加載多張大圖oom，Message from debugger: Terminated due to memory issue

看起來像是flutter本身的內存管理釋放問題，即使在頁面釋放image的cache也不行。

原因是因為舊版本的flutter對GridView和ListView組件加載高分辨率圖片的緩存和回收處理有問題導致內存暴漲無法自動回收，手動關掉緩存，清圖片cache也不行。官方在最新master分支代碼解決了這個問題，加載圖片的時候內存占用沒有明顯波動

而且問了下不會merge到1.9.1hotfixes分支。只能等最新的穩定版了，或者自己改一個版本
