Closed deboLing closed 3 years ago

deboLing commented 3 years ago

在iOS上，打开网页关闭后，其他页面会卡顿。

日志如下：

Can you give me the code to reproduce this problem?

Can you give me the code to reproduce this problem?

WebView( initialData: WebViewData(Platform.isIOS ? "$userRule" : "$userRule"), )

deboLing commented 3 years ago

开发测试环境会卡顿、上架后不会卡顿

hisaichi5518 commented 3 years ago

@deboLing Can you provide actual working code? Also, what kind of value does the userRule contain?

hisaichi5518 commented 3 years ago

This issue can be resolved by using Flutter 1.24.0-6.0.pre. Thanks!
