How can i toggle the sliver appbar to activate or deactivate itself and act as a normal appbar?

Question

我的应用程序中有2个选项卡，当我在第二个选项卡上但在第一个选项卡上保持灵活时，我是否可以切换条子appbar以像普通appbar一样工作？

Answer 1

Without the sample code not much help could be provided. At the very least a GitHub link to the repo.

However based on your question you could look into state management. whereby there is conditional rendering of widget. The page will render a normal app bar in one state and the other state render the flexible app bar.
