Hi @duytient31!

Sorry, I do not understand. I don't know if you're talking about the hidden tabs. If so, this is dynamic and only occurs when there is no space for them to be displayed on the screen.

I have similar question, when you switch tabs, the tab's widget's states are recreated, causing the page rerendered, how to keep the state?

Hi @zzt741 !

Sure! It's the keepAlive (I thought it best to keep the same name used by Flutter)

https://github.com/caduandrade/tabbed_view#keep-alive

    List<TabData> tabs = [];
    tabs.add(TabData(
        text: 'Tab',
        content: Padding(child: Text('Hello'), padding: EdgeInsets.all(8))));
    tabs.add(TabData(
        text: 'TextField',
        content: Padding(
            child: TextField(
                decoration: InputDecoration(
                    isDense: true, border: OutlineInputBorder())),
            padding: EdgeInsets.all(8)),
        keepAlive: true));

    TabbedViewController controller = TabbedViewController(tabs);
    TabbedView tabbedView = TabbedView(controller: controller);

@duytient31 , I'm considering that your question is the same ok?
