Using Floating action button with PageView

I'm trying to use Flutter FAB in PageView, but since the FAB takes a variable that is initialized in the page 2, it creates an error.

So how can i show the FAB only after the second page?

Solution

  • The solution I used was to set a callback with the bool floating.

    on the home page:

    `

    bool floating = false;
showFAB(show) {
    setState(() {
      floating = show;
    });
  }`

    floatingActionButton:(floating) ? FloatingMenu(pageController: pageController) : null,

    then on the initState function of second page used the callback to change the bool value
