如何在 flutter 中长按列表视图显示浮动操作按钮

Question

I am creating an app that should contain a list on long pressing a list item the floating action button should be displayed on bottom of screen

Answer 1

Wrap you list item with GestureDetector it has a property called onLongPress .You can keep a bool value set to false and onLongPress set the bool to true and show the floating action button.

#Edit1 declare a bool,

bool showFab = false;

your FAB

floatingActionButton: showFab ? FloatingActionButton(...) : SizedBox(),

Your listtile

GestureDetector(
    onLongPress: () {
      setState((){
showFab = true;
})
    },
    child: YourListWidget(),
  )
