The SpeedDial widget is built to be placed in the Scaffold.floatingActionButton argument, replacing the FloatingActionButton widget. You can set its position using Scaffold.floatingActionButtonLocation argument. It can also be used with Scaffold.bottomNavigationBar and Snackbar.

Null safety is available from version 3.0.5 ( It is also backward compatible, meaning you can use it with non null safe code too )

Labels

SpeedDial can take any Widget as label SpeedDial will use Extended FloatingActionButton property if label is specified. It also have activeLabel property by which you can specify the label which is shown when SpeedDial is open. It also comes with its labelTransitionBuilder which defaults to fade transition.

Also Every child's button have label property which accepts String which can be styled by using labelStyle. If you want to specify a widget then you can use labelWidget.
If the label parameter is not provided, then the label will be not rendered.

Close on WillPop

Although it doesn't magically closes when you press back button, but requires a easier setup to enable this functionality, here are the steps that you need to do to enable that:

  1. Add a value Notifier inside your widgets build context where your SpeedDial is placed like below.
ValueNotifier<bool> isDialOpen = ValueNotifier(false);
  1. Then you need to add a property to your SpeedDial known as openCloseDial like below.
  openCloseDial: isDialOpen,
  1. Add a will Pop in your body or anywhere where you want and then simply add the following line in its onWillPop element.
WillPopScope(
  onWillPop: () async {
    if (isDialOpen.value) {
      isDialOpen.value = false;
      return false;
    }
    ...other checks here
  }
  child: ...your child goes here
)
