Flutter Speed Dial

Flutter package to render a Material Design Speed Dial.

Flutter Speed Dial

Usage

The SpeedDial widget is built to be placed in the Scaffold.floatingActionButton argument, replacing the FloatingActionButton widget. It's not possible to set its position with the Scaffold.floatingActionButtonLocation argument, but it's possible to set right/bottom margin with the marginRight and marginBottom arguments (default to 16) to place the button anywhere in the screen. Using the Scaffold.bottomNavigationBar the floating button will be always placed above the bar, so the BottomAppBar.hasNotch should be always false.

Labels

Every child button can have a label, which can be customized providing a labelStyle. If the label parameter is not provided the label will be not rendered.

Animated Icon

The main floating action button child can set with the child parameter, however to make easier to use an AnimatedIcon there are two specific parameters:

  • animatedIcon takes an AnimatedIconData widget
  • animatedIconTheme takes its theme

The package will handle the animation by itself.

Hide on Scroll

Another possibility is to make the button hide on scroll with a curve animation, with a visible parameter to set dynamically based on the scroll direction. See the example project for more info.

Example Usage:

Widget build(BuildContext context) {
    return Scaffold(
        floatingActionButton: SpeedDial(
          // both default to 16
          marginRight: 18,
          marginBottom: 20,
          animatedIcon: AnimatedIcons.menu_close,
          animatedIconTheme: IconThemeData(size: 22.0),
          // this is ignored if animatedIcon is non null
          // child: Icon(Icons.add),
          visible: _dialVisible,
          curve: Curves.bounceIn,
