Flutter Speed Dial #

Flutter package to render a Material Design Speed Dial.

Usage #

The SpeedDial widget is built to be placed in the Scaffold.floatingActionButton parameter. It's not possible to set its position with the Scaffold.floatingActionButtonLocation parameter though. The use with the Scaffold.bottomNavigationBar is possible but the floating button will be placed above the bar, so the BottomAppBar.hasNotch should be 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.
