DiamondFab class

A material design diamond shaped floating action button.

Unlike the basic floating action button, this button is diamond shaped by default. It is commonly used in the Scaffold.floatingActionButton field.

Use a single floating action button per screen. Floating action buttons are used for primary and positive actions.

if onPressed is null, then button will be disabled and will not react to touch.

As with the normal FloatingActionButton the DiamondFab also will include a notch inn the BottomAppBar if there is one and the FloatingActionButtonLocation is docked. In this case, the edges of the notch are a triangle or Rhombus rather then a circle. See also:
