A simple package for adding a Diamond Floating Action Button or FAB to a flutter application. This FAB also allows for a notch to be made inside of the Bottom Application Bar or Bottom Navigation Bar based on the positioning.

FAB code is based on the original Floating Action Button Source code and the Material Design specification.

Getting Started

Add this to your package's pubspec.yaml file:

  diamond_fab: "^0.1.0"


Center docked with wider margin Center Float with normal margin End docked with narrow margin

[0.0.1] - First Release.

[0.1.0] - Updated properties and button drawing method

Added new properties for foreground color, background color, heroTag, highlightElevation, mini (miniMode), and tooltip. Added more documentation (again based on the original Floating Action Button code).

[0.1.1] - Changed normal size based on Material design Spec

Diamond Shaped FAB is 68 logical pixels in size on the material design spec compared to the normal 56.0 logical pixels. Also changed mini size to 52 rather then 40.
