overlayOpeningAnimationDurationMs

The duration (in milliseconds as a positive long) of the opening animations for ALL the Overlays inside of this ExpandableFabLayout. A convenience method so that clients don't have to set the same value for every Overlay within a single ExpandableFabLayout.

Set to 0L if you don't want opening animations for ANY Overlays within this ExpandableFabLayout.

NOTE: This property will override whatever you set on individual Overlays. If you only want to change the opening animation duration for a single Overlay, leave this property as null. See Overlay.openingAnimationDurationMs.
