Top edge treatment for the bottom app bar which "cradles" a circular FloatingActionButton.
This edge features a downward semi-circular cutout from the edge line. The two corners created by the cutout can optionally be rounded. The circular cutout can also support a vertically offset FloatingActionButton; i.e., the cut-out need not be a perfect semi-circle, but could be an arc of less than 180 degrees that does not start or finish with a vertical path. This vertical offset must be positive.

BottomAppBarTopEdgeTreatment
BottomAppBarTopEdgeTreatment (float fabMargin,
float roundedCornerRadius,
float cradleVerticalOffset)
| Parameters | |
|---|---|
fabMargin |
float: the margin in pixels between the cutout and the fab. |
roundedCornerRadius |
float: the radius, in pixels, of the rounded corners created by the cutout.
A value of 0 will produce a sharp cutout. |
cradleVerticalOffset |
float: vertical offset, in pixels, of the FloatingActionButton
being cradled. An offset of 0 indicates the vertical center of the FloatingActionButton is positioned on the top edge.

Public methods
getEdgePath
void getEdgePath (float length,
float interpolation,
ShapePath shapePath)
Generates a ShapePath for this edge treatment.
EdgeTreatments have an origin of (0, 0) and a destination of (0, length) (i.e. they represent the top edge), and are be automatically rotated and scaled as necessary when applied to other edges. Only the horizontal, top EdgeTreatment needs to be defined in order to apply it to all four edges.
| Parameters | |
|---|---|
length |
float: the length of the edge. |
interpolation |
float: the interpolation of the edge treatment. Ranges between 0 (none) and 1
(fully) interpolated. Custom edge treatments can implement interpolation to support shape
transition between two arbitrary states. Typically, a value of 0 indicates that the custom
edge treatment is not rendered (i.e. that it is a straight line), and a value of 1
indicates that the treatment is fully rendered. Animation between these two values can
"heal" or "reveal" an edge treatment. |
shapePath |
ShapePath: the ShapePath that this treatment should write to.
