hitTest method
Tests whether the given point, on a rectangle of a given size, would be considered to hit the decoration or not. For example, if the decoration only draws a circle, this function might return true if the point was inside the circle and false otherwise.
The decoration may be sensitive to the TextDirection. The
textDirection
argument should therefore be provided. If it is known that
the decoration is not affected by the text direction, then the argument
may be omitted or set to null.
When a Decoration is painted in a Container or DecoratedBox (which
is what Container uses), the textDirection
parameter will be populated
based on the ambient Directionality (by way of the RenderDecoratedBox
renderer).
Implementation
@override
bool hitTest(Size size, Offset position, {TextDirection? textDirection}) {
return shape!
.getOuterPath(Offset.zero & size, textDirection: textDirection)
.contains(position);
}
