WheelOverlayEntryContent class Null safety

WheelOverlayEntryContent is the content of the Overlay that we want to show. With this setup, on can use WheelOverlayEntryContent separately from the main WheelColorPicker widget.

Also it saves some computation such that it only has to be built once when parent widget is initializing, after the first time, parent widget just has to pump new OverlayEntry with this as the content

final, inherited
layerLinkConfig LayerLinkConfig
see LayerLinkConfig WheelOverLayEntryContent uses layerLinkConfig to decide whether to link this overlay to a target. This link is necessary for metric changes or scroll when you want the layer to stick to some element(target).
final
onSelect → void Function(Color)
invoked when user clicks on a FanPieceWidget
final
padding double
padding between outer radius and the outer container
final
pieceBorderSize double
