BasePointer class abstract

A BasePointer is a widget that is used to indicate the value of the LinearGauge.

The LinearGauge takes a list of BasePointer as an input i.e Pointer & WidgetPointer. value Sets the value of the pointer height and weight Sets the height & weight of the pointer child adds the custom widget as a pointer PointerShape Sets the shape of the pointer

Note: The value of the pointer should be between the start and end value of the LinearGauge and if the value is null it takes the value specified in Linear Gauge

const LinearGauge(
   pointers: const [
     Pointer(
      value: 50.0,
      color: Colors.red,
      shape: PointerShape.circle,
   ),
     WidgetPointer(
      value: 20.0,
      child: Image.assets("image",height:100,width:100),
   ),
  ],
),
