BubbleSeries<T, D> class Null safety

This class holds the properties of the bubble series.

To render a bubble chart, create an instance of BubbleSeries, and add it to the series collection property of SfCartesianChart. A bubble chart requires three fields (X, Y, and Size) to plot a point. Here, sizeValueMapper is used to map the size of each bubble segment from the data source.

Provide the options for color, opacity, border color, and border width to customize the appearance.
