WidgetItemOptions class

Options for widget items.

widgetItemBuilder returns a Widget that will be shown as ChartItem.

multiStackItem This has effect only if you have multiple lists. Should the items stack one on top of the other. If false items will be shown side by side in single itemWidth

To show basic chart you can just use:

itemOptions: WidgetItemOptions(
  chartItemBuilder: (data) => Container(color: Colors.red),
),

You can replace your ValueDecoration with WidgetItemOptions like this:

itemOptions: WidgetItemOptions(
 chartItemBuilder: (data) => Container(
  color: Colors.red,
  child: Center(
    child: Text(
      '${item.max?.toString()}',
      style: TextStyle(color: Colors.white),
    ),
  ),
 ),
),

Other options are reverted to 0 since you can set everything in the builder.
