ChartMarker typedef
ChartMarker = ({bool above, Color? color, bool filled, Color? haloColor, double? haloRadius, String? label, Color? outlineColor, double? outlineWidth, double? radius, double x, double y})
A circle on a point with an optional label above or below it. A marker may style itself (a result-coloured dot on a halo, say); unset styles fall back to the chart's: radius 5, filled with the line colour or the hollow colour, a 2px outline in the line colour.
