Implementation

Widget buildFluentChartPopoverMultiValue(
  FluentChartPopoverData data,
  FluentChartPopoverStyle style,
  Color fallbackForeground,
) {
  const states = <WidgetState>{};
  final values = data.yValues ?? const <FluentYValueHover>[];
  final hasSubCounts = fluentChartPopoverHasSubCounts(values);

  final rows = <Widget>[
    for (var index = 0; index < values.length; index++)
      _popoverRow(
        values[index],
        style,
        fallbackForeground,

        hasSubCounts: hasSubCounts,
        // ChartPopover.tsx:187 — every column but the last carries a 16px
        // trailing margin.
        isLast: index == values.length - 1,
      ),
  ];

  return Column(
    crossAxisAlignment: CrossAxisAlignment.start,
    mainAxisSize: MainAxisSize.min,
    children: <Widget>[
      Padding(
        // ChartPopover.tsx:122 — 11px below the date container, but only when
        // subcounts exist. The same 11 as the single-value accent bar margin.
        padding: EdgeInsets.only(
          bottom: hasSubCounts ? kChartPopoverAccentBarMarginTop : 0,
        ),

          style: style.xTextStyle!.resolve(states),
        ),
