flutter_sleep_chart 0.2.0

A lightweight, dependency-free Apple Health-style sleep stage chart widget for Flutter.

0.2.0

• Added onSegmentTap — called with the segment under the pointer on every pointer-down.
• Added showTimeAxis/timeAxisHeight for hour-aligned clock labels below the chart.
• Added showRowGridLines/showTimeGridLines/gridLineColor for optional row-divider and hourly grid lines.
• Added HypnogramLegend, a standalone color-dot + label legend widget for a stageStyles map.
• Added interactionMode (HypnogramInteractionMode.scrub (default) or .tap) — .tap ignores pointer-move so the chart doesn't fight a scrollable/draggable parent.
• Added enableAnimation/animationDuration/animationCurve — bars now animate in on first render and whenever segments changes (on by default).
• Added emptyBuilder for a custom placeholder when segments is empty.

0.1.0

• Breaking: replaced the colors/stageOrder/labels maps with a single stageStyles: Map<SleepStageType, StageStyle> — color, label, and an optional per-stage rowHeight override, in one place. Row order now follows the map's iteration order.
• Added HypnogramTooltipConfig (tooltip: param) to customize the scrub tooltip: per-field text overrides (labelText/timeRangeText/ durationText), bubble styling (background, text styles, padding, border radius, shadow, color-dot toggle), or a full builder override.
• Added labelColumnWidth param (previously a hardcoded constant).
• Fixed the tooltip floating above the chart's own bounds — it now clamps to the chart area and flips below the anchor row when there's no room above.

0.0.1

• Initial release: HypnogramChart widget — per-stage rows with glassy halo bars, gradient stage-transition connectors, minimum-width clamping for short segments, and a scrub tooltip (hover/tap/drag) with a guide line and stage-colored dot.
