smooth_line_chart 0.0.6

The simplest way to add stunning line charts to your Flutter app. Smooth bezier curves, tap/hover tooltips, dark mode, gradient fill, async data loading — all with zero dependencies.

0.0.5

• padding — inner padding around the chart area (default EdgeInsets.zero).
• Fix value labels overlapping Y-axis at leftmost point (clamp X position).
• Fix value labels hidden when data point is near top of chart (flip below point).
• Removed stale lib/main.dart from package root.

0.0.4

Functional

• onPointTap — callback when user taps a data point (index, x, y, qty, range).

• yMin — set a minimum Y value so charts with high baseline data aren't flat.

• emptyWidget — custom widget shown when yValues is empty; defaults to "No data".

• onRangeChanged on SmoothLineChartAsync — called whenever the user switches range.

• height — fixed chart height in pixels as alternative to aspectRatio.

Visual

• ChartTheme.showDots + dotRadius — show dots at every data point.
• ChartTheme.showValueLabels + valueLabelStyle — show Y value text above each point.
• ChartTheme.fillGradient — gradient fill below the line (overrides fillColor).
• backgroundColor + borderRadius on ChartCard / SmoothLineChart — card styling.

0.0.3

• Fix tooltip dismiss — tapping the active point now correctly hides the tooltip (was re-shown by onPanUpdate firing after onTapDown).
• Y labels overlay — new yLabelOverlay: true (default) draws Y labels inside the chart, making it flush with any title above it. No extra left space consumed.
• Tooltip arrow — new tooltipArrow: true shows a downward triangle pointer on the tooltip pointing toward the active data point.

0.0.2

• Flexible JSON parsing — ChartData.fromMap() and ChartData.fromList() factories for any JSON shape. fromPayload now also accepts flat lists and common key aliases (label, x, y, quantity, dateRange).
• Tooltip dismiss — tap the active point again (or anywhere outside the chart) to close the tooltip on mobile/touch devices.
• Grid toggle — ChartTheme.showGrid (default true); set to false to hide all grid lines.
• Custom Y-axis labels — ChartCard.yAxisLabels / SmoothLineChart.yAxisLabels lets you supply arbitrary text for each Y tick (e.g. ['0', '500 Rb', '1 Jt']).

0.0.1

• Initial release.
• ChartCard — interactive line + area chart with hover/tap tooltips.
• SmoothLineChart — simple one-widget entry point with optional title.
• SmoothLineChartAsync — built-in range selector + async data loading.
• RangeSelector — customizable pill-button time range picker.
• ChartData — data model with optional fromPayload factory.
• ChartTheme — full color/style configuration including a dark preset.
• Zero external dependencies — pure Flutter + dart:math.
