Properties

activeSymbol → String: Current active symbol.
final
annotations → List<ChartAnnotation<ChartObject>>?: Chart's annotations
final
bottomChartTitleMargin → EdgeInsets?: Specifies the margin to prevent overlap.
final
chartAxisConfig → ChartAxisConfig: Configurations for chart's axes.
final
controller → ChartController?: Chart's controller
final
crosshairVariant → CrosshairVariant: The variant of the crosshair to be used. This is used to determine the type of crosshair to display. The default is CrosshairVariant.smallScreen. CrosshairVariant.largeScreen is mostly for web.
final
currentTickAnimationDuration → Duration?: Duration of the current tick animated transition.
final
dataFitEnabled → bool: Starts in data fit mode and adds a data-fit button.
final
dataFitPadding → EdgeInsets?: Padding around data used in data-fit mode.
final
drawingTools → DrawingTools?: Drawing tools
final
drawingToolsRepo → Repository<DrawingToolConfig>?: Chart's drawings
final
granularity → int: For candles: Duration of one candle in ms. For ticks: Average ms difference between two consecutive ticks.
final
hashCode → int: The hash code for this object.
no setterinherited
indicatorsRepo → Repository<IndicatorConfig>?: Chart's indicators
final
interactiveLayerBehaviour → InteractiveLayerBehaviour?: Defines the behaviour that interactive layer should have.
final
isLive → bool: Whether the chart should be showing live data or not. In case of being true the chart will keep auto-scrolling when its visible area is on the newest ticks/candles.
final
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
loadingAnimationColor → Color?: The color of the loading animation.
final
magnetEnabled → bool: Whether new drawing tool points snap to the nearest candle's time bucket instead of the exact cursor position ("magnet" mode).
final
mainSeries → DataSeries<Tick>: Chart's main data series
final
markerSeries → MarkerSeries?: Open position marker series.
final
maxIntervalWidth → double?: Specifies the maximum interval width that is used for calculating the maximum msPerPx.
final
minIntervalWidth → double?: Specifies the minimum interval width that is used for calculating the maximum msPerPx.
final
msPerPx → double?: Specifies the zoom level of the chart.
final
onCrosshairAppeared → VoidCallback?: Called when crosshair details appear after long press.
final
onCrosshairDisappeared → VoidCallback?: Called when the crosshair is dismissed.
final
onCrosshairHover → OnCrosshairHoverCallback?: Called when the crosshair cursor is hovered/moved.
final
onQuoteAreaChanged → VisibleQuoteAreaChangedCallback?: Callback provided by library user.
final
onVisibleAreaChanged → VisibleAreaChangedCallback?: Called when chart is scrolled or zoomed.
final
opacity → double: Chart's opacity, Will be applied on the mainSeries.
final
pipSize → int: Number of digits after decimal point in price.
final
quoteBoundsAnimationDuration → Duration?: Duration of quote bounds animated transition.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
showCrosshair → bool: Whether the crosshair should be shown or not.
final
showCurrentTickBlinkAnimation → bool?: Whether to show current tick blink animation or not.
final
showDataFitButton → bool?: Whether the data fit button is shown or not.
final
showScrollToLastTickButton → bool?: Whether to show the scroll to last tick button or not.
final
theme → ChartTheme?: Chart's theme.
final
useDrawingToolsV2 → bool: Whether to use the new drawing tools v2 or not.
final
verticalPaddingFraction → double?: Fraction of the chart's height taken by top or bottom padding. Quote scaling (drag on quote area) is controlled by this variable.
final
