PrismLineChart class

A token-styled line chart with optional gradient fill and points.

Pure CustomPainter — no fl_chart dependency. Provide labels to show an x-axis; they are thinned automatically so they never overlap.

PrismLineChart(
  values: weeklyRevenue,
  labels: const ['Mon', 'Tue', 'Wed', 'Thu', 'Fri'],
  semantic: PrismSemantic.success,
)

PrismLineChart({Key? key, required List<double> values, List<String> labels = const [], double height = 180, Color? color, PrismSemantic? semantic, bool fill = true, bool showPoints = true, bool showGrid = true}): Creates a line chart. Requires at least two values.
const

color → Color?: Stroke colour; defaults to the role colour from semantic, then primary.
final
fill → bool: Whether to fill the area under the line.
final
hashCode → int: The hash code for this object.
no setterinherited
height → double: Chart height, excluding the label strip.
final
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
labels → List<String>: Optional x-axis labels, one per value; thinned to fit.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
semantic → PrismSemantic?: Semantic role picking the stroke colour when color is null.
final
showGrid → bool: Whether to draw horizontal gridlines.
final
showPoints → bool: Whether to draw a dot per point.
final
values → List<double>: The series, in x order.
final

build(BuildContext context) → Widget: Describes the part of the user interface represented by this widget.
override
createElement() → StatelessElement: Creates a StatelessElement to manage this widget's location in the tree.
inherited
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode: Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String: A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A short, textual description of this widget.
