LegendContainer class

Lays out the legend area for the chart.

The legend area contains individual legend items. Each legend item has a color square and text, which describes one data row (that is, one data series).

Currently, each individual legend item is given the same size, so legends texts should be short.

This ChartAreaContainer operates as follows:

  • Horizontally available space is all used (filled).
  • Vertically available space is used only as much as needed. The used amount is given by the maximum label or series indicator height, plus extra spacing.

Constructors

LegendContainer({required ChartTopContainer chartTopContainer})
Constructs the container that holds the data series legends labels and color indicators.

Properties

chartTopContainer → ChartTopContainer
The chart top level.
finalinherited
enableSkipOnDistressedSize ↔ bool
If size constraints imposed by parent are too tight, some internal calculations of sizes may lead to negative values, making painting of this container not possible.
getter/setter pairinherited
hashCode → int
The hash code for this object.
no setterinherited
isDistressed ↔ bool
getter/setter pairinherited
layoutSize ↔ Size
Manages the layout size during the layout process in layout. Should be only mentioned in this class, not super
getter/setter pairinherited
offset ↔ Offset
Current absolute offset, set by parent (and it's parent etc, to root).
getter/setter pairinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
skipByParent ↔ bool
skipByParent instructs the parent container that this container should not be painted or layed out - as if it collapsed to zero size.
getter/setter pairinherited
tiltMatrix → Matrix2
Provides access to tiltMatrix for extension's paint methods.
no setterinherited

Methods

applyParentOffset(Offset offset) → void
Allow a parent container to move this Container after layout.
applyParentTiltMatrix(Matrix2 tiltMatrix) → void
Tilt may apply to the whole container. todo-2 unused? move to base class? similar to offset?
inherited
layout(LayoutExpansion parentLayoutExpansion) → void
Lays out the legend area.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas) → void
toString() → String
