Methods

animateTo(DecorationPainter endValue, double t) → DecorationPainter

Animate to next decoration state, each decoration should implement this. This is just regular lerp function, but instead of static function where you pass start and end state, here we start with current state and animate to endValue.

override

applyPaintTransform(ChartState state, Size size) → Offset

override

draw(Canvas canvas, Size size, ChartState state) → void

Draw decoration. Decoration can be foreground or background decoration that will be drawn on the chart decorations can ignore padding and can use whole available canvas to draw.

override

getRenderer(ChartState state) → Widget

inherited

initDecoration(ChartState state) → void

Init decoration is first thing called on decorations, it will pass current ChartState so decoration can easily calculate needed stuff for their layout.

inherited

isSameType(DecorationPainter other) → bool

Used for animating, we just need to find matching type, don't actually check for equality since we want to animate from one state to other. Some decorations may consider overriding this in case multiples are used

inherited

layoutSize(BoxConstraints constraints, ChartState state) → Size

override

marginNeeded() → EdgeInsets

Get extra margin (not definable by the user). This makes sure that any decoration that leaves original drawing window is not drawing outside of that window (This is not enforced right now but it's unwanted behaviour)

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

paddingNeeded() → EdgeInsets

Get extra padding (not definable by user, calculated by decoration if needed). This makes sure that decoration will fit with the chart in wanted area.

inherited

toString() → String

A string representation of this object.
