Methods

aroundCircle({Point<double>? at, required double radius, required int n, required dynamic callback(Point<double>, int)}) → void: Defaults to rotating around center of Canvas
background(double h, double s, double l, [double a = 100]) → void: Fill the background. Color is hsl(a), h goes from 0 to 360, others from 0 to 100.
clipped() → dynamic: Clip your drawing to the Canvas size
doProportion(double proportion, dynamic callback()) → void: Do the callback a proportion of times
draw(SPath path) → void: Draw a Solandra SPath (shape/path) with the current strokePaint
drawPath(Path path) → void: Draw (stroke) a conventional Dart Path with the current strokePaint
fill(SPath path) → void: Fill a Solandra SPath (shape/path) with the current fillPaint
fillPath(Path path) → void: Fill a conventional Dart Path with the current fillPaint
forFrame({required dynamic callback(Area area), double? margin}) → void: Get a drawable Area for painting after adding a margin (proportionate)
forGrid({int minX = 0, required int maxX, int minY = 0, required int maxY, bool columnFirst = true, required dynamic callback(Point<int> point, int index)}) → void: Iteration over an integer grid
forHorizontal({required int n, double margin = 0.0, required dynamic callback(Area area)}) → void: Go across canvas in chunks, with optional margin
forTiling({required int n, bool square = true, double margin = 0, bool columnFirst = true, required dynamic callback(Area area)}) → void: Helper for tiling a canvas
forVertical({required int n, double margin = 0.0, required dynamic callback(Area area)}) → void: Go down canvas in chunks, with optional margin
gaussian({double mean = 0, double sd = 1}) → double: Get a random Gaussian value
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
perturb({required Point<double> at, required double magnitude}) → Point<double>: Perturb a point (by uniform amount in 2D)
poisson(int lambda) → int: Get a random Poisson value
proportionately(List<Case> cases) → void: Give a bunch of cases, do one with probability in proportion to proportion given.
random() → double: Get a random number
randomAngle() → double: Get a random angle
randomBool() → bool: Get a random boolean
randomInt(int max) → int: Get a random integer
randomPoint() → Point<double>: Get a random point on the canvas
sample<T>(List<T> items) → T: Pick an item from a list at random
samples<T>(List<T> items, int count) → List<T>: Pick many items from a list at random (with replacement)
setFillColor(double h, double s, double l, [double a = 100]) → void: Set the color for fillPaint. Color is hsl(a), h goes from 0 to 360, others from 0 to 100.
setStrokeColor(double h, double s, double l, [double a = 1.0]) → void: Set the color for strokePaint. Color is hsl(a), h goes from 0 to 360, others from 0 to 100.
shuffle<T>(List<T> items) → List<T>: Shuffle a List, importantly uses same RNG as other random code.
toString() → String: A string representation of this object.
