PathMetric class

Utilities for measuring a Path and extracting subpaths.

Iterate over the object returned by Path.computeMetrics to obtain PathMetric objects.

Once created, the methods on this class will only be valid while the iterator is at the contour for which they were created. It will also only be valid for the path as it was specifed when Path.computeMetrics was called. If additional contours are added or any contours are updated, the metrics need to be recomputed.


contourIndex int
The zero-based index of the contour. [...]
isClosed bool
Whether the contour is closed. [...]
length double
Return the total length of the current contour.
hashCode int
The hash code for this object. [...]
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited


extractPath(double start, double end, { bool startWithMoveTo: true }) Path
Given a start and stop distance, return the intervening segment(s). [...]
getTangentForOffset(double distance) Tangent
Computes the position of hte current contour at the given offset, and the angle of the path at that point. [...]
toString() String
Returns a string representation of this object.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]


operator ==(dynamic other) bool
The equality operator. [...]
