PathMetrics class Null safety

An iterable collection of PathMetric objects describing a Path.

A PathMetrics object is created by using the Path.computeMetrics method, and represents the path as it stood at the time of the call. Subsequent modifications of the path do not affect the PathMetrics object.

Each path metric corresponds to a segment, or contour, of a path.

For example, a path consisting of a Path.lineTo, a Path.moveTo, and another Path.lineTo will contain two contours and thus be represented by two PathMetric objects.

This iterable does not memoize. Callers who need to traverse the list multiple times, or who need to randomly access elements of the list, should use toList on this object.
