# PathMetrics class

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.

When iterating across a PathMetrics' contours, the PathMetric objects are only valid until the next one is obtained.

## Methods

any(bool test(E element)) → bool
  Checks whether any element of this iterable satisfies `test`. [...]
  inherited
cast<R>() → Iterable<R>
  Provides a view of this iterable as an iterable of `R` instances. [...]
  inherited
contains(Object element) → bool
  Returns true if the collection contains an element equal to `element`. [...]
  inherited
elementAt(int index) → PathMetric
  Returns the `index`th element. [...]
  inherited
every(bool test(E element)) → bool
  Checks whether every element of this iterable satisfies `test`. [...]
  inherited
expand<T>(Iterable<T> f(E element)) → Iterable<T>
  Expands each element of this Iterable into zero or more elements. [...]
  inherited
firstWhere(bool test(E element), { PathMetric orElse() }) → PathMetric
  Returns the first element that satisfies the given predicate `test`. [...]
  inherited
fold<T>(T initialValue, T combine(T previousValue, E element)) → T
  Reduces a collection to a single value by iteratively combining each element of the collection with an existing value [...]
  inherited
followedBy(Iterable<PathMetric> other) → Iterable<PathMetric>
  Returns the lazy concatentation of this iterable and `other`. [...]
  inherited
forEach(void f(E element)) → void
  Applies the function `f` to each element of this collection in iteration order.
  inherited
join([String separator = "" ]) → String
  Converts each element to a String and concatenates the strings. [...]
  inherited
lastWhere(bool test(E element), { PathMetric orElse() }) → PathMetric
  Returns the last element that satisfies the given predicate `test`. [...]
  inherited
map<T>(T f(E e)) → Iterable<T>
  Returns a new lazy Iterable with elements that are created by calling `f` on each element of this `Iterable` in iteration order. [...]
  inherited
noSuchMethod(Invocation invocation) → dynamic
  Invoked when a non-existent method or property is accessed. [...]
  inherited
reduce(PathMetric combine(E value, E element)) → PathMetric
  Reduces a collection to a single value by iteratively combining elements of the collection using the provided function. [...]
  inherited
singleWhere(bool test(E element), { PathMetric orElse() }) → PathMetric

  inherited
skipWhile(bool test(E value)) → Iterable<PathMetric>
