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.

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.

Methods

any(bool test(PathMetric element)) → bool
Checks whether any element of this iterable satisfies test.
inherited
cast<R>() → Iterable<R>
A view of this iterable as an iterable of R instances.
inherited
contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
elementAt(int index) → PathMetric
Returns the indexth element.
inherited
every(bool test(PathMetric element)) → bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(PathMetric element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(PathMetric element), {PathMetric orElse()?}) → PathMetric
The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, PathMetric 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>

inherited
forEach(void action(PathMetric element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
join([String separator = ""]) → String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(PathMetric element), {PathMetric orElse()?}) → PathMetric
The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(PathMetric e)) → Iterable<T>

inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reduce(PathMetric combine(PathMetric value, PathMetric element)) → PathMetric
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
singleWhere(bool test(PathMetric element), {PathMetric orElse()?}) → PathMetric
The single element that satisfies test.
inherited
skip(int count) → Iterable<PathMetric>
