inherited
clone() → VecKeyPoint
override
contains(Object? element) → bool

inherited
every(bool test(KeyPoint element)) → bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(KeyPoint element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(KeyPoint element), {KeyPoint orElse()?}) → KeyPoint
The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, KeyPoint element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<KeyPoint> other) → Iterable<KeyPoint>

inherited
lastWhere(bool test(KeyPoint element), {KeyPoint orElse()?}) → KeyPoint
The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(KeyPoint e)) → Iterable<T>
The current elements of this iterable modified by toElement.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reattach({Pointer<VecKeyPoint>? newPtr}) → void
override
reduce(KeyPoint combine(KeyPoint value, KeyPoint element)) → KeyPoint
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
