Range class - dart_essentials library

Constructors

Range(int a, [int? b, int? c]): safe constructor - returns empty range if arguments are invalid
factory
Range.empty(): empty range - same as range(0)
factory

Methods

any(bool test(int 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) → int: Returns the indexth element.
inherited
every(bool test(int element)) → bool: Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(int element)) → Iterable<T>: Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(int element), {int orElse()?}) → int: The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, int element)) → T: Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<int> other) → Iterable<int>: Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(int 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(int element), {int orElse()?}) → int: The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(int 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
reduce(int combine(int value, int element)) → int: Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
singleWhere(bool test(int element), {int orElse()?}) → int: The single element that satisfies test.
inherited
skip(int count) → Iterable<int>: Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(int value)) → Iterable<int>: Creates an Iterable that skips leading elements while test is satisfied.
inherited
take(int count) → Iterable<int>: Creates a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(int value)) → Iterable<int>: Creates a lazy iterable of the leading elements satisfying test.
inherited
toList({bool growable = true}) → List<int>: Creates a List containing the elements of this Iterable.
inherited
toSet() → Set<int>: Creates a Set containing the same elements as this iterable.
inherited
toString() → String: Returns a string representation of (some of) the elements of this.
override
where(bool test(int element)) → Iterable<int>: Creates a new lazy Iterable with all elements that satisfy the predicate test.
inherited
whereType<T>() → Iterable<T>: Creates a new lazy Iterable with all elements that have type T.

Operators

operator ==(Object other) → bool: The equality operator.
