Methods

after(Iterable<E> sublist, {int skip = 0}) → List<E>?

Available on Iterable<E>, provided by the HeartIterableE extension

Returns everything after a given sublist: 1, 2, 3.after(1) returns 2, 3 1, 2, 3.after(1, 2) returns 3 1, 2, 3.after([]) returns 1, 2, 3

backwards() → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Reverses and returns a List.

before(Iterable<E> sublist, {int skip = 0}) → List<E>?

Available on Iterable<E>, provided by the HeartIterableE extension

Returns everything before a given sublist: 1, 2, 3, 3.before(3) returns 1, 2 1, 2, 3, 3.before(3, 3) returns 1, 2 1, 2, 3, 3.before(1) returns [] 1, 2, 3, 3.before([]) returns []

drop(int n) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Removes first n elements.

dropWhile(bool dropFunction(E sub)) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Removes elements until criteria not met.

elemIndices(E element) → List<int>

Available on Iterable<E>, provided by the HeartIterableE extension

Finds each index where element occurs.

filter(bool filterFunction(E element)) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Removes elements that don't meet criteria.

group() → List<List<E>>

Available on Iterable<E>, provided by the HeartIterableE extension

Items are in the same sublist if they are equal to the one next to it.

groupBy(bool groupFunction(dynamic a, dynamic b)) → List<List<E>>

Available on Iterable<E>, provided by the HeartIterableE extension

Items are in the same sublist if they meet the criteria that compares consecutive elements.

head() → E?

Available on Iterable<E>, provided by the HeartIterableE extension

Returns the first element.

indices(Iterable<E> sublist, {bool exclusive = false}) → List<int>

Available on Iterable<E>, provided by the HeartIterableE extension

Finds each index where sublist occurs. Deprecated 'elemIndices' only searched for one element and not sublist.

inits() → List<List<E>>

Available on Iterable<E>, provided by the HeartIterableE extension

Returns a List of Lists by adding one element at a time, starting from the beginning.

interleave(Iterable<E> it) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Combines elements by taking turns. First element in original iterable is the first element of the result.

intersect(Iterable<E> input) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Keeps all values that are also in input String, using deepEquals.

intersperse(E element) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Inserts an element in between each element.

nub([Iterable<E>? it]) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Removes duplicates by using deepEquals.

replace(Iterable<E> from, [Iterable<E> to = const [], int? count]) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Successor to 'replaceFirst' and 'replaceAll' 1, 1, 1.replace(1, 3) returns 3, 3, 3 1, 1, 1, 1.replace(1, 1, 3) returns 3, 3

replaceAll(E from, [dynamic to]) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Similar to .replaceAll for Strings.

replaceFirst(E from, [dynamic to]) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Similar to .replaceFirst for Strings.

riffleIn() → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Splits into two and uses interleave to combine, second half first.

riffleOut() → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Splits into two and uses interleave to combine.

shuffled([Random? random]) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Returns a shuffled List.

splitAt(int n) → List<List<E>>

Available on Iterable<E>, provided by the HeartIterableE extension

Splits into two Lists after first n elements.

startsWith(Iterable<E> sublist) → bool

Available on Iterable<E>, provided by the HeartIterableE extension

Equivalent to Dart's .startsWith for String 1, 2, 3.startsWith(1) returns true 1, 2, 3.startsWith(1, 2) returns true 1, 2, 3.startsWith(3) returns false

subtract(Iterable<E> sublist) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Removes elements one at a time, using deepEquals.

subtractAll(Iterable<E> sublist) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Removes all elements if they are in sublist.

tail() → List<E>?

Available on Iterable<E>, provided by the HeartIterableE extension

Removes the first element, keeps the "tail".

tails() → List<List<E>>

Available on Iterable<E>, provided by the HeartIterableE extension

Returns a List of Lists by removing one element at a time, starting from the beginning.

toStringList() → List<String>

Available on Iterable<E>, provided by the HeartIterableE extension

Converts all elements to Strings.

union(Iterable<E> l) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Adds elements from input that aren't in original value.

Operators

operator *(int n) → List<E>

Available on Iterable<E>, provided by the HeartIterableE extension

Repeat elements n times.
