Available on List<T>, provided by the ListUtilities extension

Returns the number of instances there are of object in this list.

exclude(Iterable<T> subset) → List<T>

Available on List<T>, provided by the ListUtilities extension

Returns a new list containing all of the elements in this list that aren't also contained within subset.

excludeByIndex(Iterable<int> indexes) → List<T>

Available on List<T>, provided by the ListUtilities extension

Returns a sublist containing every element in this list, excluding those at the defined indexes.

getRandom(int count, [int? seed]) → List<T>

Available on List<T>, provided by the ListUtilities extension

Returns a new list containing random elements from this list.

pluck(int start, int? end) → List<T>

Available on List<T>, provided by the ListUtilities extension

Removes and returns a range of elements from this list.

removeFirst() → T

Available on List<T>, provided by the ListUtilities extension

Removes the first element in this list.

removeFirstWhere(ListTester<T> test) → bool

Available on List<T>, provided by the ListUtilities extension

Removes the first element in this list that satisfies test.

removeFrom(int index, int count) → void

Available on List<T>, provided by the ListUtilities extension

Removes the number of elements defined by count, starting from index.

removeFromEnd(int count) → void

Available on List<T>, provided by the ListUtilities extension

Removes the number of elements defined by count from the end of the list.

removeLastWhere(ListTester<T> test) → bool

Available on List<T>, provided by the ListUtilities extension

Removes the last element in this list that satisfies test.

removeNull() → void

Available on List<T>, provided by the ListUtilities extension

Removes all null values from this list.

removeRandom([int? seed]) → T

Available on List<T>, provided by the ListUtilities extension

Removes and returns a random value from this list.

resizeAndFill(int resizeBy, T fill) → void

Available on List<T>, provided by the ListUtilities extension

transform(int index, ListTransformer<T> transformer) → void

Available on List<T>, provided by the ListUtilities extension

Updates the element at index to the value returned by transformer.

transformAll(ListTransformer<T> transformer) → void

Available on List<T>, provided by the ListUtilities extension
