chunk(List list, [int size = 1]) → List

Creates an list of elements split into groups the length of size. If list can't be split evenly, the final chunk will be the remaining elements. Example

compact(List list) → List

Creates an list with all falsey values removed. The values false, null, 0, "", and NaN are falsey. Example

drop(List list, [int n = 1]) → List

Creates a slice of list with n elements dropped from the beginning.

dropRight(List list, [int n = 1]) → List

Creates a slice of list with n elements dropRightped from the beginning.

duplicate(List list) → List

Find duplicate items in an list

fill(List list, dynamic value, [int start = 0, int? end]) → List

Fills elements of list with value from start up to, but not including, end. Example

findIndex(List list, dynamic element) → int

This method uses dart's default List.indexOf Example

findLastIndex(List list, dynamic element) → int

This method finds the item in the list from right / last using dart's List.indexOf() method Example

flatten(List list) → List

Flatten a list

head(List list) → dynamic

Finds the first element in the list Uses dart's List.first property Example

initial(List list) → List

Gets all but the last element of list. Example

intersect(List<List> arrays) → dynamic

Creates an list of unique values that are included in all given arrays Example

join(List list, [String separator = ',']) → String

Converts all elements in list into a string separated by separator. Uses dart's List.join() Example

last(List list) → dynamic

map(List list, dynamic iteratee(dynamic element, int index, List list)) → List

Creates an list of values by running each element of list thru iteratee. The iteratee is invoked with three arguments: (value, index, list).

nth(List list, int n) → dynamic

Gets the element at index n of list. If n is negative, the nth element from the end is returned. Example

pairs(List pairs) → Map

This method returns an object composed from key-value pairs. Example

slice(List list, [int start = 0, int? end]) → List

Creates a slice of list from start up to, but not including, end. Example

sortedIndex(List list, dynamic value) → int

Uses a binary search to determine the lowest index at which value should be inserted into list in order to maintain its sort order. Returns the index at which value should be inserted into list. Example

tail(List list) → List

Gets all but the first element of list. Example

take(List list, [int n = 1]) → List

Creates a slice of list with n elements taken from the beginning. Uses dart's native List.take(n) method Example

takeRight(List list, [int n = 1]) → List

Creates a slice of list with n elements taken from the end. Example
