Functions

cross<T>(Iterable<Iterable<T>> iterables) → List<List<T>>

Returns the Cartesian product of the specified iterables.

crossWith<T, R>(Iterable<Iterable<T>> iterables, R reducer(List<T>)) → List<R>

Returns the Cartesian product of the specified iterables, applying the specified reducer function to each combination of elements.

filter<T>(Iterable<T> iterable, bool test(T)) → List<T>

Returns a new list containing the values from iterable, in order, for which the given test function returns true.

map<T, R>(Iterable<T> iterable, R mapper(T)) → List<R>

Returns a new list containing the mapped values from iterable, in order, as defined by given mapper function.

merge<T>(Iterable<Iterable<T>> iterables) → List<T>

Merges the specified iterable of iterables into a single list.

pairs<T>(Iterable<T> iterable) → List<(T, T)>

Returns a list of pairs from consecutive values of the provided iterable.

pairsWith<T, R>(Iterable<T> iterable, R reducer(T, T)) → List<R>

Returns a list of values yielded by the reducer function applied to each pair of consecutive elements from the provided iterable.

transpose<T>(Iterable<Iterable<T>> matrix) → List<List<T>>

Returns a list of lists, where the ith list contains the ith element from each of the iterables in the matrix.
