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
countClosedNeighbors(int x, int y) int
The number of cardinal neighbors of the tile at column x row y that are closed (not open)
countNeighbors(int x, int y) int
The number of cardinal neighbors of the tile at column x row y
countOpenNeighbors(int x, int y) int
The number of cardinal neighbors of the tile at column x row y that are open
elementAt(int index) → T
Returns the indexth element.
inherited
every(bool test(T element)) bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(T element)) Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(T element), {T orElse()?}) → T
The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, T element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<T> other) Iterable<T>
Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(T element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
get(int x, int y) → T
Get the tile at column x row y
isOpen(int x, int y) bool
true if the tile at column x row y is a valid position and is open
join([String separator = ""]) String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(T element), {T orElse()?}) → T

inherited
reduce(T combine(T value, T element)) → T
