any(
bool test(T element)) → bool -
Checks whether any element of this iterable satisfies
test
.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 -

int x, int y) → int -
The number of cardinal neighbors of the tile at column
x
rowy
that are open -
elementAt(
int index) → T -
Returns the
index
th 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 -

action
on each element of this iterable in iteration order.inherited -
get(
int x, int y) → T -
Get the tile at column
x
rowy
-
isOpen(
int x, int y) → bool -
true if the tile at column
x
rowy
is a valid position and is open -
join(
[String separator = ""]) → String -
Converts each element to a String and concatenates the strings.
inherited
-
