firstWhere(bool test(T value), {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
