Returns true if the provided predicate function returns true for at least one element in a collection, false otherwise.

Use Iterable.any() to test if any elements in the collection return true based on fn.

代码实现

bool some<T>(Iterable<T> itr, bool Function(T) fn) {
  return itr.any(fn);
}

使用样例

some([0, 1, 2, 0], (x) => x >= 2); // true
