any method

bool any(
  1. bool test(
    1. K,
    2. V
    )
)

Returns true if the map contains any entry matching the predicate.

Example:

{'a': 1, 'b': 2}.any((k, v) => v > 1); // true

Implementation

bool any(bool Function(K, V) test) {
  for (final entry in entries) {
    if (test(entry.key, entry.value)) return true;
  }
  return false;
}
