# SplayTreeMap<K, V>.fromIterables constructor

SplayTreeMap<K, V>.fromIterables(

1. Iterable<K> keys,
2. Iterable<V> values, [
3. int compare(
   1. K key1,
   2. K key2
   )?,
4. bool isValidKey(
   1. dynamic
   )?,

])

Creates a SplayTreeMap associating the given `keys` to `values`.

This constructor iterates over `keys` and `values` and maps each element of `keys` to the corresponding element of `values`.

If `keys` contains the same object multiple times, the last occurrence overwrites the previous value.

It is an error if the two Iterables don't have the same length. Example:

    final keys = ['1', '2', '3', '4'];
    final values = ['A', 'B', 'C', 'D'];
    final mapFromIterables = SplayTreeMap.fromIterables(keys, values);
    print(mapFromIterables); // {1: A, 2: B, 3: C, 4: D}

## Implementation

    factory SplayTreeMap.fromIterables(
      Iterable<K> keys,
      Iterable<V> values, [
      int Function(K key1, K key2)? compare,
      bool Function(dynamic potentialKey)? isValidKey,
    ]) {
      SplayTreeMap<K, V> map = SplayTreeMap<K, V>(compare, isValidKey);
      MapBase._fillMapWithIterables(map, keys, values);
      return map;
    }
