What is map.fromIterables() method in Dart?

fromIterables() is a method in Dart that creates a Map instance from an Iterable.

Syntax

``` map.remove(key, value) ``` >`map` is the name of the map.

Parameters

The `map.fromIterables()` method requires the `key` and `value` to create a `map`.

You must pass key and value parameters to determine what should be the key and value.

Return value

The Dart method `map.fromIterables()` iterates over `keys` and `values`. It maps each element of the `keys` to the corresponding elements of the `values`.

If there are multiple elements with the same key, the last occurrence of a key will be utilized.

Code

The following code illustrates the fromIterable() method’s use in Dart:

void main() {
  // Creating iterables
  List<String> numbers = ['five', 'three', 'seven', 'one'];
  List<String> fruits = ['Apple', 'Orange', 'Lemon', 'Pawpaw'];
  // Creating a map from the iterables
  // using fromIterables() method
  Map<String, String> map = new Map.fromIterables(numbers, fruits);
  print(map);
}

Note: Both Iterables must have the same length.
