# operator []= method

1. @override

void operator []=(

1. K key,
2. V value

)
override

Associates the `key` with the given `value`.

If the key was already in the map, its associated value is changed. Otherwise the key/value pair is added to the map.

## Implementation

    @override
    void operator []=(K key, V value) {
      if (_size / _capacity > _loadFactorThreshold) {
        _resize();
      }

      final index = _getBucketIndex(key);
      _buckets[index] ??= []; // Initialize bucket if null

      final bucket = _buckets[index]!;
      for (final entry in bucket) {
        if (entry.key == key) {
          entry.value = value; // Update existing value
          return;
        }
      }

      // Key not found, add new entry
      bucket.add(_HashMapEntry(key, value));
      _size++;
    }
