# insertAdjacentHtml method Null safety

void insertAdjacentHtml (

1. String where,
2. String html,
3. {NodeValidator? validator,
4. NodeTreeSanitizer? treeSanitizer}

)

Parses text as an HTML fragment and inserts it into the DOM at the specified location.

The `where` parameter indicates where to insert the HTML fragment:

- 'beforeBegin': Immediately before this element.

- 'afterBegin': As the first child of this element.

- 'beforeEnd': As the last child of this element.

- 'afterEnd': Immediately after this element.

  var html = '

  content
  '; // Inserts as the first child document.body.insertAdjacentHtml('afterBegin', html); var createdElement = document.body.children`0`; print(createdElement.classes`0`); // Prints 'something'

## Implementation

    void insertAdjacentHtml(String where, String html,
        {NodeValidator? validator, NodeTreeSanitizer? treeSanitizer}) {
      if (treeSanitizer is _TrustedHtmlTreeSanitizer) {
        _insertAdjacentHtml(where, html);
      } else {
        _insertAdjacentNode(
            where,
            createFragment(html,
                validator: validator, treeSanitizer: treeSanitizer));
      }
    }
