# insertAdjacentHtml method

void insertAdjacentHtml(

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

})
override

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 = '<div class="something">content</div>';
        // Inserts as the first child
        document.body.insertAdjacentHtml('afterBegin', html);
        var createdElement = document.body.children[0];
        print(createdElement.classes[0]); // Prints 'something'
