# createElement method Null safety

Element createElement (

1. String tagName,
2. [String? typeExtension]

)

## Implementation

    @pragma('dart2js:tryInline') // Almost all call sites have one argument.
    Element createElement(String tagName, [String? typeExtension]) {
      return (typeExtension == null)
          ? _createElement_2(tagName)
          : _createElement(tagName, typeExtension);
    }
