# Breaking: #101133 - IconFactory->getIcon() signature change {#breaking-101133-1687875354}

See [forge#101133](https://forge.typo3.org/issues/101133)

## Description {#description}

The public method `getIcon()` in `\TYPO3\CMS\Core\Imaging\IconFactory`
has changed its 4th parameter, in order to prepare the removal
of class `\TYPO3\CMS\Core\Type\Icon\IconState`.

## Impact {#impact}

Custom extensions extending the `getIcon()` method of class
`\TYPO3\CMS\Core\Imaging\IconFactory` not having the same signature
will fail with a PHP fatal error.

## Affected installations {#affected-installations}

Custom extensions extending the `getIcon()` method from class
`\TYPO3\CMS\Core\Imaging\IconFactory`.

## Migration {#migration}

Adapt the 4th parameter of `getIcon()` to be of type
`\TYPO3\CMS\Core\Type\Icon\IconState|IconState $state = null`

In addition, adapt the code in the body of the method.
