# Font Size

Within the editor toolbar, a drop-down with font-sizing capabilities is available. This can be enabled or disabled with `showFontSize`.

When enabled, the default font-size values can be modified via *optional* `fontSizeValues`. Accepts a `Map<String, String>` consisting of a `String` title for the font size and a `String` value for the font size. Example:

```dart
fontSizeValues: const {'Small': '8', 'Medium': '24.5', 'Large': '46'}
```

Font size can be cleared with a value of `0`, for example:

```dart
fontSizeValues: const {'Small': '8', 'Medium': '24.5', 'Large': '46', 'Clear': '0'}
```
