Function
maxLength
Common
```kotlin
fun InputTransformation.maxLength(maxLength: Int): InputTransformation
```
Returns `InputTransformation` that rejects input which causes the total length of the text field
to be more than `maxLength` characters.
This transformation also sets the maximum text length for accessibility services. When using an
`OutputTransformation` that adds decorating characters, the announced maximum length may need to
be adjusted to account for those characters. See the linked sample for an example of a custom
`maxLength` filter that does this.
