Interface
Common
```kotlin
interface TextAutoSize
```
Interface used by Text composables to override text size to automatically grow or shrink text to
fill the layout bounds.
## Functions
getFontSize
```kotlin
fun TextAutoSizeLayoutScope.getFontSize(
constraints: Constraints,
text: AnnotatedString,
): TextUnit
```
Calculates font size and provides access to `TextAutoSizeLayoutScope`, which offers
`TextAutoSizeLayoutScope.performLayout` to lay out the text and use the measured size.
#### Returns
| | |
| --- | --- |
| | The derived optimal font size |
equals
```kotlin
override fun equals(other: Any?): Boolean
```
This type is used in performance-sensitive paths and requires providing equality guarantees.
Using a data class is sufficient. Singletons may implement this function with referential
equality (`this === other`). Instances with no properties may implement this function by
checking the type of the other object.
#### Returns
| | |
| --- | --- |
| | true if both AutoSize instances are identical. |
hashCode
```kotlin
override fun hashCode(): Int
```
This type is used in performance-sensitive paths and requires providing identity guarantees.
#### Returns
| | |
| --- | --- |
| | a unique hashcode for this AutoSize instance. |
