```kotlin
@ExperimentalFoundationStyleApi
class MutableStyleState
@RememberInComposition
constructor(override val interactionSource: InteractionSource?) : StyleState()
```
The state a style that can be updated to reflect the current state of a component. This value
should be created in a component and updated to select the style parameter to be set for the
component.
A component that uses an interaction source can create a `MutableStyleState` that observes the
interactions emitted to the interaction source.
## Functions
set
```kotlin
operator fun set(key: StyleStateKey, value: T)
```
Set the `value` of the `key` in the `StyleState`.
remove
```kotlin
fun remove(key: StyleStateKey)
```
Removes the `StyleStateKey` from the `StyleState`.
A `Style` will read the `StyleStateKey.defaultValue` for the `StyleStateKey` when the key is
not present in the `StyleState`.
Removing a key that is updated via an `InteractionSource` will no longer observe the
interaction source.
Predefined style keys, such as `StyleStateKey.Pressed` and `StyleStateKey.Hovered`, cannot be
removed from the set of keys and this will throw if removed.
