*** ** * ** ***

A serializer for `https://developer.android.com/reference/android/util/Size.html`. This serializer uses `https://developer.android.com/reference/androidx/savedstate/SavedState`'s API directly to save/load a `https://developer.android.com/reference/android/util/Size.html`.

Note that this serializer should be used with `https://developer.android.com/reference/androidx/savedstate/serialization/SavedStateEncoder` or `https://developer.android.com/reference/androidx/savedstate/serialization/SavedStateDecoder` only. Using it with other Encoders/Decoders may throw `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-illegal-argument-exception/index.html`.

```kotlin
import androidx.savedstate.serialization.serializers.SizeSerializer

@Serializable
data class MyModel(@Serializable(with = SizeSerializer::class) val size: android.util.Size)
```
