Add MutableStateSerializer for serializing MutableState
Expand for full commit details
Add `MutableStateSerializer` for serializing `MutableState`
- Introduced an inline `MutableStateSerializer` function to infer and retrieve the appropriate `KSerializer` for `MutableState` of a serializable type.
- Added an overload of `MutableStateSerializer` that accepts an explicit `KSerializer` for the wrapped type, allowing for customizing the `KSerializer`.
- Implemented `MutableStateSerializerImpl`, a private class that handles the serialization and deserialization logic for `MutableState`, delegating inner value processing to the provided `KSerializer`.
- Only `KSerializer<MutableState<T>>` is exposed; the `MutableStateSerializerImpl` remains private.
RelNote: "Add `MutableStateSerializer` for serializing `androidx.compose.runtime.MutableState`."

Move MutableStateSerializer to savedstate-compose
Expand for full commit details
Move `MutableStateSerializer` to `savedstate-compose`
- This change moves `MutableStateSerializer` from `lifecycle-viewmodel-compose` to `savedstate-compose`. This corrects its previous misplacement and aligns with the design outlined in go/savedstate-compose, which specifies that all `savedstate-compose` related APIs should reside within the `savedstate-compose` module.
RelNote: "Move `MutableStateSerializer` to `savedstate-compose`."

Description
saveablehas built-in support for Compose'sMutableState, supporting this use case:It does this by providing an overloaded function that handles
MutableState.valueand serializes it when needed.To help people migrate from
saveabletosaved, we want to supportMutableStatein our KotlinX serialization support.While working on
getMutableState, I experimented with this and created a naiveKSerializerimplementation to handleMutableState.Here’s what it could look like:
For serialization, we'd use
(value as MutableState<T>).value+valueSerializerto serialize the content. Deserialization works in the opposite direction.Here’s a usage example:
However, calling this without the serializer would cause an exception.
Our variant should work like
saveable: ifT(the generic type insaved) is serializable, it should work without needing the serializer.The goal is to find the best way to support
MutableStateinsaved(using aKSerializer, overloads, or another method).Related to
