rememberSerializable

@Composable
inline fun <T : Any> rememberSerializable(
    vararg inputs: Any?,
    configuration: SavedStateConfiguration = DEFAULT,
    noinline init: () -> T
): T

Remember the value produced by init, and persist it across activity or process recreation using a KSerializer for saving and restoring via the saved instance state mechanism.

This function automatically finds a KSerializer for the reified type T, making it a convenient way to use rememberSaveable with types that are Serializable.

This behaves similarly to remember, but will survive configuration changes (such as screen rotations) and process death by saving the value into the instance state.

import androidx.compose.runtime.saveable.rememberSerializable

val holder = rememberSerializable(serializer = HolderSerializer) { Holder(0) }

@Composable
inline fun <T : Any> rememberSerializable(
    vararg inputs: Any?,
    configuration: SavedStateConfiguration = DEFAULT,
    noinline init: () -> MutableState<T>
): MutableState<T>

Remember a MutableState produced by init, and persist it across activity or process recreation using a KSerializer from kotlinx.serialization.

This function automatically finds a KSerializer for the reified type T, making it a convenient way to use rememberSaveable with types that are Serializable.

This behaves similarly to remember, but the state will survive configuration changes (like screen rotations) and process recreation. It is designed for state types that cannot be stored in a Bundle directly but can be serialized.

import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.saveable.rememberSerializable

val holder =
    rememberSerializable(stateSerializer = HolderSerializer) { mutableStateOf(Holder(0)) }

@Composable
fun <T : Any> rememberSerializable(
    vararg inputs: Any?,
    serializer: KSerializer<T>,
    configuration: SavedStateConfiguration = DEFAULT,
    init: () -> T
): T

Remember the value produced by init, and persist it across activity or process recreation using a KSerializer for saving and restoring via the saved instance state mechanism.

This behaves similarly to remember, but will survive configuration changes (such as screen rotations) and process death by saving the value into the instance state using a serializer from Kotlinx Serialization.

The value will be serialized using the provided serializer, and the way it's saved can be customized using configuration.

If the type cannot be automatically handled by a default Saver, this overload provides a simpler and type-safe way to persist complex or custom types using Kotlinx Serialization.

val holder = rememberSerializable(serializer = HolderSerializer) { Holder(0) }

@Composable
fun <T : Any> rememberSerializable(
    vararg inputs: Any?,
    stateSerializer: KSerializer<T>,
    configuration: SavedStateConfiguration = DEFAULT,
    init: () -> MutableState<T>
): MutableState<T>

Remember the value produced by init, and save it across activity or process recreation using a KSerializer from kotlinx.serialization.

This behaves similarly to remember, but the value will survive configuration changes (like screen rotations) and process recreation by saving it in the instance state using a serialization-based mechanism.

This overload is intended for cases where the state type cannot be stored directly in a Bundle, but can be serialized with kotlinx.serialization.KSerializer. This is particularly useful for custom or complex data types that are @Serializable.

import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.saveable.rememberSerializable

val holder =
    rememberSerializable(stateSerializer = HolderSerializer) { mutableStateOf(Holder(0)) }
