```kotlin
@ExperimentalComposeRuntimeApi
public class SnapshotFlowManager
```


Orchestrates the observation of `Snapshot` state for `snapshotFlow`s that are collected on the
same thread.

Once a `SnapshotFlowManager` is no longer needed, its `dispose` method should be called.

It is not safe to share a `SnapshotFlowManager` instance across two `snapshotFlow`s that collect
in parallel on two different threads, but it is not a problem for a thread to run apply observers
in parallel with another thread collecting a `snapshotFlow`.


## Functions

```kotlin
public fun dispose()
```


Disposes of this manager. Disposing of a manager disconnects it from the `Snapshot` system,
rendering it incapable of handling any subscriptions.

If this method is called after this manager has been disposed of, an `IllegalStateException`
will be thrown.
