```

*** ** * ** ***

Tooling can override `https://developer.android.com/reference/kotlin/androidx/compose/runtime/package-summary#mutableStateOf(kotlin.Any,androidx.compose.runtime.SnapshotMutationPolicy)` in `https://developer.android.com/reference/kotlin/androidx/compose/runtime/Composable` with `https://developer.android.com/reference/kotlin/androidx/compose/ui/tooling/animation/ToolingState`. `https://developer.android.com/reference/kotlin/androidx/compose/runtime/Composable` should declare a state, which could be private:

```kotlin
val toolingOverride = remember { mutableStateOf<State?>(null) }
```

Tooling overrides `toolingOverride` with

```kotlin
toolingOverride.value = ToolingState(default)
```
