sourceInformationMarkerStart

@ComposeCompilerApi
public fun sourceInformationMarkerStart(composer: Composer, key: Int, sourceInformation: String)

A Compose internal function. DO NOT call directly.

Records the start of a source information marker that can be used for tooling to determine the source location of the corresponding composable function that otherwise don't require tracking information such as ReadOnlyComposable functions. By default, this function is declared as having no side-effects. It is safe for code shrinking tools (such as R8 or ProGuard) to remove it.

Important that both sourceInformationMarkerStart and sourceInformationMarkerEnd are removed together or both kept. Removing only one will cause incorrect runtime behavior.
