FlowPreview
@Target(allowedTargets = [AnnotationTarget.CLASS, AnnotationTarget.FUNCTION, AnnotationTarget.TYPEALIAS, AnnotationTarget.PROPERTY] )
Marks Flow-related API as a feature preview.
Flow preview has no backward compatibility guarantees, including both binary and source compatibility. Its API and semantics can and will be changed in next releases.
Feature preview can be used to evaluate its real-world strengths and weaknesses, gather and provide feedback. According to the feedback, Flow will be refined on its road to stabilization and promotion to a stable API.
The best way to speed up preview feature promotion is providing the feedback on the feature.
