Build a Compose Rating Form with Validated Submission State

Design an Android Compose rating form. The user chooses one to five stars, enters a written review, and presses Submit. The button is enabled only after both a rating and review have been provided. After a successful submission, show a different UI confirming that the review was submitted. ### Constraints & Assumptions - Rating values are integers from one through five. - Clarify whether whitespace-only text counts as a review; this practice solution treats it as missing. - Do not show successful submission merely because a network request started. - Define loading, failure, and repeated-click behavior. ### Clarifying Questions to Ask - Should the draft survive screen recreation or process recreation? - Can the user edit while submission is in progress? - What validation and duplicate-submission guarantees does the server provide? ```hint The enabled state can be derived from form state; it does not need a separate mutable Boolean that can drift out of sync. ``` ### What a Strong Answer Covers Model rating, text, submission progress, errors, and confirmed completion in one coherent state flow. Explain state hoisting, event callbacks, derived validation, asynchronous submission, and accessible star selection. ### Follow-up Questions - What happens if the request fails after the user taps Submit? - How do you prevent a recomposition from submitting again? - How would you restore the draft after recreation?
