React Native: Support shuffle questions and shuffle options in surveys

[adboio]

🚨 IMPORTANT

This issue is likely user-facing in the main PostHog app, see surveyVersionRequirements.ts. If you delete or close this issue, be sure to update the version requirements list here.

Summary

The posthog-react-native SDK does not support shuffling questions or shuffling choice options in surveys. Both features have explicit // TODO comments with commented-out implementation code in packages/react-native/src/surveys/surveys-utils.ts.

Current State

• getDisplayOrderQuestions() has // TODO: shuffle questions and returns unshuffled questions
• getDisplayOrderChoices() has // TODO: shuffle choices and returns unshuffled choices
• The commented-out code shows the intended implementation pattern

Expected Behavior

• When survey.appearance.shuffleQuestions is true, questions should be presented in a randomized order (unless enable_partial_responses is true)
• When question.shuffleOptions is true on a choice question, the choices should be randomized (keeping open-ended choice at end)

Reference Implementation

See posthog-js browser: packages/browser/src/extensions/surveys/surveys-extension-utils.tsx

• getDisplayOrderQuestions() for question shuffling
• getDisplayOrderChoices() for option shuffling
