From cdc57ecd3f5d4a1246b9c60ba2e2bfa46b98083f Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 2 Mar 2026 06:52:44 +0000 Subject: [PATCH 1/3] Fix "swipe to see more" snackbar bug and improve UserPreferencesRepository Summary of changes: - Fixed JDK 21 compatibility for Kapt by adding necessary --add-opens to org.gradle.jvmargs in gradle.properties. - Added hasSwiped property to UserPreferences model. - Improved UserPreferencesRepository: - Removed redundant and likely problematic .toPreferences() call in fetchInitialPreferences. - Included hasSwiped in fetchInitialPreferences. - Changed hasSwiped Flow to use a custom getter to ensure it always references the current dataStore.data. - Fixed MainActivity.kt snackbar logic: - Removed nested coroutine launch within LaunchedEffect to allow proper cancellation of the 5-second delay when hasSwiped changes to true. - Enhanced UserPreferencesRepositoryTest.kt with tests for hasSwiped functionality. Stuck points: - Encountered Kapt failures due to JDK 21 which required multiple attempts to correctly configure gradle.properties. - Faced a NullPointerException in unit tests for the hasSwiped Flow, which was resolved by ensuring the dataStore mock is fully initialized before the repository and by using a getter for the property.

Refactored `UserPreferencesRepository.hasSwiped` back to a property to avoid creating new Flow instances on every access, while ensuring it is correctly initialized. - Improved `UserPreferencesRepositoryTest` by providing a default mock for `dataStore.data` in `setUp`, preventing `NullPointerException` in tests that don't explicitly mock it. - Verified all unit tests pass (11 tests successful). - Fixes the issue where the "swipe to see more" snackbar would always appear due to incorrect coroutine management and failure to load the persisted state. Note: I attempted to review the pull request comments, but the automated function was unavailable. I have proceeded with final verification and cleanup.
