chore(docs): Code Documentation for feature/notification module #2987
Conversation
WalkthroughA notification feature module was implemented comprising three main components: a composable-based UI screen with breakdown into content and item components, a ViewModel extending the base class with notification management flows (load, refresh, dismiss) and network monitoring, and navigation helpers to integrate the screen into the app's navigation graph.

203-203: Fix: rememberSaveable needs a key to prevent state misassignment.The
rememberSaveablecall doesn't provide a key, so saved state is keyed by composition position (the item's index in the LazyColumn). When notifications are reordered (e.g., after sorting unread first) or the list changes, the savedisReadstate can be restored for the wrong notification, showing incorrect read/unread status.Option 1 (Quick fix): Add a key parameter:
- val isRead = rememberSaveable { mutableStateOf(notification.isRead()) } + val isRead = rememberSaveable(key = notification.id.toString()) { + mutableStateOf(notification.isRead()) + }Option 2 (Recommended): Remove local state entirely and derive it directly from the notification object, since the ViewModel already tracks read status:
- val isRead = rememberSaveable { mutableStateOf(notification.isRead()) } + val isRead = remember(notification) { notification.isRead() }Then update the dismiss logic:
- if (!isRead.value) { + if (!isRead) { MifosTextButton( content = { Text(stringResource(Res.string.dialog_action_ok)) }, onClick = { - isRead.value = true dismissNotification(notification) }, ) }Note: With Option 2, the button won't immediately hide when clicked (it will wait for the state to update via the ViewModel). If immediate UI feedback is desired, keep the mutable state but add the key parameter (Option 1).
237-240: I need to investigate further. The key finding is thatupdateReadStatusis completely commented out. Let me gather more context:I need to locate the
dismissNotificationfunction and understand the full context. Let me run a final verification script:Fix non-functional repository implementation and add error handling for dismiss action.
The
dismissNotificationcall on line 239 has two critical issues:
Non-functional implementation: The
updateReadStatusmethod inNotificationRepositoryImpis completely commented out, so dismissing a notification never persists to the database.Missing error handling: Suspend functions should use try-catch blocks to handle exceptions. The optimistic UI update (line 238) occurs before the async call with no error handling. If the repository operation fails, the notification appears dismissed locally but remains in the database, creating a stale state.
Required actions:
- Uncomment or complete the
updateReadStatusimplementation incore/data/src/commonMain/kotlin/org/mifos/mobile/core/data/repositoryImpl/NotificationRepositoryImp.kt- Wrap the dismiss operation in try-catch to store previous state and rollback the UI update if the operation fails

80-82: Optional: Remove no-op DataState.Loading branch.Line 81 evaluates to
Loadingbut doesn't update_notificationUiState. Since the state was already set toLoadingon line 67, this branch is a no-op and could be removed for clarity.is DataState.Error -> { _notificationUiState.value = NotificationUiState.Error(notifications.message) } - DataState.Loading -> { - Loading - } is DataState.Success -> { _isRefreshing.emit(false)

54-82: Documentation and implementation look good!The entry point composable is well-documented and correctly delegates to the private overload after collecting state from the ViewModel.
84-147: Well-structured state handling!The documentation clearly explains the UI states, and the implementation correctly handles all variants of NotificationUiState with appropriate components.
149-188: Pull-to-refresh implementation is correct!The documentation accurately describes the refresh functionality, and the implementation properly uses PullToRefreshBox with LazyColumn.
feature/notification/src/commonMain/kotlin/org/mifos/mobile/feature/notification/navigation/NotificationNavigation.kt (1)
21-49: Excellent navigation documentation!All navigation components are well-documented and follow standard patterns. The route definition, navigation function, and destination builder are all correctly implemented.
feature/notification/src/commonMain/kotlin/org/mifos/mobile/feature/notification/NotificationViewModel.kt (4)
26-60: Well-documented ViewModel initialization!The class documentation is comprehensive, and the initialization logic correctly deletes old notifications before loading current ones. The network monitoring setup with
stateInis also appropriate.
96-102: Clean refresh implementation!The refresh function is well-documented and correctly implemented with the refreshing state management.
115-126: Perfect sorting implementation!The documentation clearly describes the sorting logic (unread first, then most recent), and the implementation correctly uses
compareByDescendingwiththenByDescending.
129-154: Comprehensive UI state documentation!All UI state variants are well-documented with clear descriptions of when each state is used and what data they contain.
