    "system_prompt": "name compose-focus-navigation description Use when writing or reviewing Jetpack Compose UI for TV, keyboard, desktop, accessibility focus, D-pad navigation, FocusRequester, focusProperties, key events, or initial focus behavior. Compose: focus navigation Core principle Focus is stateful UI behavior: make targets and exceptional edges explicit, then drive and verify it through the user's keyboard, D-pad, or remote input. Procedure Start with components that already participate in focus. Add a hook only for a requested behavior: Need Add Normal button/text field/clickable focus Nothing extra; use the focusable component Programmatic initial/restored focus FocusRequester + Modifier.focusRequester(...) Visual or state reaction to focus changes Modifier.onFocusChanged { ... } Custom interactive surface that is not already focusable Modifier.focusable() plus role/semantics as appropriate Request initial or restored focus from LaunchedEffect , keyed to the condition that makes the target present. For lazy content, keep requesters by stable item id and request only after the item is composed. Inside AnimatedContent , use the content lambda's target consistently for rendered identity, tags, requester ownership, and the effect key; captured outer state gives outgoing and incoming content the same identity. Keep default spatial search unless a concrete edge, jump, or trap is wrong. Encode only those exceptions with focusProperties . Handle keys only for behavior that is not normal click or traversal. Consume exactly the handled event; throttle rapid D-pad work at its expensive owner, not across the screen. Restore by semantic identity after refresh: retain the focused id when it exists, otherwise choose a deterministic fallback. Test with one concrete key/D-pad interaction and focused semantics. When the behavior under review is user-triggered, do not substitute direct state mutation or leave the input conditional. Use screenshots only for the focus appearance. Finish when all intentional targets and exceptional edges are encoded, loading/refresh behavior has a stable focus policy, and tests use the same input model as users. For example, request and observe focus only when both behaviors are required: val requester = remember { FocusRequester() } Button( onClick = onClick, modifier = Modifier .focusRequester(requester) .onFocusChanged { state -> isFocused = state.isFocused }, ) { Text( \"Play\" ) } Call focus requests from an effect, not the composable body: val initialFocus = remember { FocusRequester() } LaunchedEffect(initialFocus) { initialFocus.requestFocus() } If the target appears after loading, key the request to the condition: LaunchedEffect(items.isNotEmpty()) { if (items.isNotEmpty()) { firstItemRequester.requestFocus() } } Use focusProperties only when default spatial search is wrong: Modifier.focusProperties { up = headerRequester down = firstRowRequester left = FocusRequester.Cancel } Too many hard-coded links create stale focus graphs. For special key behavior, consume only the handled event: Modifier.onPreviewKeyEvent { event -> if (event.type == KeyEventType.KeyUp && event.key == Key.Back) { onBack() true } else { false } } Test focus through user input: composeTestRule.onNodeWithTag( \"screen\" ).performKeyInput { pressKey(Key.DirectionDown) } composeTestRule.onNodeWithTag( \"play-button\" ).assertIsFocused() Broader test-shape choices are in Compose UI testing patterns .",
