Migrating to material3 1.5.0 — deprecations

Short answer: the most common warnings after upgrading to 1.5.0-beta02 come from four APIs:

• ListItem(headlineContent = …) → put the headline in the trailing content lambda
• the old SearchBar/DockedSearchBar → SearchBar(state, inputField) with an expanded search bar
• TopSearchBar → AppBarWithSearch
• non-state Slider overloads → Slider(state, …)

ListItem

@Composable
fun WifiRow(network: String, onClick: () -> Unit) {
    // 1.5.0: the headline is the trailing content lambda. ListItem(headlineContent = …) is deprecated.
    // The onClick overload makes the whole row clickable with the right semantics.
    ListItem(onClick = onClick, supportingContent = { Text(network) }) {
        Text("Wi-Fi")
    }
}

SearchBar

@Composable
fun AppSearch(suggestions: (String) -> List<String>, onSearch: (String) -> Unit) {
    // State-based search bar. The old SearchBar(query, onQueryChange, active, …) is deprecated.
    val searchBarState = rememberSearchBarState()
    val textFieldState = rememberTextFieldState()
    val scope = rememberCoroutineScope()
    val inputField = @Composable {
        SearchBarDefaults.InputField(
            textFieldState = textFieldState,
            searchBarState = searchBarState,
            onSearch = { query ->
                onSearch(query)
                scope.launch { searchBarState.animateToCollapsed() }
            },
            placeholder = { Text("Search") },
        )
    }

    SearchBar(state = searchBarState, inputField = inputField)
    ExpandedFullScreenSearchBar(state = searchBarState, inputField = inputField) {
        LazyColumn {
            items(suggestions(textFieldState.text.toString())) { suggestion ->
                ListItem(
                    onClick = {
                        textFieldState.setTextAndPlaceCursorAtEnd(suggestion)
                        onSearch(suggestion)
                        scope.launch { searchBarState.animateToCollapsed() }
                    },
                ) { Text(suggestion) }
            }
        }
    }
}
