I keep getting this error whenever I try to use a textfield in Compose, I have tried both Textfield implementations, ie one with a String value and TextFieldValue arguments but still get the error, I have also tried using var text = rememberSaveable{mutableStateOf("")} and var text by remember {mutableStateOf("")}. I have also tried hoisting the State which is what I wanted to do in the first place but still get the error

Here's the code

fun SearchAppBar(
    query: String,
    onQueryChanged: (String) -> Unit,
    onExecuteSearch: () -> Unit,
    scrollPosition: Int,
    selectedCategory: FoodCategory?,
    onSelectedCategoryChanged: (String) -> Unit,
    onCategoryChangePosition: (Int) -> Unit,
) {

    Surface(
        modifier = Modifier.fillMaxWidth(),
        color = Color.White,
        elevation = 8.dp,
    ) {
        Column {
            Row(
                modifier = Modifier.fillMaxWidth(),
            ) {
                TextField(
                    modifier = Modifier
                        .fillMaxWidth(.9f)
                        .padding(8.dp),
                    value = query,
                    onValueChange = {
                        onQueryChanged(it)
                    },
                    label = {
                        Text(text = "Search")
                    },
                    keyboardOptions = KeyboardOptions(
                        keyboardType = KeyboardType.Text,
                        imeAction = ImeAction.Done,
                    ),
                    leadingIcon = {
                        Icon(Icons.Filled.Search)

                        if (action == ImeAction.Done) {
                            onExecuteSearch()
                            softKeyboardController?.hideSoftwareKeyboard()
                        }
                    },
                    textStyle = TextStyle(color = MaterialTheme.colors.onSurface),
                    backgroundColor = MaterialTheme.colors.surface
                )


            }
            val scrollState = rememberScrollState()
            val scope = rememberCoroutineScope()
            Row(

                    .fillMaxWidth()
                    .padding(start = 8.dp, bottom = 8.dp)
                    .horizontalScroll(scrollState)
            ) {
                scope.launch {
                    scrollState.scrollTo(
                        scrollPosition
                    )
                }

                for (category in getAllFoodCategories()) {
                    FoodCategoryChip(
                        category = category.value,
                        isSelected = selectedCategory == category,
                        onSelectedCategoryChanged = {
                            onSelectedCategoryChanged(it)
                            onCategoryChangePosition(
                                getAllFoodCategories().indexOf(selectedCategory)
                            )
                        },
                        onExecuteSearch = {

                    )
                }
            }
        }
    }
}

You can only use the combination of parameters contained in only one of the implementations. You can't, for example, use keyboardOptions alongside onImeActionPerformed.

Turns out the backgroundColor property isnt valid anymore, use colors:. Also as pointed out by Richard Onslow Roper in his answer, look through the constructor of the TextField and see which properties are not part of your the Version of TextField you want to use

Don't do

          TextField(
                    value = query,
                    onValueChange = {
                        onQueryChanged(it)
                    },
                    label = {
                        Text(text = "Search")
                    },
                  
                    backgroundColor = MaterialTheme.colors.surface
                )

do this instead

          TextField(
                    value = query,
                    onValueChange = {
                        onQueryChanged(it)
                    },
                    label = {
                        Text(text = "Search")
                    },
                  
                    colors=  TextFieldDefaults.textFieldColors(
                        backgroundColor = MaterialTheme.colors.surface
                    )
                )
