我开发了一个带有尾随图标的 textInput 可组合项，我想在单击该图标时清除 textInput。如何访问 textInput 值，以便清除它？

    @Composable
fun TextInput(
    myVal: String,
    label: String,
    placeholder: String="",
    helperText: String="",
    errorText: String="",
    onValueChange : (String) -> Unit){
    val hasError = !errorText.isNullOrEmpty()
    val helperColor =  if (hasError)
        Color(0xFFfe392f)
        else
            Color(0xFF5c6a79)

    Row() {
            Column() {
                TextField(
                    colors = TextFieldDefaults.textFieldColors(
                        backgroundColor = Color.Transparent,
                        textColor = Color(0xFF011e41),
                        cursorColor = Color(0xFF011e41),
                        focusedLabelColor = Color(0xFF011e41),
                        unfocusedLabelColor = Color(0xFF011e41),
                        unfocusedIndicatorColor = Color(0xFFebeced),
                        focusedIndicatorColor = Color(0xFF011e41),
                        errorCursorColor = Color(0xFFfe392f),
                        errorIndicatorColor = Color(0xFFfe392f),
                        errorLabelColor = Color(0xFFfe392f)
                    ),
                    value = myVal,
                    onValueChange = …

我想隐藏状态栏，并且我已经成功地使用伴奏库做到了这一点：

val systemUiController = rememberSystemUiController()
systemUiController.isStatusBarVisible = false

问题是，当应用程序进入后台并进入前台时，这段代码不会运行，因此状态栏会再次显示。我该如何解决这个问题？

谢谢。
