Why does Android Studio dsplay Hint of MutableState<Sections> as Sections?-CodePudding

I use Android Studio Hint to display the type of a variable.

In Code A, the Hint of a is displayed as MutableState<Sections>, you can see Image A.

And the Hint of currentSection is displayed as Sections, you can see Image B, I think it should be MutableState<Sections>, right?

Code A

   val a = rememberSaveable { mutableStateOf(tabContent.first().section)}

   val (currentSection, updateSection) = rememberSaveable {       
        mutableStateOf(tabContent.first().section)
    }

Image A

Image B

CodePudding user response：

a and currentSection was expected to have different data type.

currentSection is assigned by using destructuring declaration

val (currentSection, updateSection) = rememberSaveable {
    ...
}

In jetpack compose, you can create state in multiple ways

val mutableState = remember { mutableStateOf(default) }
var value by remember { mutableStateOf(default) }
val (value, setValue) = remember { mutableStateOf(default) }
