Can't add object to existing array (useState react native)

I have addText() that runs on click event

const [list, setList] = useState([])
const [value, setValue] = useState("")

useEffect(() => {
    getObjectItem("tasks")
        .then(t => setList(t.item))
        .catch(e => { console.log(e) })
}), []
// A function that add data to the list array

function addText(text) {
    console.log(list);
    if (value !== "") {
        setList(prev =>
            [...prev,
            { text: text, isSelected: false }] // Adding a JS Object

        )
        setObjectItem("tasks", list);
        setValue("")
    } else {
        alert("Please type in something!")
    }
}

Output from console.log(list):

  Array [
          Object {
            "isSelected": true,
            "text": "Test",
          }
        ]

getObjectItem("tasks") function:

const getObjectItem = async (name) => {
  try {
    const jsonItem = await AsyncStorage.getItem(name)
    const item = JSON.parse(jsonItem)
    return {
      status: 'success',
      name: name,
      item: item
    }
  } catch (err) {
    return {
      status: 'error',
      name: name,
      error: err
    }
  }
}

Why can’t I add values to the existing list array with setList() in addText() function?
