I'm a novice developer. I have a project that requires a barcode scanner. which is developed with react native. I want to hide the keyboard. I can hide it but when I open the app and fold it and reopen it. My cursor is out of focus. And if I press any other area in the app, my cursor will not focus as well. I want to know why and solutions for this. Thank you for the advice :,

My app only works on android 7.

const dataInput = useRef(null)
const [data, setData] = useState('')

useEffect(() => {
    setData('')
    dataInput.current.focus()
  }, [isFoucs])


       <TextInput
          value={data}
          onChangeText={e => setData(e)}
          returnKeyType="go"
          ref={dataInput}
          onSubmitEditing={checkData}
          showSoftInputOnFocus={false}
        />
