Why Picker.prompt can't setting value?

Why Picker.prompt can't setting value?

I used prompt because I didn't want to define the components every time.

However, if I use prompt, the value cannot be set, so it is initialized every time.

Is there any other way?

prompt: (props: Omit<PickerProps, 'value' | 'visible' | 'children'>) => Promise<PickerValue[] | null>

<DemoBlock title='指令式调用'>
    <Button
      onClick={async () => {
        const value = await Picker.prompt({
          columns: basicColumns,
          value: [1] // <---------------------- 
        })
        Toast.show(`${value}`)
      }}
    >
      弹出 Picker
    </Button>
  </DemoBlock>

Can you write a simple demo oncodesandbox? It'll help us to check the problem.

@awmleer You can check the code here!

When I changed the status to "Bar" I hope status will be reflected in Picker.

I think this works

        const [pickerState, setPickerState] = useState([]);

        onClick={async () => {
          await Picker.prompt({
            columns: [
              [
                { label: "Foo", value: "foo" },
                { label: "Bar", value: "bar" }
              ]
            ],
            onConfirm: (value) => setPickerState(value),
            value: pickerState
          });
        }}

I fork your codesandbox and make changes

// line: 5
const [pickerState, setPickerState] = useState([]);
// line: 21
value: pickerState

Thank you for your answer. But it didn't work out.
I don't know why this isn't provided.
What I want is to keep the value of Picker, but when I call the prompt of Picker, Picker points to the first value every time.

And I don't think I can put the value in the props of the prompt.

I think it's possible that the codesandbox URL you visited is not mine.
try check this?

And I recorded a video below.
