FieldArray gives my rendered component a prop called value, is this a public API?

[GavinThompson]

Are you submitting a bug report or a feature request?

Bug report, maybe? Docs?

What is the current behavior?

The component I pass to <FieldArray> in the component prop receives a prop called value. Is this a public/stable API?

I don't see this in FieldArrayRenderProps, either in the docs or the flow types.

What is the expected behavior?

Sandbox Link

Here's the FieldArray example, adapted to show I can read from the value prop.

What's your environment?

Same as the example codesandbox.

Other information

Ultimately what I'm looking for is a way to read from the FieldArray programmatically/imperatively.

In redux-form I could use .get() and/or .getAll(), but this isn't available in react-final-form.

Any guidance?

Wow. Brilliant observation! I totally overlooked that.

Let me think about it, but without thinking too much about it, I'm leaning towards the redux-form API...

Excellent, thanks for the quick response! Will hold off on any more changes on our end and circle back in the near future. Thanks again! 😄

@erikras It seems this been removed from the latest version, any plans for alternate api ?

It would be really nice to have the get functionality. As a work-around, I had success with the Field component; it works with both the entire FieldArray name as well as the field name from a call to fields.map():

<FieldArray name='myArray'>
  {({ fields }) => (
    <React.Fragment>
      {fields.map((name) => (
        <Field name={name} subscription={{value: true}}>
          {({ input: { value: field }}) => (
            <div>{JSON.stringify(field, null, 2)}</div>
          )}
        </Field>
      )}
      <Field name='myArray' subscription={{value: true}}>
        {({ input: { value: fieldValues }}) => (
          <div>{JSON.stringify(fieldValues, null, 2)}</div>
        )}
      </Field>
    </React.Fragment>
  )}
</FieldArray>

Published fix in v3.1.1.
