asyncValidate doesn't get the value from blurred field on React Native

[JoaoMosmann]

Subject of the issue

asyncValidate doesn't get the value from blurred field on React Native.

Your environment

Software	Version(s)
redux-form	^8.3.7
redux	^4.0.4
react-redux	^7.2.1
react	16.9.0
react-native	0.61.2
node	12.13.0
yarn if using	1.22.10
Browser	native
Operating System	android

Steps to reproduce

On a react-native environment
Create a form with a TextField.
On reduxForm() setup like:

reduxForm({
  name: 'formName',
  asyncBlurFields: ['fieldName'],
  asyncValidate: async (values, dispatch, props) => {
    console.log({ values });
    // fieldName will be undefined 
  }
})

Expected behaviour

On blurring a TextField, the asyncValidate function should be called with the field value

Actual behaviour

On blurring the field, the asyncValidate function will be triggered, but the value will be undefined

Other information

The root of the cause seems to be on the file ConnectedField.js line 176. The onChangeValue returns undefined as the getValue tries to read the variable event.nativeEvent.text which does not exist on the blur event.

The same when using Parser.

Facing same issue with below are package version
"react": "16.11.0",
"react-native": "0.62.2",
"react-redux": "7.2.0",
"redux": "^4.0.5",
"redux-form": "8.3.6"

Observation 1 : the fields which are passing in asyncBlurFields, have undefined value, getting rest all values of form,
if using asyncChangeFields instead of asyncBlurFields I am getting values as expected on change, but I need all form values on blur.

Observation 2 : if there is multiple filedName passed in asyncBlurFields, for current active filed is empty but getting rest form values.
