GenerateConfig is not undefined

Is there anyone find that, Generateconfig is passed in through props, but there is no API description. As a result, the value of generateconfig is undefined and an error will be reported when using it.

Use according to novice guidelines

`export default function IndexPage() {

return (

  <Picker />

);
}`

there will be a error,because Generateconfig is undefined
`TypeError: Cannot read property 'locale' of undefined
formatValue
./node_modules/rc-picker/es/utils/dateUtil.js:126
123 | var generateConfig = _ref.generateConfig,
124 | locale = _ref.locale,
125 | format = _ref.format;

126 | return typeof format === 'function' ? format(value) : generateConfig.locale.format(locale.locale, value, format);
127 | }
128 | export function parseValue(value, _ref2) {
129 | var generateConfig = _ref2.generateConfig,
View compiled`

Is that mean we should give Generateconfig a default value from generate

Start with the Picker usage example and the reported stack location, node_modules/rc-picker/es/utils/dateUtil.js, especially formatValue where generateConfig.locale is accessed. Trace how generateConfig reaches Picker and check the existing API guidance or tests. Done means the documented novice usage no longer produces the reported undefined-value error.
