以antd-mobile为设计标准，基于taro框架的微信小程序组件库

import { __rest } from "tslib";
import React, { useLayoutEffect, useRef } from 'react';
import RcForm from 'rc-field-form';
import isEqual from 'lodash/isEqual';
import { FormContext } from './context';

const Form = props => {
  const {
    children
  } = props,
        formProps = __rest(props, ["children"]);

  const {
    initialValues,
    form
  } = props;
  const preValue = useRef();
  useLayoutEffect(() => {
    if (initialValues && !isEqual(initialValues, preValue.current) && form) {
      preValue.current = initialValues;
      form.setFieldsValue(initialValues);
    }
  }, [form, initialValues]);
  return React.createElement(RcForm, Object.assign({}, formProps), React.createElement(FormContext.Provider, {
    value: {
      value: initialValues
    }
  }, children));
};

export default Form;
