If using the new style context, re-declare this in your class to be the
React.ContextType of your static contextType.
Should be used with type annotation or static contextType.
static contextType = MyContext
// For TS pre-3.7:
context!: React.ContextType<typeof MyContext>
// For TS 3.7 and above:
declare context: React.ContextType<typeof MyContext>
根据 name 订阅 FieldSet 的值
根据 name 或者 model 订阅字段校验状态的更新
当参数是 Model 对象时不依赖 FormContext，参数是字段名时必须在有 FormContext 的环境下使用。
根据 name 或者 model 订阅字段值的更新
创建一个 FieldArray builder
数组元素的 builder 对象，可以是 field、array 或者 set 的返回值
If set, this.context will be set at runtime to the current value of the given Context.
Usage:
type MyContext = number
const Ctx = React.createContext<MyContext>(0)
class Foo extends React.Component {
static contextType = Ctx
context!: React.ContextType<typeof Ctx>
render () {
return <>My context's value: {this.context}</>;
}
}
创建一个异步校验函数
异步校验函数的实现
创建一个 Field builder
Field 的默认值
创建一个 Form builder，是最顶层的 builder 对象
Form 每个字段对应的 builder 对象，其值可以是 field、array 或者 set 的返回值
判断一个校验函数是否是异步的，异步的校验函数必须使用 createAsyncValidator 创建
校验函数
创建一个 FieldSet builder
FieldSet 每个字段对应的 builder 对象，其值可以是 field、array 或者 set 的返回值
获取一个 Field。
Model 模式下传入字符串类型的 field 时， validators 和 defaultValue 均无效。
字段名
默认值
校验函数数组
获取一个 Field
Field 对应的 model 对象，用于关联 Field 和 model；当 FormStrategy 是 Model 或渲染 FieldArray 的时候才能使用

订阅 model 的校验状态
当参数是 Model 对象时不依赖 FormContext，参数是字段名时必须在有 FormContext 的环境下使用。
订阅 model 的值。

Subscribe value of form. Note that this hook might cause performance problem(s), use it with caution.
Return value of Form.useForm
Subscribe value of form. Note that this hook might cause performance problem(s), use it with caution.
Return value of Form.useForm
订阅 model 的校验状态
订阅 model 的值
订阅名为 name 的子 model 变更。
变更包括增加/删除该子 model，但不包括子 model 内部数据的变化。
订阅 child 的 FieldSetModel
child 的名字
Called immediately before mounting occurs, and before Component#render.
Avoid introducing any side-effects or subscriptions in this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.
Calling Component#setState generally does not trigger this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
Called immediately before rendering when new props or state is received. Not called for the initial render.
Note: You cannot call Component#setState here.

Catches exceptions generated in descendant components. Unhandled exceptions will cause the entire component tree to unmount.
Called immediately before mounting occurs, and before Component#render.

Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
Runs before React applies the result of render to the document, and
returns an object to be given to componentDidUpdate. Useful for saving
things such as scroll position before render causes changes to it.
Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated lifecycle events from running.
Called to determine whether the change in props and state should trigger a re-render.
Component always returns true.
PureComponent implements a shallow comparison on props and state and returns true if any
props or states have changed.
If false is returned, Component#render, componentWillUpdate
and componentDidUpdate will not be called.
