 Used when there are dependencies between fields. If a field has the `dependencies` prop, this field will automatically trigger updates and validations when upstream is updated. A common scenario is a user registration form with "password" and "confirm password" fields. The "Confirm Password" validation depends on the "Password" field. After setting `dependencies`, the "Password" field update will re-trigger the validation of "Check Password". You can refer [examples](#components-form-demo-register).
 
+`dependencies` shouldn't be used together with `shouldUpdate`. Since it may cause chaos in updating logic.
+
+`dependencies` supports `Form.Item` with render props children since `4.5.0`.
+
 ### shouldUpdate
 
 Form updates only the modified field-related components for performance optimization purposes by incremental update. In most cases, you only need to write code or do validation with the [`dependencies`](#dependencies) property. In some specific cases, such as when a new field option appears with a filed value changed, or you just want to keep some area updating by form update, you can modify the update logic of Form.Item via the `shouldUpdate`.

 当字段间存在依赖关系时使用。如果一个字段设置了 `dependencies` 属性。那么它所依赖的字段更新时，该字段将自动触发更新与校验。一种常见的场景，就是注册用户表单的“密码”与“确认密码”字段。“确认密码”校验依赖于“密码”字段，设置 `dependencies` 后，“密码”字段更新会重新触发“校验密码”的校验逻辑。你可以参考[具体例子](#components-form-demo-register)。

 Form 通过增量更新方式，只更新被修改的字段相关组件以达到性能优化目的。大部分场景下，你只需要编写代码或者与 [`dependencies`](#dependencies) 属性配合校验即可。而在某些特定场景，例如修改某个字段值后出现新的字段选项、或者纯粹希望表单任意变化都对某一个区域进行渲染。你可以通过 `shouldUpdate` 修改 Form.Item 的更新逻辑。

+## FAQ
+
+### Why I can not access context, redux in message?
+
+antd will dynamic create React instance by `ReactDOM.render` when call message methods. Whose context is different with origin code located context.
+
+When you need context info (like ConfigProvider context), you can use `message.useMessage` to get `api` instance and `contextHolder` node. And put it in your children:
+
+```tsx
+const [api, contextHolder] = message.useMessage();
+
+return (
+  <Context1.Provider value="Ant">
+    {/* contextHolder is inside Context1 which means api will get value of Context1 */}
+    {contextHolder}
+    <Context2.Provider value="Design">
+      {/* contextHolder is outside Context2 which means api will **not** get value of Context2 */}
+    </Context2.Provider>
+  </Context1.Provider>
+);
+```
+
+**Note:** You must insert `contextHolder` into your children with hooks. You can use origin method if you do not need context connection.

+## FAQ
+
+### 为什么 message 不能获取 context、redux 的内容？
+
+直接调用 message 方法，antd 会通过 `ReactDOM.render` 动态创建新的 React 实体。其 context 与当前代码所在 context 并不相同，因而无法获取 context 信息。
+
+当你需要 context 信息（例如 ConfigProvider 配置的内容）时，可以通过 `message.useMessage` 方法会返回 `api` 实体以及 `contextHolder` 节点。将其插入到你需要获取 context 位置即可：
+
+```tsx
+const [api, contextHolder] = message.useMessage();
+
+return (
+  <Context1.Provider value="Ant">
+    {/* contextHolder 在 Context1 内，它可以获得 Context1 的 context */}
+    {contextHolder}
+    <Context2.Provider value="Design">
+      {/* contextHolder 在 Context2 外，因而不会获得 Context2 的 context */}
+    </Context2.Provider>
+  </Context1.Provider>
+);
+```
+
+**异同：**通过 hooks 创建的 `contextHolder` 必须插入到子元素节点中才会生效，当你不需要上下文信息时请直接调用。

+### message/notification/Modal.confirm lost styles when set `prefixCls` on ConfigProvider?
+
+Static methods like message/notification/Modal.confirm are not using the same render tree as `<Button />`, but rendered to indepent DOM node created by `ReactDOM.render`, which cannot access React context from ConfigProvider. Consider two solutions here:
+
+1. Replace original usages with [message.useMessage](https://ant.design/components/message/#components-message-demo-hooks), [notification.useNotification](https://ant.design/components/notification/#Why-I-can-not-access-context,-redux-in-notification) and [Modal.useModal](https://ant.design/components/modal/#Why-I-can-not-access-context,-redux-in-Modal.xxx).
+
+2. Use `message.config`, `notification.config` and `Modal.config` to config `prefixCls` globally.
+
+```js
+message.config({
+  prefixCls: 'ant-message',
+});
+notification.config({
+  prefixCls: 'ant-notification',
+});
+Modal.config({
+  rootPrefixCls: 'ant',
+});
+```

+### ConfigProvider 设置 `prefixCls` 后，message/notification/Modal.confirm 生成的节点样式丢失了？
+
+message/notification/Modal.confirm 等静态方法不同于 `<Button />` 的渲染方式，是单独渲染在 `ReactDOM.render` 生成的 DOM 树节点上，无法共享 ConfigProvider 提供的 context 信息。你有两种解决方式：
+
+1. 使用官方提供的 [message.useMessage](<[message.useMessage](https://ant.design/components/message-cn/#components-message-demo-hooks)>)、[notification.useNotification](https://ant.design/components/notification-cn/#%E4%B8%BA%E4%BB%80%E4%B9%88-notification-%E4%B8%8D%E8%83%BD%E8%8E%B7%E5%8F%96-context%E3%80%81redux-%E7%9A%84%E5%86%85%E5%AE%B9%EF%BC%9F) 和 [Modal.useModal](https://ant.design/components/modal-cn/#%E4%B8%BA%E4%BB%80%E4%B9%88-Modal-%E6%96%B9%E6%B3%95%E4%B8%8D%E8%83%BD%E8%8E%B7%E5%8F%96-context%E3%80%81redux-%E7%9A%84%E5%86%85%E5%AE%B9%EF%BC%9F) 来调用这些方法。
+
+2. 使用 `message.config`、`notification.config` 和 `Modal.config` 方法全局设置 `prefixCls`。
+
+```js
+message.config({
+  prefixCls: 'ant-message',
+});
+notification.config({
+  prefixCls: 'ant-notification',
+});
+Modal.config({
+  rootPrefixCls: 'ant', // 因为 Modal.confirm 里有 button，所以 `prefixCls: 'ant-modal'` 不够用。
+});
+```
+
 ### 如何正确的拼写 Ant Design？
 
 - ✅ **Ant Design**：用空格分隔的首字母大写单词，指代设计语言。
