NavigationContext

NavigationContext 提供 navigation 对象（与 navigation 属性相同的对象）。事实上，useNavigation 使用此上下文来获取 navigation 属性。

¥NavigationContext provides the navigation object (same object as the navigation prop). In fact, useNavigation uses this context to get the navigation prop.

大多数时候，你不会直接使用 NavigationContext，因为提供的 useNavigation 涵盖了大多数用例。但如果你有其他想法，NavigationContext 可供你使用。

¥Most of the time, you won't use NavigationContext directly, as the provided useNavigation covers most use cases. But just in case you have something else in mind, NavigationContext is available for you to use.

示例：

¥Example:

Static

import { NavigationContext } from '@react-navigation/native';

function SomeComponent() {
  // We can access navigation object via context
  const navigation = React.useContext(NavigationContext);

Dynamic

import { NavigationContext } from '@react-navigation/native';

function SomeComponent() {
  // We can access navigation object via context
  const navigation = React.useContext(NavigationContext);
