描述
Current Behavior
- What code are you running and what is happening?
- Include a screenshot or video if it makes sense.
I'm trying to setup typescript for navigating into a nested navigator. From reading the doc, this was my attempt (which I'm assuming is wrong. It gives me''Create Conversation modal'' is referenced directly or indirectly in its own type annotation.ts(2502.
export type RootStackParamList = {
Home: undefined;
SignInUpTunnel: undefined;
'Create Conversation modal': NavigatorScreenParams<EditConversationModalNavigatorParamList>; <==== typescript error here
};
...
return
<AuthenticatedUserProvider>
<Stack.Navigator screenOptions={{ headerShown: false }} mode="modal">
<Stack.Screen name="Home" component={HomeDrawerNavigator} />
<Stack.Screen name="Create Conversation modal" component={EditConversationModalNavigator} />
</Stack.Navigator>
</AuthenticatedUserProvider>
...
export type EditConversationModalNavigatorParamList = RootStackParamList & {
'Create conversation': { userToInvite: UserConversationStatusCellData | null };
};
...
navigation.navigate('Create Conversation modal', { screen: 'Create conversation', params: { userToInvite } });
Unfortunately, the documentation on this topic is very thin: https://reactnavigation.org/docs/typescript#type-checking-screens-and-params-in-nested-navigator.
Also, the documentation uses a different navigation structure than the documentation for nesting navigators. making it hard to know where to actually put the NavigatorScreenParams and what paramList to give it.
Expected Behavior
I would expect the documentation for the typescripting of a nested navigator to include a full example (with the root navigator and nested navigator) and I would expect it to use the same navigators as the documentation to nest navigator.
How to reproduce
- You must provide a way to reproduce the problem. If you are having an issue with your machine or build tools, the issue belongs on another repository as that is outside of the scope of React Navigation.
- Either re-create the bug on Snack or link to a GitHub repository with code that reproduces the bug.
- Explain how to run the example app and any steps that we need to take to reproduce the issue from the example app.
- Keep the repro code as simple as possible, with the minimum amount of code required to repro the issue.
- Before reporting an issue, make sure you are on the latest version of the package.

调研方向
从 TypeScript 嵌套导航页面和 issue 中链接的单独 navigator 嵌套文档开始。比较它们的 navigator 结构,并使用所报告的 RootStackParamList 和 EditConversationModalNavigatorParamList 作为示例上下文。完成的标准是 TypeScript 页面包含一个完整且匹配的 root navigator 和 nested navigator 示例,并解释 NavigatorScreenParams 应放在哪里。
