In step 5 HttpRepl emits the warning Unable to find an OpenAPI description, which means that it can't find the swagger endpoint, and therefore the ls command wont work.

I assume you are using VS Code and ASP.NET Core 5.0. Here is my output from running dotnet --version:

The problem is with Props which is a CompositeScreenProp and that is for the following use case:

when you nest navigators, the navigation prop of the screen is a combination of multiple navigation props. For example, if we have a tab inside a stack, the navigation prop will have both jumpTo (from the tab navigator) and push (from the stack navigator). To make it easier to combine types from multiple navigators, you can use the CompositeScreenProps type

It is explicitly used for typing the navigation prop. That is why the typing (including autocompletion) works for navigate. We can check how this works step by step. The navigate function receives the screen to which it should navigate.

This is typed using the CompositeScreenProp! By specifying the screen in the params prop, it can extract the type of the props from the CompositeScreenProps. We can test this as well by not specifying the screen.

Clearly, the Typescript compiler can not extract the type information here.

Hence, using the construction React.FC does not extract the type information for the BTwo props. This is a react-native construction. It has nothing to do with react-native-navigation.

It is specified in the react-native-navigation documentation on how to type the props of a screen in the Type checking screens​ section and this does not differ from typing a normal Javascript function using Typescript. A react-native functional component is, loosely speaking, a JS function that returns a JSX component. It is typed the usual way.

We have fixed the issue by replacing

File->Settings->Tools->Emulator, and uncheck Launch in a tool window Then they will open in their own stand alone windows again.

ServiceBusClientBuilderExtensions.AddServiceBusClient is an extension method of IAzureClientFactoryBuilder:

It looks like you have defined custom paths in your TypeScript config (usually tsconfig.json). The import plugin doesn't know about the correct location of the TypeScript config and hence cannot resolve those paths. What you need to do, is to specify the correct path to your TypeScript config via the project parameter in the resolver options:

Remember that each of the on variables is a callback. onScreenChange implicitly passes the variable it as String, but it is not necessary to use the variable within your callback.

1. it is implicitly passed, but in the GitHub link you gave, the programmer decided to rename it to onScreenChange. That callback then was passed to OverviewBody, which overrides the default {}, as you said. What I don't understand about your question is where onAccountClick is coming from. That is not a parameter of OverviewBody, according to the GitHub code.

2. content has a parameter for another callback, which you noticed. The body variable for each class in the enum is then invoked, and the callback parameter is passed to the invocation. In the future, that callback will only be used by OverviewBody. Remember that body(callback) is the same as body.invoke(callback).

I hope this helps. Please let me know if anything needs some more explanation.

Additional Content Edit:

1. I see the parameters in your code, not the one on GitHub. My apologies for missing that.
2. body is a variable function. This means that the variable function can be invoked, either by writing body(...) or body.invoke(...). The String parameter it, which is passed implicitly, is ignored and the default values are used, unless specified like you suggested (onAccountClick=it).

I think that you need to wrap your component withNavigation HOC https://reactnavigation.org/docs/4.x/with-navigation/

That's because your component not directly from the component Navigator, so they don't have this.props.navigation, to make your component have navigation props in Class Component, you need to wrap your component using withNavigation HOC

example:

You can pass a parameter from Screen3 to the Home screen.

I have forked your demo and did some small refactoring (including changing from Class to Function components just for preference) so you may need to adapt it to your needs. You can find it here.

In Screen3 you can modify your onPress logic to the following:
