```
@Target(allowedTargets = {AnnotationTarget.FUNCTION}) 
public @interface NavHostDefaultStartArgs<T extends Annotation>

                    
```
Annotation used on a public top level function to make it be used as the start navigation arguments of a NavHostGraph. Useful when the start route of the NavHostGraph has mandatory arguments and you don't want to make them non mandatory (because maybe when you navigate to that destination, defaults make no sense, they only make sense when the app starts initially).
Example:
```
@NavHostDefaultStartArgs<RootGraph>
fun defaultRootGraphStartArgs() = MyStartDestinationArgs(
    //fill default arg values here
)
```
Note that RootGraph in the example is the NavHostGraph you want to use these on, and the MyStartDestinationArgs is the start route arguments class (which needs to match with the nav arguments class of the NavHost's start route).
