Inconsistent TypeScript behavior with optional arguments in useNavigation

When using the useNavigation hook from @react-navigation/native in TypeScript, optional arguments are not being correctly inferred and produce a type error.
Expected Behavior:
Optional arguments should be correctly inferred and not produce a type error.
Actual Behavior:
Optional arguments produce a type error, requiring the use of the // @ts-ignore comment to suppress the error.
Steps to Reproduce:
- Use the useNavigation hook with an optional argument.
- Attempt to pass a string value as the optional argument.
- Observe the type error.
import { useNavigation } from '@react-navigation/native';
const navigation = useNavigation();
const navigate = (screenName?: string) => {
// Argument of type 'string' is not assignable to parameter of type 'never'
navigation.navigate(screenName)
// Workaround with // @ts-ignore
// @ts-ignore
navigation.navigate(screenName)
}
