Why pass route? Because it contains the state property which refers to the child's navigator state and the value of the currently active route name can be obtained from this state.Īdd a function called getHeaderTitle in AppNavigator.js file.In the React Native ecosystem, one can find many libraries aiming for an app navigation system working seamlessly both on iOS and Android. This can be done by defining a helper function called getHeaderTitle that has route as its parameter.

The tab navigator is nested inside the Stack navigator and thus, Profile is not the immediate child to Stack Navigator.įor each tab to have its own title (since the tab navigator is nested inside the stack navigator), you have to determine the title for a specific tab screen based on the navigation state from the property route.state. This is because the Profile screen is a child of the Tab Navigator and not Stack Navigator.

In the current scenario, if you are to set the title for the Profile screen passing the prop options, it is not going to work. This is because the root navigator (which, here is the Stack Navigator) structure is going to look at its immediate children, which are Home, Detail and Settings screen. Right now the title for each tab screen is going to be the same.
