Dynamically Change React Navigation Value – Update navigationOptions
But wondering how would it work technically. What would do under the hood? Call a method on context which updates the navigator's state like I was thinking with navigation. Double rendering will still be an issue with this, no? I was thinking if suspense will be useful with this where we could pause rendering new content until the options are set. But since I haven't used suspense yet, I don't have much idea of how feasible it will be.

The screen would render afterward, provide options to useProvidedNavigationOptionsresolving the suspense promise with the new options. This doesn't actually sound that hard to implement, if you useNavigation inside of these new hooks in order to know the current navigation state from the navigator, and to know the current route key from the screen.
Also, a context-based API would be super valuable to help deep children get a reference back up to the Navigator they're contained in. It would be neat if Target were capable of dynamically putting something in the top-right navigation bar position on the Stackor dynamically telling the BottomTab to hide the tab bar.
Exposing a third parameter on the useNavigationOptions tuple could give helpers to get up the tree. Ideally then, we'd be able to dynamically show-hide the bottom-tab-bar, no matter how nested our subscreen is.How to turn on coordinates in minecraft bedrock realms

Contributor Author.You will see how to change the Navigation Option values dynamically from the click of a button or using a state. This can be easily done by setting the navigation params. This example will be helpful if you want to change the navigation options like navigation text, navigation text color, background color, etc on a click of a button or on some certain condition.
For example, if you are planning to make an application in which the user can change the theme of the application then here is an example for you to Dynamically Change React Navigation Value.
In this example, we will use react-navigation to make the navigation bar on the top of the screen and then with the help of three different buttons we will change the color of the navigation bar. Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App.
Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run.
If you want to start a new project with a specific React Native version, you can use the --version argument:. To switch between the screens and to make a default navigation header you need to install react-navigation and react-native-gesture-handler dependencies.
After the updation of React Native 0. So to install pods use.

Android IOS.Each screen component in your app is provided with the navigation prop automatically. The prop contains various convenience functions that dispatch navigation actions on the route's router. It looks like this:. It's important to highlight the navigation prop is not passed in to all components; only screen components receive this prop automatically!
React Navigation doesn't do any magic here. For example, if you were to define a MyBackButton component and render it as a child of a screen component, you would not be able to access the navigation prop on it.
If, however, you wish to access the navigation prop in any of your components, you may use the useNavigation hook. There are several additional functions present on navigation prop based on the kind of the current navigator. If the navigator is a stack navigator, several alternatives to navigate and goBack are provided and you can use whichever you prefer. The functions are:. You can find more details about navigator dependent functions in the documentation for the navigator that you're using.
The vast majority of your interactions with the navigation prop will involve navigategoBackand setParams. The navigate method lets us navigate to another screen in your app. It takes the following arguments:. Then you can use navigate :. Alternatively, as screen A is the top of the stack, you can use navigation. Note: Consider the navigator's state object to be internal and subject to change in a minor release.
Avoid using properties from the navigation state object except index and routesunless you really need it. If there is some functionality you cannot achieve without relying on the structure of the state object, please open an issue. The setParams method lets us update the params route. The setOptions method lets us set screen options from within the component. This is useful if we need to use the component's props, state or context to configure our screen.
Any options specified here are shallow merged with the options specified when defining the screen. Screens can add listeners on the navigation prop with the addListener method. For example, to listen to the focus event:. See Navigation events for more details on the available events and the API usage.
This method lets us check whether the screen is currently focused. Returns true if the screen is focused and false otherwise. This method doesn't re-render the screen when the value changes and mainly useful in callbacks.
You probably want to use useIsFocused instead of using this directly, it will return a boolean a prop to indicating if the screen is focused. The dispatch function is much less commonly used, but a good escape hatch if you can't do what you need with the available methods such as navigategoBack etc. We recommend to avoid using the dispatch method often unless absolutely necessary.A material-design themed tab bar on the bottom of the screen that lets you switch between different routes.
Routes are lazily initialized -- their screen components are not mounted until they are first focused. This API also requires that you install react-native-vector-icons!
If you are using Expo, it will just work out of the box. Otherwise, follow these installation instructions. This library uses the BottomNavigation component from react-native-paper. It doesn't include the whole react-native-paper library in your bundle, so you don't need to worry about it. Generic title that can be used as a fallback for headerTitle and tabBarLabel.

This is only supported when shifting is true. Title string of a tab displayed in the tab bar. When undefined, scene title is used. To hide, see labeled option in the previous section. Accessibility label for the tab button.
This is read by the screen reader when the user taps the tab. It's recommended to set this if you don't have a label for the tab. Useful for adding a custom logic before the transition to the next scene the tapped one starts.

Contributions welcome! If you use react-navigation v5, you should import hooks from react-navigation v5 directly, and should not add this project.
This is the main convenience hook. It provides the regular navigation prop, as you'd get via the screen prop or by using withNavigation. Access the navigation state of the current route, or if you're in a navigator view, access the navigation state of your sub-tree. Permit to execute an effect when the screen takes focus, and cleanup the effect when the screen loses focus. NOTE : To avoid the running the effect too often, it's important to wrap the callback in useCallback before passing it to useFocusEffect as shown in the example.
