BottomNavigationView with Navigation Component. When showing fragment is not root fragment, the tab icon is not updated (selected).
When I switch between Tab Home with Fragment A (which is root fragment) and Tab Star with Fragment B (which is also root fragment) it is working fine.
But when I navigate from Tab Home to another fragment, like fragment A2, and tap on Tab Star and again return to Tab Home, still Tab Star is selected in
It was working fine with version
2.4.0-alpha05, This is happening when I updated it to

Given your navigation graph, there is no way to associate
fragmentA2 with your menu item
fragmentA is not selected when you return to
fragmentA2. As per this issue:
NavigationUIhas always used the current destination and what graph it is part of as the source of truth for what tab should be selected.
This can be seen by calling
navigate()to go to your
SecondFragment- even though you haven't used the bottom nav button, the selected tab was changed because the current destination has changed to
So when you
R.id.frag_hintvia your button in
NavigationUIreceives a callback that the current destination has changed to
R.id.frag_hint. It looks at that
NavDestinationand notes that there's no menu item that matches
R.id.frag_hint. It then looks at the destination's parent graph - your
element. There's no menu item that matches that ID either, so
NavigationUIcan't associated that destination with any menu item and therefore simply does nothing. That is true on all versions of Navigation.
So what is different when you tap on a bottom navigation item? Well, nothing different from a
NavigationUIperspective in fact: the exact same code runs and the current destination and what graph it is part of is the source of truth for what tab should be selected. In the Navigation 2.3.5, there was no state saved for each tab, so it only 'worked' because selecting a tab forced the ID of the current destination to match the destination of the menu item you just tapped.
So what you're seeing in your sample app is that there's no link between
R.id.frag_hintand any menu item, which means
NavigationUIdoes nothing. If you want to link
R.id.frag_hintto your Home tab, then that's exactly what a nested navigation graph can be used for.
I.e., your navigation graph should instead look like:

You can pass the
navigationContainerRef from the
NavigationContainer to the
Navigation comomponent to make the
navigation object accessible.
Consider the following code snippet.

Where I add HomeF in main container which includes all bottom nav tab, and all bottom nav tab will open in home container, and those fragment which are not part of bottom nav will open in main container. I generally add(not replace) all the fragments in main container and set add to back stack , so that if user goes from profile (home_container) to something in main container , while backstack we can pop the top fragment and user will be seeing profile.

You can pass your
NavController to your
TopAppBar and use
navController.navigateUp() in the navigation icon.
If you want to show this icon only in some composables you can use a parameter, like
canPop in the following example, and set it true in the composable where you want handle the back button.
I have picker in my left menu navigation shell that change the main page language,

ANSWERAnswered 2022-Jan-26 at 06:20
The navigation stack of Shell has something special. Clear the navigation stack is not a good choice. We always use Routes to do the navigation for the Shell. You need to know which would generate the stack.
- A route, which defines the path to content that exists as part of the Shell visual hierarchy.
- A page. Pages that don't exist in the Shell visual hierarchy can be pushed onto the navigation stack from anywhere within a Shell application. For example, a details page won't be defined in the Shell visual hierarchy, but can be pushed onto the navigation stack as required.
For more details, please check the MS docs. https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/shell/navigation
When you press the back button, override the back button event and then judge the route to do the navigation would be better. Use the specific route name to go back.
After compilation the Navigation Bar that we call in Xamarin Forms, turns into the Action Bar for Android during runtime.
Set the toolbar after LoadApplication(new App()); in OnCreate of MainActivity.
I have a screen that makes a call to an api to fetch some data which is then displayed
An issue that I am seeing is that when I navigate away from the screen (I am using react-navigation 6.x) and then go back to it
useEffect() is not being called
From what I have read so far, this is down to the value of
userId not changing (I think i need to do some more reading around the
useEffect() hook to understand better, maybe someone will help clear things up with this question)

At the core, React Navigation does not rerender the screen when a user navigates back to that screen for performance optimization and avoids unnecessary rerenders.
When required, They provide a useful hook to detect when screen is focused and run some side effects.
Let refactor code as below:
I have a problem when do a call to my composable in the
NavGraph, it is repeating 3 times or sometimes more times. I have looked where I do the call and I don't see any loop or something.
ANSWERAnswered 2022-Jan-07 at 02:45
Navigation always crossfades destinations, so each screen will always recompose multiple times. This is expected as per the Thinking in Compose guide:
In some cases, a composable function might run for every frame of a UI animation. If the function performs expensive operations, like reading from device storage, the function can cause UI jank.
You aren't doing anything wrong (you aren't triggering side effects as part of composition), so your code is already fine.
