Given your navigation graph, there is no way to associate fragmentA2 with your menu item fragmentA, so fragmentA is not selected when you return to fragmentA2. As per this issue:

NavigationUI has 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 R.id.frag_second.

So when you navigate() to R.id.frag_hint via your button in HomeFragment, NavigationUI receives a callback that the current destination has changed to R.id.frag_hint. It looks at that NavDestination and notes that there's no menu item that matches R.id.frag_hint. It then looks at the destination's parent graph - your R.id.sample element. There's no menu item that matches that ID either, so NavigationUI can'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 NavigationUI perspective 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_hint and any menu item, which means NavigationUI does nothing. If you want to link R.id.frag_hint to 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:

While my solution isn't exactly what you describe under Option 2, it is close. We use combineWidgets() to create a grid with a single column and a row height where one graph covers most of the screen height. We squeeze in a link between each widget instance that scrolls the browser window down to show the following graph when clicked.

Let me know if this is working for you. It should be possible to automatically adjust the row size according to the browser window size. Currently, this depends on the browser window height being around 1000px.

I modified your code for the graph creation slightly and wrapped it in a function. This allows us to create 25 different-looking graphs easily. This way testing the resulting HTML file is more fun! What follows the function definition is the code to create a list of HTML objects that we then feed into combineWidgets().

We have fixed the issue by replacing

You can add both NUnit Framework and NUnit Test Adapter using NuGet Packages.

To do that, right click on your project in Solution Explorer, go to Manage NuGet packages..., in the Browse section type nunit, install NUnit package and the corresponding version adapter (NUnitTestAdapter for NUnit 2.x or NUnit3TestAdapter for NUnit 3.x).

It is the expected behaviour. You are constructing two separate app bars for both the screens so they are bound to flash. This is not the correct way. The correct way would be to actually put the scaffold in your main activity and place the NavHost as it's content. If you wish to modify the app bar, create variables to hold state. Then modify them from the Composables. Ideally, store then in a viewmodel. That is how it is done in compose. Through variables.

You could have users select a file in the rendered document by embedding a Shiny application. The caveat is that all expressions involving dependencies of the user's selection have to be wrapped inside of reactive(). That is obviously not optimal if you are trying to teach R, but in case it helps or inspires a better answer, here is an example:

I think you cannot achieve this with BottomAppBar without working some hacks around it. I can suggest you use 2 FABs, an invisible one to get the BottomAppBar curved the way you wish, and another one (the actual one) and place it at the position you need it to be placed at, here is an example

I had the same problem. You should change the import of 'assets/.../variables.scss' to './assets/.../variables.scss'. In my case it was in styles.scss but it can be in every .scss file.

Generally, your setup looks fine. I would, however, suggest to do it as shown in Google's documentation: https://developers.google.com/analytics/devguides/collection/analyticsjs/enhanced-ecommerce
