observer | Observability For Go Applications | Monitoring library

I am building an application where one of the pages has a webview. Currently the page has a the webview representable and a view. Webview is brought to the view using the UIViewControllerRepresentable. I am wondering firstly how when I tap the login button can I call a function inside the LoginWebview, and also secondly vice versa, how can I call a function in the LoginView from the LoginWebview. I currently have the set up so that when I click login it toggles the states which causes the updateUIView to trigger but how can I call a custom made function in there? And vice versa

Apologies for the long description above and if this a stupid question

Thanks :)

LoginView:

I get this most common error message in shiny app. I am well aware of this error and have resolved it dozens of time. But this time I am stumped.

I'm diving into Kotlin Flow for the first time, and I'm wondering if with it ViewModel has a place anymore. ViewModel's advantage was that it was lifecycle aware and would automatically cancel subscriptions on the ViewModel's LiveData when the Activity gets destroyed. A Kotlin SharedFlow works similarly to LiveData in that it can be subscribed to by multiple observers. And in Kotlin a lifecycleScope coroutine should cancel all child coroutines upon the lifecycle ending. So if we had something like this:

I am new into RxJava and I was under the impression that for each event each subscriber is being notified. So if we have N subscribers and a stream of X events the onNext for each of the N subscribers would be called. But when I run the following code:

I am trying to change background video on scroll, using react-intersection-observer. When inView changes to true, useEffect must change state to sample2, and send new video to startscreen, where it's using as background video with position fixed. State is changing, but video is still the same.

//Startscreen

I've been testing out the Intersection Observer API specifically, in React. I'm running into an issue where, when I set the options argument's root property, the observer cannot properly identify when elements are visible. If that wasn't entirely clear, please see my code below:

As the title says, I'm trying to use swiperjs with Vue 2. I've used the API from swiper and another library "vue-awesome-swiper" to try and get it working. I get to the point with both approaches where everything appears functional but it's just the navigation buttons that aren't working and touch swiping is also disfuncitonal.

In each of the following approaches, I'm getting a seemingly perfect swiper but navigation is not working in either. I'm using vue 2.6 and swiper 6.7.

Here's what I have using vue-awesome-swiper:

I coded lazy loading for videos, background images and images but didn't work on ios safari.

I want show the background images/images/video with IntersectionObserver method.

below codes are for background image and video.

I want to observe two behaviorRelays with a single observer, wait for both relays to emitt their values, then in the subscription have two seperate closure arguemts, one for each relay. Something like this:
