A modern programming language that makes developers happier.

I’m trying to understand this:

<https://google.github.io/accompanist/pager/#reacting-to-page-changes>

&gt; The `PagerState.currentPage` property is updated whenever the selected page changes. You can use the `snapshowFlow` function to observe changes in a flow:
```LaunchedEffect(pagerState) {
    snapshotFlow { pagerState.currentPage }.collect { page -&gt;
        // Selected page has changed...
    }
}```
Why can’t I just access the current page via `pagerState.currentPage`? Why do I have to wrap it in a `LaunchedEffect` and `snapshotFlow`?

In an example about <https://google.github.io/accompanist/pager/#integration-with-tabs|integrating tabs> with this, they directly access `PagerState.currentTab`

Reading the value in composition is fine. That example is showing you how to turn page changes into an event stream, for things like analytics
