I am working on Frontends using Kotlin and Jetpack compose in Android Studio.
I have created a Kotlin-File that contains a composable function and no attributes.
I was thinking of a class diagram, but the file has no attributes, only a function.
How can I draw a diagram that represents this file and its composable function?
Which diagram should I choose?

What is the proper way to store tab content state in Compose Multiplatform? "Remember" keeps state only during recompositions, not when one view replaces another. On Android ViewModel should be used, but in Compose Multiplatform there is no ViewModel class.
I want to take screenshot of specific composable function on Jetpack Compose. How can I do this? Please, anyone help me
There is currently no support for this. Compose applications have only one view (window.decorView). You can use traditional methods to get a screenshot of the root view but that is for the entire screen. If you know the location of the composable compoenent on the screen that you want the screenshot of, you will have to apply clipping to the bitmap that you get from the whole screen.
What is the best way to get the functionality of a CoordinatorLayout in Jetpack Compose?
I know that a Box is essentially a FrameLayout and CoordinatorLayout is a super-powered FrameLayout but is there a super-powered Box layout?
I guess we need to use nestedScroll modifier.
There is a Collapsing Toolbar Example on documentation page.
I am writing a custom component for a Windows 8.1 tablet application our team are mostly developing in React Native.
I've realised that some of the custom code we need doesn't naturally belong to any specific UI element. For example, we want a button to trigger the native Camera UI dialog (as in this CameraUICapture element sample). However, there's no reason this would necessarily be triggered from a button. It could be a callback from something else, it could be a click event on an image. I don't want to lock the function calls to a specific UI piece.
All the tutorials and demos I have managed to find so far for React Custom Components are explicitly for UI pieces, and require implementing a React View manager subclass to interact with React when the piece is loaded. Is this the only way to write native code accessible from a React page? Do I need at least a dummy UI element even to hook into functional code in the native layer, or is there another way?
It turns out the phrase I'm yearning for is "Native Modules".

Is it possible to use React Native only for one view within the project?
I've successfully added React view for particular iOS app screen (using instructions from "Integration with existing iOS project" docs), but i don't know how to get data from that screen and call other (objective-c) code. For example I want to replace old storyboard-based Search Form to React view and then call storyboard-based screens when user clicks "Search".
Or it is intended to make all views in React and convert existing non-React views into 'native' components (very huge work for big apps)?
This is easily accomplished via the Native Module concept which is described here - https://facebook.github.io/react-native/docs/nativemodulesios.html
You can export obj-c methods to JS via a single call.
I've solved my issue in following way:
Create Native Module wrapper around NSNotificationCenter, so
javascript code could publish iOS events.
Subscribe for that event within ReactController-wrapper around React-Native code.
Raise event when user clicked «Search» (when we need to give control back to objective-c) with needed data to pass as dictionary.
Catch event, process data, open other controllers/etc
