You could use the group attribute in the Preview.
Something like:

fun test1(){ }
Then in the Preview panel you can select the preview group:
In this way you can select the preview to be displayed.

Android Jetpack Compose text that starts next to the image and continues below it

How can I make a design like the image with Jetpack Compose? I searched a lot, but I couldn't get any answer similar to the structure I wanted.

You can try out Romain's newest library
Composable widget for Jetpack Compose that allows to flow text around arbitrary shapes over multiple columns.
to achieve this and much more: https://github.com/romainguy/combo-breaker

How about using a simple Text only, but inside a Box where we can clip the size of the image using modifier!!
Box {
Image(modifier = modifier.clicp(RoundedCornerShape(...)))
Text(...)
}
modifier.clip(...) is something which can do the trick.

You can add Images inside text using AnnotatedString and inLineContent parameter of Text Composable
like How adding ImageSpan in jetpack compose Text
or you can use Box Composable and Clip your image using Modifier.clip(Shape)

Visualizing Component Tree in Jetpack Compose

In Android View System you can see the UI tree of different elements that make up the view hierachy for example as shown below:
Apart from Previewing the Composables, I am looking for a way to visualize the Composables in a Component Tree for example given this code:
#Composable
fun TodoScreen(....) {
Column(){
LazyColumn{
...}
Row{
Button(){....}
Text(){...}
}
}
}
Please let me know if there is a way to display a Component Tree on Android Studio Arctic Fox similar to the above Android View Hierachy Image.

You can use View -> Tool Windows -> Layout Inspector

Shared element transition in Jetpack compose

I wanted to animate my image logo from Screen A to Screen B. In XML based layouts it was possible using windowContentTransitions & transitionName. So I wanted to ask is something similar available in Jetpack Compose?
I have already seen this https://github.com/mobnetic/compose-shared-element
But, Is there something in-built functionality similar to the XML?

Not supported yet by compose. See this conversation on kotlin-lang: https://kotlinlang.slack.com/archives/CJLTWPH7S/p1616517641495500?thread_ts=1616516302.494300&cid=CJLTWPH7S

I'm new to Jetpack Compose. I created an app and as a preview I get only the views, in my case a text view.
How can I preview a screen and not an individual element?
I want something like that:

How to display layout in Jetpack Navigation when using Compose?

I started using Jetpack Compose and I'm very happy with it. I replaced a couple of layouts that where defined in xml by a #Composable function.
When I went back to my Navigation-xml I noticed that the preview inside every screen is done with tools:layout property. And property reference to a layout in xml. Not to an #Composable function.
Is there already a way to reference to a #Composable function from tools:layout in a Navigation xml so that the preview of my entire flow will be visible?
