Compose Jetpack — Side Ratio
The facet ratio has a reference primarily based on the unique dimensions: width, top, min, max. Overload the Side Ratio Modifier.
If you’re an Android, desktop, net or iOS developer working with Jetpack Compose for UI design, figuring out how one can resize your views is important to assist freeform window or any type issue.
On this article, we’ll discover how one can obtain the specified visible impact utilizing Jetpack Compose
Modifier overload of the facet ratio. The objective can be to make use of the guardian’s measurement as a reference for resizing the Combinable operate.
The answer is obtainable on GitHub and JitPack.
In order for you the sq. view to dynamically measurement primarily based on the unique measurement, set
aspectRatio with a worth of
If you wish to present thumbnails of YouTube movies, set
ratio = 16f / 9f.
What’s nice about

Constraints.findSize(). That is the place the logic of “resize” is available in.
That is the tactic we would like:
And right here, the complete implementation of the answer:
To verify the code is working, the Android Studio preview is nice.
Right here, the code to get the preview later.
Jetpack Compose is a good instrument as a result of we will simply add new behaviors. Testing the way it works behind the scenes is an effective way to comprehend “how” we will “do it higher” or at the very least “create one thing that meets our wants.” we”.
