Explore clipping and shapes by building an avatar with a box, image, and circle clipping, adjusting color, opacity, border, and shadow to create a polished avatar.

Create a decorated text examples composable in Jetpack Compose using a column with padding to demonstrate underline, line-through, none, and combined decorations with italic typography.

Learn how to add a circle in jetpack compose by using spacer, modifiers for height and size, a blue background, and horizontal centering to create a centered circular shape.

Explore enum classes in Jetpack Compose by building a direction enum with north, east, south, and west, tracking the current direction with remember and mutable state, and updating via buttons.

Explore sealed classes in Kotlin to model safe, compile-time known state in a Jetpack Compose UI, using a screen state with loading, success, and error variants.

Explore sealed interfaces to model UI state in Android, enabling lightweight, flexible state machines. Define a singleton state and data classes for success or error, using multiple inheritance and when.

Build a mood map app that defines moods, deletes moods, and shows mood statistics bar and pie charts, with scaffolding including snack bar, top bar, and a floating action button.

Create a Jetpack Compose UI that accepts a number input, validates it, and shows whether it is divisible by seven, using stateful text fields, a button, and a gradient background.

Develop Kotlin logic functions to determine divisibility by a given divisor, handle division by zero, and return a range-based list of results for values from min to max, excluding max.
