Creating a radio button

In Modern Android Development, RadioButton is used similarly to how it is used in traditional Android development. RadioButton allows users to select a single item from a list of mutually exclusive options, meaning only one option can be selected at a time.

In Jetpack Compose, RadioButton is part of the Material Design library and can be used by importing the Androidx.compose.Material.RadioButton package. To create a group of RadioButton instances, you would typically use the RadioGroup composable, which is also part of the Material Design library.

The RadioGroup composable takes a list of options as input, along with a selected option and a callback that is called when the selected option changes. The individual RadioButton instances can be created using the RadioButton composable and added as children of RadioGroup.
