Top Highlights

• Compose uses a Modifier object, which is a collection of elements that decorate or modify the behavior of Compose UI elements. You use this to style the UI components of the Dice Roller app's components.

• Chain a fillMaxSize() method onto the Modifier object so that the layout fills the entire screen.

• The wrapContentSize() method specifies that the available space should at least be as large as the components inside of it.

• The Column() function is a composable layout that places its children in a vertical sequence.

• A lambda is a function literal, which is a function like any other, but instead of being declared separately with the fun keyword, it is written inline and passed as an expression.

• Composables are stateless by default, which means that they don't hold a value and can be recomposed any time by the system, which results in the value being reset. However, Compose provides a convenient way to avoid this. Composable functions can store an object in memory using the remember composable. Make the result variable a remember composable. The remember composable requires a function to be passed. In the remember composable body, pass in a mutableStateOf() function and then pass the function a 1 argument. The mutableStateOf() function returns an observable.
