Compose State-Driven Animation Quiz

This quiz tests your understanding of state-driven animation in Jetpack Compose, focusing on concepts such as the animate*AsState functions, state-based transitions, and advanced animation techniques like keyframes, springs, and easing. It covers how to animate different properties like color, position, and rotation, as well as how to use the updateTransition() function for combining multiple animations. The questions aim to reinforce your knowledge of creating smooth, dynamic animations based on state changes in Compose-based Android apps.
