Countdown Timer
📜 Description
An application built with Jetpack Compose that allows you to set a timer (minutes and seconds).
💡 Motivation and Context
The countdown timer is made up by a selection screen where user can select a value for minutes and seconds. The 'Play FAB' is only visible if user select a countdown value greater than 0:00. This change in visibility is based on a 'fade in' and 'expand in' animation.
Once Play FAB is clicked, the countdown begins and an animated progress bar that fills the screen size will shrink with the progress. User can see the time remaining and every second the text is updated with an animation. The countdown can be also paused or restarted to set another value.
Finally, when countdown reaches 0:00, an infinite animation is launched and user will see the ‘0:00’ with a blinking effect.
