This is a Countdown timer app which counts time in format (HH : MM : SS) . When we clicks on the time its shows a popup for set counter time.
This app is purely made on android jetpack compose with ViewModel and LiveData .
For using them we have to add dependencies :
implementation "androidx.compose.runtime:runtime-livedata:$compose_version"
implementation "androidx.lifecycle:lifecycle-viewmodel-compose:1.0.0-alpha02"
