Communication between composable and view-model

• We keep all the states of the widgets in the view model.
• States include data that is populated in the widgets and the boolean states
• We have a public function in the ViewModel that has a sealed class as a parameter where we using which we can invoke a single function with different states and have a when condition to differentiate b/w the different types in view-model.
• We will have a channel in the view model and we observe the channel as a flow in the composable. We basically send data to the channel from the view model and it gets observed as a flow in composable.
• We observe the flow in composable wrapped in launchedEffect because it needs to execute only once should not recompose during every recomposition.
