Concepts involved in application

Role of reactive data source

• The reactive data source is very useful in keeping the code decoupled
• We can keep the data in the view model as reactive and make it such a way that it is being observed in the view layer(activity/fragment)
• This way we can prevent memory leaks
• A memory leak happens when the fragment is destroyed and the reference is kept in the view model

Usage of the channel in the view-model to show a one-time message

• We use a methodology where we keep a channel in the view model we make it private and such a way that user won't be able to add values to the channel
• By converting the channel to flow and making it public user can observe the value in the fragment and not add values in the fragment.
