I have come across articles that recommend switching to StateFlow. Like the one here. Also in the new Android studio, StateFlow support is automatically included in the functionality of data binding, including the coroutines dependencies. Live data is already in use in most of the apps. Should we migrate from LiveData to StateFlow? What are the benefits?
There is not much difference between State Flow and Live Data. The Main difference come in that State Flow requires an Initial value hence no need to check for nullability. The Second Difference come in unregistering the consumer; Live Data does this automatically when the view goes to STOPPED state while State Flow does not. To achieve similar behaviour as Live Data, you can collect the flow in a Lifecycle.repeatOnLifecycle block.
Benefits of State Flow
It depends on what you want,
If you want a manual, full and versatile control over the app , go for state flow
If you want a partially automatic or relatively easy-to-use method for your app , I will say - stick with live data
In case If you want to know my personal opinion, it's state flow, as i prefer control over easy-to-use. I don't mind writing a few extra lines for it as it can be useful for me sometimes.
Think of it like using a soda opener for soda and using a nail cutter I can do it with both but the soda opener Is easy to use in this case but , don't have much versatility like nail cutter.
And at the end of the day , I use state flow everytime because, I am lazy to learn live data for some projects as state flow can do what live data can even though live data will be much easier.
And you should decide what you want to choose and if you're not as lazy as me , I recommend go with both and use the one which is suitable each time.
Cheers.
Flow is the best practice
Livedata is used to observe data without having any hazel to handle lifecycle problems. Whereas Kotlin flow is used for continuous data integration and it also simplified the asynchronous programming.
Take Room Library as an example. First, it used livedata to transmit data from the database to UI. It solved most of the existing problems. But when there are any future changes in the database livedata is helpless in this situation.
After a while, the room used Kotlin flow to solve this problem. With Flow as return-type, room created a new possibility of seamless data integration across the app between database and UI without writing any extra code
