243243A ` LiveData ` property that exposes the ` UiState ` in the ` ViewModel ` is created by using the ` .asLiveData() ` terminal operator.
244244This use case also shows how to use the ` map ` intermediate operator and the ` onStart ` lifecycle operator.

248251The second use case is an extension of the first one.
249252It uses some basic intermediate operators, like ` withIndex ` , ` map ` , ` take ` and ` filter ` .

253259The third use case shows how to properly implement exception handling with flows.
254260
255261It uses the ` catch ` operator to handle exceptions of our flow in the ` ViewModel ` and uses the ` retry ` operator to retry failed network requests in the ` DataSource ` .

258267
259268This use case shows how to expose flows (a ` StateFlow ` to be precise) in the ` ViewModel ` instead of a ` LiveData ` property.
260269The ` statIn ` operator is used to convert the ordinary, cold ` Flow ` into a hot ` StateFlow ` .

262271In the ` Activity ` , the ` repeadOnLifecycle ` suspend function is used to collect emissions of the ` StateFlow ` in a lifecycle-aware manner.
