Architecture and state

1. In Compose, there is no way to update the UI after it’s been drawn without changing state.

   True

   False

2. Which of the following is true about unidirectional data flow (UDF):

   Choose as many answers as you see fit.

   It’s difficult to test state and the UI that displays in isolation.

   There is only one source of truth for the state of a composable.

   Not all state updates are immediately reflected in the UI.

   It’s less likely that you’ll create bugs due to inconsistent states

3. Compose has a special state-tracking system in place that schedules recompositions for any composables that read a particular state.

   True

   False

4. When state changes, a recomposition is triggered to:

   Choose as many answers as you see fit.

   Display the new data on the screen

   Recompose just those composable functions that need to change

   Recompose the entire UI

   Update the properties of a view

5. State is always mutated inside the scope of a composable function.

   True

   False

   mutableStateOf

   mutableListOf
