What side effects do you know of when using Jetpack Compose?

Answer from AI
In Jetpack Compose, side effects are operations that affect the external world or state outside the composition, and they need to be controlled to avoid errors and incorrect UI behavior.
The main side effects in Compose:
- LaunchedEffect — launches a coroutine when the key changes, useful for asynchronous operations.
- SideEffect — called after a successful composition, for synchronizing with external state.
- DisposableEffect — allows performing actions when creating and cleaning up the effect, such as registering listeners.
Side effects can lead to:
- Unpredictable UI behavior when state is managed improperly.
- Memory leaks if resources are not released in DisposableEffect.
- Excessive coroutine restarts if effect keys change too frequently.
It is important to use effects correctly to synchronize state and avoid repeated calls.
