Answer from AI
LaunchedEffect is an effect in Jetpack Compose that launches a coroutine on first composition or when the key changes. It is used for executing side effects, such as asynchronous operations, that should run in response to state changes.
Example usage:
LaunchedEffect(key1 = someState) {
// This block will run on first composition and when someState changes
val data = fetchData()
// update UI state
}
Thus, LaunchedEffect helps to launch coroutines tied to the lifecycle of the composition and automatically cancels them when the component is destroyed or the key changes.
