// Common mistakes when using Flow in Android
// 1. Not collecting Flow in a Lifecycle-aware manner
lifecycleScope.launch {
viewModel.someFlow.collect { value ->
// Handle the value
}
}
// 2. Using Flow without error handling
someFlow.catch { e ->
// Handle errors appropriately
}
// 3. Forgetting to stop collecting Flow in onStop
override fun onStop() {
super.onStop()
job.cancel() // Remember to cancel jobs to prevent leaks
}
// 4. Blocking the main thread with Flow.collect
withContext(Dispatchers.Main) {
someFlow.collect { value ->
// Update UI with value
}
}
// 5. Not using sharedFlow or stateFlow where suitable
val sharedFlow = MutableSharedFlow()
