// 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()
```
