Hey guys, I want to run `debounce` on a flow from within a Composable. I get this warning
_Flow operator functions should not be invoked within composition ._ I am not using Viewmodels so can’t run the flow operator in the VM. Ideally I’d just want to call `debounce` on the `fullNameFlow` and trigger some changes in the composable. What’s the best way to go forward?
```//This is inside a Composable
val fullNameFlow = MutableStateFlow("")
fullNameFlow.debounce(3000).mapLatest {
    Log.i(TAG,it)
    //Change Composable State
}

FormTextField(
    onValueChange = {
        fullNameFlow.value = it
    }
)```

Reckon you should probably pass a function to your composable that your FormTextField can call within onValueChange, and move your StateFlow into your Fragment or Presenter layer. 


```
@Composable
fun Form(onUpdate: (String) -&gt; Unit){
  FormTextField(){ latest -&gt;
     onUpdate(latest)
   }
}```

You always need to remember state that you create inside a composable, otherwise it will be recreated on every recomposition. 

So eg 
```val fullNameFlow = remember { MutableStateFlow(“”) }
LaunchedEffect(fullNameFlow) {
  // Don't need to remember here because the launched effect lives across recompositions.
  fullNameFlow
    .debounce(3000)
    .mapLatest { … }
    .collect { … }
}
```
