Anyone managed to use android databinding with binding to

StateFlow

or

MutableStateFlow

properties? I've created custom binding adapters before, but i cannot get it to work properly with StateFlows

What doesn't work exactly?

I couldnt get two-way binding to work. Usually you would have something like:

@InverseBindingAdapter(attribute = "flowText")
@JvmStatic
fun getText(view: MyEditText): String {
    return view.text.toString()
}

@BindingAdapter("flowText")
@JvmStatic
fun setText(view: MyEditText, newValue: String) {
    if (view.text.toString != newValue) {
        view.text = newValue
        view.textChangedListener?.onChange()
    }
}

@BindingAdapter("flowTextAttrChanged")
@JvmStatic
fun setListeners(
    view: MyEditText,
    attrChange: InverseBindingListener
) {
    view.textChangedListener = attrChange
}

But when replacing

String

with

MutableStateFlow<String>

the InverseBindingAdapter would never be called or used by the generated binding code

Thats why I use LiveData, it has out of the box db support

Right, i use LiveData for native android app's but for KMP i'd like to share the viewmodels between platforms... not possible with LiveData

You have

flow.asLiveData()

But surely that cannot be used in common code right? I'd have to do that in the android code

Yea, just like you use BindingAdapter

Right. Hmm its an interesting option for sure, thanks

@Mgj You can make your own

asMutableLiveData

if you want.

Should probably have made it more clear, its what i meant by "bindingAdapter-like code". Its still a cool idea but loses some of its appeal
