How to get the new coordinates of draggable marker in Jetpack Compose?

Question

I have the following marker that is added successfully on a Google Map:

Marker(
    state = MarkerState(
        position = LatLng(lat, lng)
    ),
    title = "Party",
    snippet = "Come to party.",
    draggable = true
)

I set this marker to be draggable and it works, but how to know the new coordinated when the marker is dropped?

Answer 1

I think this can be done by remembering the marker state you are passing to the Marker; for instance, you can write the following code and query the state for the new coordinates or pass that state to where you want to get the updates:

val markerState = rememberMarkerState(position = LatLng(lat, lng))
Marker(
    state = markerState
    title = "Party",
    snippet = "Come to party.",
    draggable = true
)

That way, on every recomposition, upon dragging the marker, the new position will be in the markerState.

I hope this helps!
