go to user flutter sdk path
.pub-cache/hosted/pub.dartlang.org/MapViewPlugin.kt

replace this val cameraDict = mapOptions["cameraPosition"] as Map<String, Any>
with
val cameraDict = mapOptions["cameraPosition"] as Map<String, Any>

go to user flutter sdk path
.pub-cache/hosted/pub.dartlang.org/MapViewPlugin.kt

replace this val cameraDict = mapOptions["cameraPosition"] as Map<String, Any>
with
val cameraDict = mapOptions["cameraPosition"] as Map<String, Any>

both are same lines... what are saying to replace

[Saddi993]

go to user flutter sdk path
.pub-cache/hosted/pub.dartlang.org/MapViewPlugin.kt

replace line no 167 to 180 with this code:

            val mapOptions = call.argument<Map<String, Any>>("mapOptions")
            val cameraDict = mapOptions!!["cameraPosition"] as Map<String, Any>
            initialCameraPosition = getCameraPosition(cameraDict)
            toolbarActions = getToolbarActions(call.argument<List<Map<String, Any>>>("actions"))
            showUserLocation = mapOptions!!["showUserLocation"] as Boolean
            showMyLocationButton = mapOptions!!["showMyLocationButton"] as Boolean
            showCompassButton = mapOptions!!["showCompassButton"] as Boolean
            hideToolbar = mapOptions!!["hideToolbar"] as Boolean
            mapTitle = mapOptions!!["title"] as String

            if (mapOptions!!["mapViewType"] != null) {
                val mappedMapType: Int? = mapTypeMapping.get(mapOptions!!["mapViewType"]);
                if (mappedMapType != null) mapViewType = mappedMapType;
            }

it works for me
