Android: updateMap() calls in removeGraphic delays method call result

[JulianBissekkou]

The calls for adding or removing a graphic take longer on android than they do on iOS.
This is due to a workaround what in some cases the map is not beeing refreshed and we therefore refresh the map manually.

arcgis_map_sdk/arcgis_map_sdk_android/android/src/main/kotlin/dev/fluttercommunity/arcgis_map_sdk_android/ArcgisMapView.kt

Line 522 in aa37a15

updateMap().onSuccess { updateResult ->

    private fun onRemoveGraphic(call: MethodCall, result: MethodChannel.Result) {
        /*Other code */
        // Don't use removeAll because this will not trigger a redraw.
        graphicsToRemove.forEach(defaultGraphicsOverlay.graphics::remove)

        lifecycle.coroutineScope.launch {
            updateMap().onSuccess { // <------
                result.success(true)
            }.onFailure { e ->
                result.finishWithError(e)
            }
        }
    }

• See if this workaround is still required after the recent arcgis update
• If its required, run updateMap after we called result.success and ignore the error of that call
