How to increase zoom per click of tool bar for SfMaps?

Hello,

I am using your SfMaps module with a world.json from your examples.

I am using the toolbar to zoom in and out on MacOS. 

I notice when clicking "Zoom in" on the toolbar, the onWillZoom, will have the same previous zoom value and next zoom value which seems like a bug.

I have also noticed that the zoom in is 0.5 for toolbar zoom in but 1.0 for double tap.

Is there a way to alter the zoom in value? Maybe even more zoom when zoomed out and less when zoomed in.

Thanks

SfMaps(

layers: <MapLayer>[
MapShapeLayer(
onWillZoom: (z) {
z.previousZoomLevel == z.newZoomLevel;
},

Hi again,


Is there a way to make increase the zoom level on every click?

I find the zoom experience weird on a world map. It zooms in quickly at first then very slowly as it nears maximum zoom.

Any ideas?

We have checked the world map by increasing the zoom level at every click with the previously shared sample and it is working fine without any issues. We kindly request you to share more information about the issue reproduction steps along with screenshots or screen recordings so that it will help us assist you in a better way. Also, shared the sample which is used for testing purposes.
