How to Enable ctr + scrollwheel to zoom in Google Maps Api

Question

Hi im using Google Maps API https://angular-maps.com/, and i want to zoom only while pressing ctrl + scrolling with the scrollwheel. Reading the documentation I have found this:

gestureHandling This setting controls how gestures on the map are handled. Allowed values:

'cooperative' (Two-finger touch gestures pan and zoom the map. One-finger touch gestures are not handled by the map.) 'greedy' (All touch gestures pan or zoom the map.) 'none' (The map cannot be panned or zoomed by user gestures.) 'auto' [default] (Gesture handling is either cooperative or greedy, depending on whether the page is scrollable or not. Type: |||

Default value: auto

so in my code i added :

<agm-map
    [latitude]="lat" 
    [longitude]="lng"
    [zoom]="zoom"
    [gestureHandling]="cooperative"
    [mapTypeControl]="true"
    [mapTypeControlOptions]="mapType"
    >

but is not working, it does not ask me to press ctrl to zoom.

Answer 1

Setting [scrollwheel]="null" seems to work for now.
