Set map radius using pinchin gesture



I am trying to use onGesture(pinchin, callback, element) to set a colored radius area within a google or leaflet- and then translate this radius number to search nearby restaurants using the foursquare api. is this possible using only ionic foursquare google maps?


You could set something up based off of this. Keep in mind you need to replace dragleft and dragright with the pinch gestures.
