Activities to be performed:
1) Upgrade the app from ionic 3 to ionic 4
2) Change the notofication service from Push woosh to firebase.
3) Currently because ionic 3 is not compatible with firebasex cordova plugin, the notifications are not coming on IOS platform. upgrading to ionic 4 will solve this problem.
4) Search shop feature needs to be changed. At present app searches the backend database of sellers in that area and shows results. Now the problem is that the seller registration to the app is not picking up so we need to use the google map to provide the buyer with search results on nearby shops. when the buyer searches any shop, the app should search the backend and google maps both for particular query at the location of buyer and display results, from database of registered sellers and google maps. in the search results buyer must be able to call, find address and pick location.
