Enhance FlutterFlow App with Connectivity

I'm seeking a proficient developer, ideally with substantial experience in FlutterFlow, Firebase, Google Maps, and connectivity features. My FlutterFlow app presently possesses a UI and design, but the connectivity aspects require refining.

The UI its done, need to create the Data Types and prefer to make reference to make less calls to Firebase.

- Sort by: section (Connectivity)
- Filter (save the filter selection to show on Updates page)
- Page Create Property(UI done already, connectivity)
+ Map put a marker to save the Lat Lng of the Document.
+ Connect the UI and Link it

- Page Edit Property. ( Connectivity)
+ Call Collection Document show on page to edit info in case and update Document (UI done already) - Page Map
+ when press marker pop up card ( same card as the product listing page) when pull down miss the card. + map in zoom in or out markers change icon.

- Page My Properties
+ Call Collection Filter List of Document user create.

- Page Product Listing (Filter Collection in case user hide product)
+ fix favorite icon
+ fix the scroll images carrosuel
+ share button/hide button (hide products)
+ onclick fav icon show Widget tags save on user Document the selected tags

- Page Favorite (Filter Collection show fav Documents using reference to use less call on firebase) if the user is not login show login widget.
