Flutter GPS Task App

This Flutter app demonstrates how to use the Google Maps plugin to display a map with the user’s current location and fetch the city name based on the coordinates.

Code Overview

The main code is divided into several components:

MapScreen

• The MapScreen widget is a StatefulWidget that displays the Google Map and the user’s city name.
• It utilizes the GoogleMapViewModel to load the user’s current coordinates and geocoding to fetch the city name.
• The UI consists of a Google Map and a text field displaying the user’s city name.
• The user’s location is marked on the map, and tapping the marker opens a dialog displaying the coordinates.

GoogleMapViewModel

• The GoogleMapViewModel is responsible for interacting with the Google Maps API and obtaining the user’s location.
• It uses the geolocator package to check and request location permissions and to get the user’s current position.
• The loadCurrentUserCoordinates function returns a LatLng object with the user’s current latitude and longitude.

GoogleMapWidget and MarkerCoordinatesDialog

• The GoogleMapWidget is a stateless widget that displays the Google Map using the google_maps_flutter package.
• It also handles the marker for the user’s current location, which can be tapped to show the coordinates in a dialog using the MarkerCoordinatesDialog widget.

main.dart

• The main entry point of the app in main.dart initializes the app and sets up the MaterialApp.
