A Flutter GPS Task App for retrieving the user's current location and displaying it

by Flutter Awesome

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.
