Map Me - Flutterized

🌎 This project is a Flutterized version of the Map Me project. Tracks your location and see details of the route: speed, elapsed time and distance covered. The goal of the project is to practice recreating the UI elements of this image and getting familiar with the google_maps_flutter package. (No data gets saved!)

Screenshots (with a fake location ofcourse)

Download

Because of the Google Maps API Key, it could cost me if there are a lot of users the app. So for the meantime, I'll keep the APK in Releases and might remove it after some time.

Features ✔️

Detect the current location of the user
Draw the route between start location and current location using Polylines
Calculate the actual distance of the route
Stopwatch to time the walk

Comments

The architecture can be improved. Since it's only possible to get the dart GoogleMapsController from the widget itself, I wasn't able to keep all logic-code inside the BLoC. I need to research a better solution to separate the UI and business logic. However the ultimate goal of practising with the UI elements and the google_maps_flutter package has been achieved! 😎

Also, this app works on both Android & IOS. However, the IOS version hasn't been fully tested for functionality.

How to Build 📱

Note that you need to make a new project in the Google Cloud Platform, and enable the Google Maps API for that project. Then you need to copy the API Key and add it to the code in multiple locations:

Add the key to this file lib/util/constants.dart:

  static const String APIKEY = "<-- YOUR API KEY -->";

Next go to the Android manifest file android/app/src/main/AndroidManifest.xml and add your API key here:

<meta-data android:name="com.google.android.geo.API_KEY"
             android:value="YOUR KEY HERE"/>

Lastly, go to the file Runner/AppDelegate.swift and add your API key there as well:
```
  GMSServices.provideAPIKey("<-- YOUR API KEY -->")
```
