Creating the bootstrapper

To configure dependency injection and initialize the Resolver, we need to create a bootstrapper. We will have one shared bootstrapper, as well as other bootstrappers for each platform that meet their specific configurations. The reason we need them to be platform-specific is that we will have different implementations of ILocationTrackingService on iOS and Android. To create a bootstrapper, do the following:

1. Create a new class in the MeTracker project called Bootstrapper.
2. Write the following code in the new class:

using Autofac;
using MeTracker.Repositories;
using MeTracker.ViewModels;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text;
using Xamarin.Forms;

namespace MeTracker
{
    public class Bootstrapper
    {
        protected ContainerBuilder ContainerBuilder { get; private 
        set; }
 
        public Bootstrapper()
        {
            Initialize();
            FinishInitialization();
    ...
