Developer.Implement chain for #54

Below is the bash script that sets up a Xamarin.Forms project named TodoListMobileApp and implements basic views and view models for Todo list management. This script will create a project structure and provide template files for a simple application that follows MVVM architecture.

Please note, this script assumes you have the dotnet CLI and Xamarin tools installed. You won't be able to run this script directly on a system that doesn't have these prerequisites.

#!/bin/bash

# Create a new Xamarin.Forms project
dotnet new sln -n TodoListMobileApp
mkdir TodoListMobileApp
cd TodoListMobileApp
dotnet new xamarinforms -n TodoListMobileApp
dotnet sln add ./TodoListMobileApp/TodoListMobileApp.csproj

# Create folders for Views and ViewModels
mkdir TodoListMobileApp/Views
mkdir TodoListMobileApp/ViewModels

# Create a TodoItem model
echo 'namespace TodoListMobileApp.Models
{
    public class TodoItem
    {
        public string Id { get; set; }
        public string Title { get; set; }
        public bool IsDone { get; set; }
    }
}' > TodoListMobileApp/Models/TodoItem.cs

# Create TodoListViewModel
echo 'using System.Collections.ObjectModel;
using TodoListMobileApp.Models;

namespace TodoListMobileApp.ViewModels
{
    public class TodoListViewModel
    {
        public ObservableCollection<TodoItem> TodoItems { get; } = new ObservableCollection<TodoItem>();

        public TodoListViewModel()
        {
            // Ideally, items would be fetched from a data service
            // For simplicity, we are adding items manually for now
            TodoItems.Add(new TodoItem { Id = "1", Title = "Learn Xamarin", IsDone = false });
            TodoItems.Add(new TodoItem { Id = "2", Title = "Build Todo App", IsDone = false });
            TodoItems.Add(new TodoItem { Id = "3", Title = "Review best practices", IsDone = false });
        }
    }

# Create TodoListView
echo 'using Xamarin.Forms;

namespace TodoListMobileApp.Views
{
    public class TodoListView : ContentPage
    {
        public TodoListView()
        {
            BindingContext = new TodoListViewModel();

            var listView = new ListView();
            listView.SetBinding(ListView.ItemsSourceProperty, "TodoItems");

            // Define template for displaying each item
            listView.ItemTemplate = new DataTemplate(() =>
            {
                var titleLabel = new Label();
                titleLabel.SetBinding(Label.TextProperty, "Title");

                var checkbox = new CheckBox();
                checkbox.SetBinding(CheckBox.IsCheckedProperty, "IsDone");

                return new ViewCell
                {
                    View = new StackLayout
                    {
                        Orientation = StackOrientation.Horizontal,
                        Children = { titleLabel, checkbox }
                    }
                };
            });

            Content = listView;
        }
    }
}' > TodoListMobileApp/Views/TodoListView.cs

# Update MainPage to use TodoListView
echo 'using TodoListMobileApp.Views;
using Xamarin.Forms;

namespace TodoListMobileApp
{
    public partial class App : Application
    {
        public App()
        {
            MainPage = new NavigationPage(new TodoListView());
        }
    }
}' > TodoListMobileApp/App.xaml.cs

echo "Xamarin.Forms project 'TodoListMobileApp' created with basic Todo list management views and view models."

Save this script in a file, give it execute permission using chmod +x scriptname.sh, and run it with ./scriptname.sh in a compatible environment. This will generate a basic skeleton for the TodoListMobileApp with views and view models, following the MVVM pattern.
