Creating a simple Todo App can be an exciting project, especially when leveraging powerful technologies like **Xamarin** and **Firebase**. Whether you’re a seasoned developer or a beginner, this guide will help you navigate through the process of building your own Todo App. Let’s dive in!

Introduction to the Todo App

The **Todo App** allows users to create an account, log in, manage tasks, and organize them efficiently into lists. Within the app, users can view tasks for specific dates in real-time, edit and delete unwanted tasks using swipe actions, reorder tasks via drag-and-drop, and even filter them from the **More screen**. The **Profile screen** lets users hide completed tasks and provides an overview of total tasks and lists created. Notably, the app supports both **light** and **dark modes**.

Key Features

• Create and manage tasks effortlessly.
• Real-time updates on task lists.
• Edit, delete, and reorder tasks with simple gestures.
• Filter tasks by list from the More screen.
• Profile personalization with task visibility options.
• Dark and light mode for enhanced user experience.

2. Select **Project settings**.
3. Add **Android App** using **com.gheorghedarle.todoapp** as the Android package name.
4. Click on **Register app**.
5. Download google-services.json and place it in the root of the Android project within your solution. Ensure to set its **Build Action** to **GoogleServicesJson** in the file properties.

iOS Configuration

1. Access the Firebase Console.
2. Navigate to **Project settings**.
3. Add **iOS App** with **com.gheorghedarle.todoapp** as the Apple bundle ID.
4. Click **Register app**.
5. Download **GoogleService-Info.plist** and add it to the root of the iOS project in your solution. Set its **Build Action** to **BundleResource** in the file properties.

After completing the setup, don’t forget to enable **Email/Password** sign-in as a provider in the Firebase console:

1. Go to **Authentication** under the **Build** menu.
2. In the **Sign-in method** tab, enable **Email/Password**.

Troubleshooting

If you encounter issues during the setup, here are a few troubleshooting ideas:

• Ensure your Firebase project configuration settings are accurate.
