Welcome to the journey of creating a full-stack eCommerce app with Flutter and Firebase! This guide follows the Flutter Firebase Masterclass course. Together, we will navigate through the project setup, Firebase integration, and Stripe payment implementation.

Getting Started with the Project Setup

First things first! Let’s clone the repository and open it in VSCode. Think of cloning as unfolding a treasure map to an adventure – you’ll have everything you need right at your fingertips. Here’s how to do it:

git clone https://github.com/bizz84/flutter-firebase-masterclass.git
cd flutter-firebase-masterclass
code .

This command will clone the latest code from the main branch of the repository.

Throughout the course, you might need to switch branches to access specific sections of the code. To reset any local changes and switch branches, use the following commands:

git reset --hard HEAD
git checkout branch-name

Firebase Setup

Now we are diving into the core of the app – Firebase! Firebase is like the backbone that holds all the important data and functionality of your app together. For this, some important files need to be generated and positioned correctly:

• lib/firebase_options.dart
• ios/Runner/GoogleService-Info.plist
• ios/firebase_app_id_file.json
• macos/Runner/GoogleService-Info.plist
• macos/firebase_app_id_file.json
• android/app/google-services.json

These files are in the .gitignore, so use the following command to create and configure them:

cd ecommerce_app
flutterfire configure

To ensure the Firebase rules and cloud functions are working, run:

firebase deploy

Integrating Stripe for Payments

As we proceed to add payment functionality, we step into the world of Stripe, which serves as our payment processor. It’s like inviting a trustworthy accountant to handle all of our financial transactions. Here’s how to do it:

For the Stripe integration to function, you need to set a STRIPE_PUBLISHABLE_KEY. This can be done by creating an .env file inside the ecommerce_app folder:

# ecommerce_app/.env
STRIPE_PUBLISHABLE_KEY=pk_test_YOUR_STRIPE_PUBLISHABLE_KEY

Next, run the following command to generate env.g.dart within the lib directory:

dart run build_runner build -d

In case you encounter issues with API keys loading in Flutter web release mode, make sure to refer to the Envied package for the workaround.

Documentation and Support

Troubleshooting Tips

If you encounter errors or unexpected behaviors during the setup, here are a few troubleshooting steps to help you out:

• Ensure that the Firebase configuration files are correctly placed.
• Check your internet connection as sometimes dependency installation requires it.
• Verify that your environment variables are set correctly.
• Consult the community through forums or check the documentation site for common issues.
