Have you ever wanted to create your very own Instagram clone? Fluttergram serves as an excellent starting point to bring that idea to life using Flutter and Firebase. This guide will walk you through the setup process step-by-step, making it user-friendly, and providing troubleshooting tips along the way.

Getting Started

Before diving into the code, here’s what you need to do to set everything up:

1. Install Flutter

• Follow the official instructions on how to setup Flutter.

2. Clone the Repository

• Open your terminal and run:

$ git clone https://github.com/mdanics/fluttergram.git

• Navigate into the project folder:

$ cd fluttergram

3. Set Up Your Firebase App

• Create a Firebase instance by following the instructions at Firebase Console.
• Enable Google authentication through the Firebase Console → Authentication → Sign-in method → Google → Enable.
• Create Cloud Functions for the feed:
• Create a new Firebase project with firebase init.
• Copy the functions from lib/index.js in the Fluttergram repo to your project’s functions/index.js.
• Deploy the function using firebase deploy –only functions.
• Replace the URL in the _getFeed function in feed.dart with your Cloud Function URL.

4. Enable the Firebase Database

• In Firebase Console, click on Database → Create Database → Start in Test Mode → Enable.

5. Android (Skip if not applicable)

• Create an Android app within your Firebase instance with package name com.yourcompany.news.
• Run the command to get your SHA-1 key:

keytool -exportcert -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore

• In the Firebase console, add your SHA-1 key in the app’s settings.
• Download google-services.json and place it into android/app.

6. iOS (Skip if not applicable)

• Create an iOS app within your Firebase instance with your app package name.
• Download GoogleService-Info.plist and add it to XCode’s Runner folder.
• Update the Info.plist with the reversed client ID from your plist file.

Understanding the Code: An Analogy

Think of Fluttergram as a recipe for a delicious cake. Just as a cake requires specific ingredients (like eggs, flour, and sugar), Fluttergram relies on various Flutter packages and Firebase features. Each package serves as an ingredient that helps deliver the final product:

• Image Picker: The eggs that help bind the mixture together.
• Firestore: The flour that provides structure and holds everything in place.
• Firebase Auth: The sugar that sweetens the process, by enabling user authentication.

Just as baking requires careful mixing and timing, Fluttergram requires precise integration of these dependencies to yield a functional Instagram clone.

Troubleshooting Common Issues

• Error: Error parsing triggers: Cannot find module .notificationHandler: This can happen due to missing files or incorrect paths. Try following these steps.
• If you encounter an empty feed with no errors, ensure you have posted photos or are following users with posts. The feed will only show your posts or posts from followed users.
