Mastering FlutterFlow and Supabase: Build a Skill Swap App

This cheatsheet aims to condense the essential information and insights from the tutorial on building a complex app using FlutterFlow and Supabase, specifically focused on creating a skill-swapping application. Whether you are a beginner or have some experience with app development, this guide is crafted to help you grasp the key concepts, steps, and practical applications.

🏆 Key Concepts of the Skill Swap App

Understanding User Flow

Before diving into coding, always start with the user flow. In our Skill Swap app, we allow users to exchange skills. Users log in, provide their skills, and search for others offering what they need. They can schedule sessions, chat, and leave reviews.

User Flow Steps:

1. User authentication.
2. Profile setup.
3. Browsing skills.
4. Matching and messaging.
5. Scheduling sessions and reviews.

User Interaction with Database

To build any app effectively, understanding the database schema is crucial. In this app, Supabase, a back-end service, helps manage data efficiently:

• Entities:
• Users: Stores user credentials and profiles.
• Skills: Encapsulates the skills offered by users.
• Sessions: Manages scheduled meetings between users.
• Favorites: Saves user preferences for future reference.

Relationships:
Utilize many-to-many relationships effectively (e.g., a user can have multiple skills and vice versa).

Authentication & Security

Utilizing Supabase for authentication ensures secure user sign-in and data handling. Remember to set Row-Level Security (RLS) policies to ensure users only access their data.

Implementing Push Notifications

Integrating push notifications using Firebase Cloud Messaging informs users about relevant events (e.g., new messages, session updates). This enhances user engagement.

Steps for Implementing Push Notifications:

1. Create an FCM project in Firebase.
2. Set up necessary service prompts for notifications.
3. Integrate push notification logic into the application.

🔧 Practical Tips & Implementations

1. Setting Up Supabase

• Create and configure your Supabase database.
• Define the schema accurately to include all necessary entities and relationships.

2. FlutterFlow Connection

• Connect FlutterFlow to your Supabase instance.
• Peruse the UI components of FlutterFlow to create your desired screens, maintaining the focus on user experience.

3. Building the User Interface

• Use Grid Views for displaying multiple offers.
• Ensure responsive design practices are adhered to so it looks good across devices.
• Capture user interactions (favoriting skills, messaging, etc.) using buttons and dynamic widgets.

4. Utilizing Actions and Callbacks

• Design your app to handle various user actions, leveraging FlutterFlow’s robust action system.
• Ensure to include text input fields for messaging and provide clear feedback to the user when they send messages.

5. Testing & Iteration

• Test the app’s functionalities frequently.
• Use simulators to validate push notifications and user interactions.
