Design and Code Structure (Archived)

​

Initial Setup

​

Step 1: Designing with Cades

First, describe your app idea to Cades and let it generate the initial screens.

For VideoGPTAI, the following screens were created:

• Home Screen (template selection)
• Library Screen (user’s videos)
• Review Screen (video preview)
• Settings Screen (user profile)
• Login Screen (authentication)

Click on the Finalize Designs & Generate Code button to generate the code for your mobile app.

​

Step 2: Understanding the Code Structure

lib/
├── common/
│   ├── constants.dart
├── main.dart
├── pages/
│   ├── home_screen.dart
│   ├── library_screen.dart
│   ├── login_screen.dart
│   ├── onboarding_screen.dart
│   ├── review_video_screen.dart
│   └── settings_screen.dart
└── styles/
    └── theme.dart

When you generate code from your designs, you get a complete Flutter project structured in a way that’s easy to work with. In the lib folder, we have these main parts:

• common: This folder contains shared elements like app constants, which are used throughout the app to maintain consistency and avoid hardcoding values.
• pages: This folder contains all our screen designs. Each screen is represented by a Dart file, making it easy to manage and update individual screens.
• styles: This folder includes our theme file, which keeps all our design choices consistent across the app. It defines colors, fonts, and other styling elements.
• main.dart: This is the entry point of the app, where all the components are connected and the app is initialized.

Now that we understand the structure, let’s start updating our app…

Step 3: Basic Project Configuration

Configure your app’s identity with the following prompt:

Change the name and description of the project in pubspec, and update all imports in main.dart and use the change_app_package_name to update it
name in pubspec should be in lowercase and underscore

My project name is "videogptai"
Description: "AI-powered video creation app"
My project package name will be "com.videogptai.android"
