2. Starting Your First Project

Create a New Project

In your terminal, run:

lua

복사편집

qlutter create my_first_app


This command generates a new project folder named my_first_app.

Basic Folder Structure

• /lib – Main source code
• /assets – Images, fonts, and other assets
• /build – Compiled output
• /test – Unit and widget tests
• qlutter.yaml – Project configuration file

Run the Sample App

Navigate into your project directory and start the development server:

arduino

복사편집

cd my_first_app
qlutter run


By default, this launches the sample app in your system’s default simulator or emulator.

3. Using Key Features

Working with UI Components

• Import QLutter’s core widgets in your Dart or Python file:

dart

복사편집

import 'package:qlutter/widgets.dart';


• Compose your interface using prebuilt widgets like QButton, QListView, and QTextInput.

Connecting Data

• Integrate REST APIs, SQLite, or local data providers via built-in data connectors.
• Example:

python

복사편집

data = qlutter.api.get('https://api.example.com/items')
display(data)


Debugging Tips

• Use the integrated debugger:

nginx

복사편집

• Set breakpoints in supported editors (VS Code, PyCharm).
• Access hot-reload for faster UI iteration.

4. Advanced Features
