Project Overview

This is a Flutter project that demonstrates how to use custom shaders. The shaders are taken from the ShaderToy community and adapted for Flutter. The application displays a grid of shader examples, and tapping on each one opens a detailed view.

Key Technologies:

• Flutter
• GLSL (OpenGL Shading Language)

Architecture:

• The main entry point is lib/main.dart, which sets up the application and the home page.
• The home page (HomePage) displays a GridView of ShaderPage widgets.
• Each ShaderPage can be a GeneralShaderPage or an ImageShaderPage, depending on whether it uses an image as a texture.
• The shaders are located in the shaders directory and are defined in .frag files.
• Assets, including images and shaders, are declared in pubspec.yaml.
• The lib/config/assets.dart file contains a class with static constants for asset paths, which is a good practice for managing assets.

Building and Running

To build and run this project, you need to have the Flutter SDK installed.

1. Get dependencies:

   flutter pub get

2. Run the app:

   flutter run

Testing:

To run the tests, use the following command:

flutter test

Development Conventions

• Asset Management: Asset paths are managed in the lib/config/assets.dart file. When adding new assets, declare them in pubspec.yaml and then add a corresponding constant to the Assets class.
• Shaders: Shaders are written in GLSL and have the .frag extension. They are located in the shaders directory. To add a new shader, you need to add it to the shaders directory and declare it in the pubspec.yaml file.
• Code Style: The project follows the standard Dart and Flutter code style. The analysis_options.yaml file includes flutter_lints for enforcing good coding practices.
