A Flutter application that simulates the movement and interaction of particles based on mouse position. Particles are attracted to the mouse or to a calculated point if the mouse is not moving. This project demonstrates the use of Flutter's CustomPainter for custom drawing and GestureDetector for handling user interactions.
- Flutter installed on your machine. If you don't have Flutter installed, follow the instructions on the official Flutter website.
-
Clone the repository:
git clone https://github.com/hamed-rezaee/flutter_particle_attraction_simulation.git
-
Install the dependencies:
flutter pub get
-
Run the app:
flutter run
main: Entry point of the application. Sets up the main widget and handles particle logic.Particle: A class representing an individual particle.ParticleAnimation: A stateful widget that manages the particle system and user interactions.ParticlePainter: A custom painter that renders the particles on the canvas.
You can customize the behavior and appearance of the particles by modifying the following constants in ParticleAnimation:
rows: Number of rows of particles.cols: Number of columns of particles.numParticles: Total number of particles (rows * cols).thickness: Attraction strength. Increase for stronger attraction.spacing: Distance between particles.margin: Margin around the particle grid.color: Color intensity of the particles.drag: Damping factor for particle movement.ease: Ease factor for particle movement.
