atmospheric_particles 0.3.3

A lightweight and customizable Flutter package for creating beautiful particle animations and atmospheric effects in the background of any widget.

0.3.3

Fixed

• A bug where the fade effect was not correctly applied to particle trails.
• A bug where the fade effect would jump when particles wrapped around the screen. The fade is now calculated per-segment for a smooth effect.

0.3.2

Changed

• Refactor: Replaced AlignmentGeometry with Alignment for the childAlignment property to simplify the API and align with Flutter's best practices.

0.3.1

Changed

• Refactored AtmosphericParticles to use default values for constructor parameters, improving maintainability.
• Added input validation assertions to AtmosphericParticles to prevent invalid parameter combinations.

0.3.0

Added

• Added minParticleRadius and maxParticleRadius properties to AtmosphericParticles to allow for particle size variation.

Changed

• Breaking Change: Replaced particleRadius with minParticleRadius and maxParticleRadius in AtmosphericParticles.

0.2.4

Added

• Added particleShape property to AtmosphericParticles to allow customization of particle shapes (circle, square, triangle, oval, rrect).

0.2.3

Added

• Added trailLength property to AtmosphericParticles to enable and control the length of particle trails.

0.2.2

Added

• Added particlesInFront property to AtmosphericParticles to control whether particles are rendered in front of or behind the child widget.

0.2.1

Fixed

• Particle isolate test hanging due to improper shutdown handling.
• Isolate resource leak by implementing graceful disposal in ParticleCanvas using onExit port.

Changed

• Refactored core particle files into lib/src directory for better project structure.

0.2.0

Added

• Implemented isolate-based animation for improved performance.
• Added a basic test suite for the AtmosphericParticles widget.

Changed

• Refactored the ParticleCanvas to use a long-lived isolate for the animation logic.

0.1.0

Added

• Introduced the FadeDirection enum (top, bottom, left, right, none) to control the direction of the particle opacity gradient.

Changed

• Breaking Change: Replaced the enableVerticalFade boolean property with the fadeDirection property to allow for more flexible fade effects.

0.0.3

Added

• Added the repository field to pubspec.yaml to link directly to the GitHub source code.
• Integrated a direct GitHub link and documentation link into the README.md file.

Changed

• Significantly extended the package description in pubspec.yaml to better explain the package's purpose.

0.0.2

• Added an example/ folder containing a working demonstration.

0.0.1

• Initial Release!
• Added AtmosphericParticles widget to easily add a particle effect background to any widget.
• Added ParticleCanvas for managing particle state and animation loop.
• Added ParticlePainter for custom painting particles onto the canvas.
• Added customization for:
  • particleColor
  • particleCount
  • particleRadius
  • minHorizontalVelocity / maxHorizontalVelocity
  • minVerticalVelocity / maxVerticalVelocity
• Added enableVerticalFade option for a vertical "fade-in" opacity gradient.
