confetti 0.8.0

Blast colorful confetti all over the screen. Celebrate in app achievements with style. Control the velocity, angle, gravity and amount of confetti.

[0.8.0]

⛔️ Breaking!

• Added the concept of delta time, to allow for better simulation when the refresh rate is 120 (or more than 60). There should be no noticable change on a 60fps screen, however, there may be variance if Flutter drops frames. No changes needed from a widget level.
• ParticleSystem.update and Pariticle.update now contain a deltaTime argument. No changes needed from a widget level.
• Some visual difference, as now not all particles will rotate on the z-axis (50% chance). This change was maded to enhance visual fidelity.

⭐️ Added

• clearAllParticles added to stop method on controller: _confettiController.stop(clearAllParticles: true); default is false. If true particles will immediately be cleared/removed on stop. Calling dispose will also clear all particles immediately.
• particleStatsCallback added to Confetti widget to retrieve the ParticleStats. This provides info on the particle system, such as number of active and number of total particles in memory.
• pauseEmissionOnLowFrameRate to Confetti widget. Default is true. This will pause additional confetti emission if the frame rate is below 60fps, and will continue when resources are available. This can be disabled by setting to false, to force particle creation regardless of frame rate.

⚡️ Improved

• Various performance improvements!
  • Confetti is now conditionally reused instead of recreated, big improvement
  • 120hz refresh rate supported
  • pauseEmissionOnLowFrameRate boolean added to Confetti widget to ensure smooth 60 FPS. This may however result in no confetti appearing if other complex operations are taking up resources. Set to false to disable.
  • Temporary fix for issue [#66] with severe perf issues on Chrome macOS.

[0.7.0]

⭐️ Added

• Stroke width and color can now optionally be set. strokeWidth (default 0) and strokeColor (default black). Requires a stroke width bigger than 0
• Updated to Flutter 3.0

[0.6.0]

🔄 Changed

• Removed the random_color package and replaced with custom logic. Random colors may now be slightly different.
• Updated dependencies

🐞 Fixed

• Unmounted exception (https://github.com/funwithflutter/flutter_confetti/issues/36). Thanks Iiropel.
• Moved .super call to the top of initState.

[0.6.0-nullsafety]

Now with null safety :) - Thanks Ali1Ammar!

[0.5.5]

Add optional createParticlePath function to pass in a custom Path for the conveti (for example a Star path, instead of the default Rectangle path). Example updated. Thanks Artur-Wisniewski. Fix: Animation stop event not firing. Thanks WieFel.

[0.5.4+1]

Fix: Call play on the confetti controller from initState.

[0.5.4]

Fix: Confetti emitter position set incorrectly when transitioning to a new PageView. The emitter position is now set on animation start. Fix: Set ConfettiControllerState.stopped on ConfettiWidget dispose.

[0.5.3]

Add canvas parameter.

[0.5.2]

Fix where at certain times the Confetti widget takes too long to emit. This update ensures that particles are generated on the first frame, and when there are no longer any particles on the screen but the animation is still running.

[0.5.1]

Fixed layout issue where the screen size and confetti position were not updated on layout changes. The package will now respond to screen layout and sizing changes.

[0.5.0]

Massive performance improvements. Should see a significant performance boost when running the application in profile/release mode. It is now possible to add a lot more confetti without the application causing jank. It is recommended to test the use of this package on multiple devices, to ensure it does not introduce performance issues on older devices.

[0.4.0]

This update will result in a change in the default falling speed (gravity) and drag of the confetti. You may note a difference, and might be required to modify some of these paramaters to achieve the desired result

• Added an optional gravity to change the speed at which the confetti falls
• Added an optional blastDirectionality property. The default is BlastDirectionality.directional where you can specify a blastDirection to shoot the confetti in a specific direction. Change to BlastDirectionality.explosive to blast confetti in random directions
• Added an optional particleDrag property to configure the drag to apply to the confetti

[0.3.0]

• Provide an optional minimumSize and maximumSize to customize the size of the confetti. For example, setting a minimumSize equal to Size(10,10) and a maximumSize equal to Size(20,20) will create confetti with a size between these two parameters. Can be provided as an argument in the ConfettiWidget

[0.2.0]

• Provide an optional Color List to specify specific colors for the confetti. A single color, for example [Colors.blue], or multiple colors [Colors.blue, Colors.red, Colors.green] can be provided as an argument in the ConfettiWidget

[0.1.2]

• Provide optional child widget to render below the confetti
• Changed the painter to use foregroundPainter to always paint the confetti above its child

[0.1.1]

• Patch null pointer exception

[0.1.0]

• Initial release. You will probably experience some performance issues if you try and create too many particles at once
• Performance optimization work will be done in later versions.
