Newton class

The Newton widget is the entry point for creating captivating particle animations.

Use the Newton widget to add and manage different particle effects like rain, smoke, or explosions in your Flutter app. Pass a list of Effect instances to the activeEffects parameter to create the desired particle animations. The Newton widget handles the animation and rendering of the active particle effects on a custom canvas.
