PlasmaRenderer class Null safety

Plasma creates an animation with moving particles that generates a smooth liquid effect. It can be configured in many styles.

You can also use a non-animating variant by setting speed to 0.0 and find a good looking position with the offset.

Example:

import 'package:flutter/material.dart';
import 'package:simple_animations/simple_animations.dart';

void main() => runApp(MaterialApp(home: Page()));

class Page extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Plasma(
        particles: 10,
        foregroundColor: Color(0xd61e0000),
        backgroundColor: Color(0xffee360d),
        size: 0.87,
        speed: 5.92,
        offset: 0.00,
        blendMode: BlendMode.darken,
        child: Center(child: Text("Hot!")), // your UI here
      ),
    );
  }
}

Properties

blendMode BlendMode
Describes how the color merges.
final
blur double
Blur scale of the particle.
final
child Widget?
Child that's placed inside this Widget.
final
color Color
Color of the animating particles
final
fps int?
If set, the animation will reduce the framerate (fps) to the specified value.
final
hashCode int
The hash code for this object.
@nonVirtualread-onlyinherited
key Key?
Controls how one widget replaces another widget in the tree.
finalinherited
offset double
Influences the start position of the particle animation.
final
particles int
Number of particles to simulate. Has impact on computation demand.
final
particleType ParticleType
Method used to render each particle.
final
rotation double
Rotation of the animation in radians
final
runtimeType Type
A representation of the runtime type of the object.
read-onlyinherited
size double
Size scale of the animating particles. Has slight impact on computation demand.
final
speed double
Speed scale of the animation. You can set it to 0.0 that disable the animation. Disabled animations doesn't require computational demand at all.
final
type PlasmaType
Type of plasma animation
final
variation1 double
Number influencing the rendering of certain Plasma types.
final
variation2 double
Number influencing the rendering of certain Plasma types.
final
variation3 double
Number influencing the rendering of certain Plasma types.
final
