PlasmaRenderer class

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 'dart:math';
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
      ),
    );
  }
}

const

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.
no setterinherited
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.
no setterinherited
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

override
createElement() → StatelessElement
Creates a StatelessElement to manage this widget's location in the tree.

debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.

Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
