Plasma 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
      ),
    );
  }
}

Constructors

Plasma({Key? key, int particles = 10, Color foregroundColor = Colors.white, Color backgroundColor = Colors.black, double size = 1.0, double speed = 1.0, double offset = 0.0, int? fps, BlendMode blendMode = BlendMode.srcOver, Widget? child})

const

Properties

backgroundColor → Color

Color of the static background

final

blendMode → BlendMode

The BlendMode that describes how foreground and background merges together.

final

child → Widget?

Prebuild child that's placed inside the Plasma Widget.

final

foregroundColor → 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 setter, inherited

key → Key?

Controls how one widget replaces another widget in the tree.

final, inherited

offset → double

Influences the start position of the particle animation.

final

particles → int

Number of particles to simulate. Has impact on computation demand.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

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

Methods

build(BuildContext context) → Widget

Describes the part of the user interface represented by this widget.

override

createElement() → StatelessElement

Creates a StatelessElement to manage this widget's location in the tree.

inherited

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.

inherited

noSuchMethod(Invocation invocation) → dynamic

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

Returns a one-line detailed description of the object.

inherited

toStringShort() → String

A short, textual description of this widget.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
