dependencies:
  floating_bubbles: ^2.5.1

Import the package:

import 'package:floating_bubbles/floating_bubbles.dart';

Usage

Here is an snippet on how to use Floating Bubbles to any Widget.

Creating FloatingBubbles() (this creates the animation and plays for amount of time you give as the duration.)

 return Stack(
    children: [
     Positioned.fill(
        child: Container(
        color: Colors.red,
      ),
     ),
     Positioned.fill(
         child: FloatingBubbles(
         noOfBubbles: 25,
         colorsOfBubbles: [
            Colors.green.withAlpha(30),
            Colors.red,
         ],
         sizeFactor: 0.16,
         duration: 120, // 120 seconds.
         opacity: 70,
         paintingStyle: PaintingStyle.stroke,
         strokeWidth: 8,
         shape: BubbleShape.circle, // circle is the default. No need to explicitly mention if its a circle.
         speed: BubbleSpeed.normal, // normal is the default
    ),
 );

Creating FloatingBubbles.alwaysRepeating() (Creates Floating Bubbles that always floats and doesn't stop.)

return Stack(
   children: [
    Positioned.fill(
       child: Container(
       color: Colors.red,
     ),
    ),
    Positioned.fill(
        child: FloatingBubbles.alwaysRepeating(
        noOfBubbles: 25,
         colorsOfBubbles: [
            Colors.green.withAlpha(30),
            Colors.red,
         ],
        sizeFactor: 0.16,
        opacity: 70,
        paintingStyle: PaintingStyle.fill,
        shape: BubbleShape.square,
        speed: BubbleSpeed.normal,

   ),
);
