Bubble Picker

A customizable and interactive bubble picker widget for Flutter. This widget displays a collection of bubbles that are attracted to a central point while repelling each other. Users can interact with the bubbles by tapping or dragging them around.

Table of Contents

Features

  • Interactive Bubbles: Bubbles can be dragged, tapped, and will respond to user interactions.
  • Customizable Appearance: Customize the color, size, image, and gradient of each bubble.
  • Dynamic Animations: Bubbles smoothly animate towards a central point and repel each other.
  • Flexible Configuration: Define bubbles with child widgets, images, and custom behaviors.

Usage

Import the BubblePicker widget into your Dart file:

  import 'package:bubble_picker/bubble_picker.dart';

Create a BubblePicker widget:

BubblePicker(
  size: Size(400, 800),
  bubbles: [
    BubbleData(
      color: Colors.blue,
      radius: 0.1,
      child: Icon(Icons.star, color: Colors.white),
    ),
    BubbleData(
      imageProvider: AssetImage('assets/images/bubble.png'),
      radius: 0.15,
    ),
    // Add more bubbles here
  ],
)

Example

Import the BubblePicker widget into your Dart file:

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

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Bubble Picker Example'),
        ),
        body: Center(
          child: BubblePicker(
            size: Size(400, 800),
            bubbles: [
              BubbleData(
                color: Colors.red,
                radius: 0.1,
                child: Text('A'),
              ),
              BubbleData(
                imageProvider: AssetImage('assets/bubble_image.png'),
              ),
              BubbleData(

                color: Colors.red.withOpacity(0.3),
                radius: 0.2,

                  ],
                  begin: Alignment.topLeft,
                  end: Alignment.bottomRight,
                ),
              ),
              // Add more bubbles here
