corner_bouncer #

A simple Flutter widget that bounces around the boundaries of its container, ala that classic DVD menu icon.

Getting Started #

To use the CornerBouncer widget in your Flutter project, you need only wrap it in a LayoutBuilder and then a Stack. These are excellent for adding a little life to a Scaffold background, or for programming a Pong client.

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Corner Bouncer Demo',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Corner Bouncer'),
        body: LayoutBuilder(
          builder: (BuildContext context, BoxConstraints constraints) {
            return Stack(
              children: <Widget>[
                  child: FlutterLogo(
                    size: 100,
                  childHeight: 100,
                  childWidth: 100,
                  containerWidth: constraints.maxWidth,
                  containerHeight: constraints.maxHeight,

[0.0.1] - 2019-04-29
