title: Flutter: add a floating action button to an image
body: <p>I'm trying to add a floating action button to an image. The button will be used to change the selected image. I want the button to float over the bottom right of the image. So far all I can do is add the floating action button directly below the image. Thanks for any help!</p>
  
  <pre><code>@override
  Widget build(BuildContext context) {
  
    // Create the view scaffold. Use a list view so things scroll.
    return new Scaffold(
      appBar: new AppBar(
        title: new Text("My Title"),
      ),
      body: new ListView(
        children: [
          new Container(
            padding: EdgeInsets.zero,
            child: new Image.asset(
              "assets/images/background_image.png",
              fit: BoxFit.fitWidth,
            ),
          ),
          new FloatingActionButton(
            child: const Icon(Icons.camera_alt),
            backgroundColor: Colors.green.shade800,
            onPressed: () {},
          ),
          new Divider(),
          new ListTile(
            title: new Text('Email'),
            leading: const Icon(Icons.email),
            onTap: () {},
          ),
          new Divider(),
        ],
      ),
    );
  }
  </code></pre>
