DecorationImage doesn't show the image - Flutter

Question

I couldn't find anything related to this, so I guess I am doing something very wrong. I am trying to display a DecorationImage inside BoxDecoration, but nothing shows on my screen at all.

I try to show the related asset with Image.asset('assets\\test.png'); and that works with no problem. I have tried to put things like AssetImage or FileImage inside DecorationImage, but it seems like none of them work for me.

My code is basically as below:

    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
    body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            new Container(
              decoration: new BoxDecoration(
                image: new DecorationImage(
                  image: new AssetImage('assets\\test.png'),
                  fit: BoxFit.cover,
                ),
              ),
            ),
          ],
        ),
      )
   );

What should I do for my test.png to show? Currently I just see an empty screen.

You need to give width and height to your Container, like this

new Container(
  height: 100,
  width: 100,
  decoration: new BoxDecoration(
    image: new DecorationImage(
      image: new AssetImage('assets\\test.png'),
      fit: BoxFit.cover,
    ),
  ),
),
