FLUTTER：如何为投票应用堆叠图像

Question

I am doing a voting app and I have a problem, I want to stack images as many time there is votes(1 stack per vote). This is a picture of what I want to do. I tried to use Listview like this

ListView(
  children: <Widget>[
    Image(
      image: AssetImage('assets/images/results/green.png'),
    ),
    Image(
      image: AssetImage('assets/images/results/green.png'),
    ),
  ],
),

The problem is that there is so much space between the 2 images. Can you help me?

Answer 1

Try to wrap the image with:

Align(
  alignment: Alignment.topLeft,
  heightFactor: 0.94/*change this value until you are satisfied (between 0 and 1)*/,
  child: //your image
),
