  <p>Hello, I'm using FadeInImage with a placeholder and an image, but the second image do not cover the complete parent, I'm using fit:BoxFit.cover but any way the result is not good. Anyone knows how to make it possible. This is my actual code. The 'document[_newsImage] is an URL took from CloudFirebase.</p>

          child: new Card(
