Flutter column doesn't expand

Question

I am a complete newbie in Flutter, but I already like it. The question is: why is the column not expanding to the full height?

code is on gist.github

A Column widget is flexible - it will try to take up as much space as it needs but no more. If you want it to take up all availible space, then wrap it in an Expanded widget.

createChildren() {   return [     Image.network(       testImg,       height: imageSize,       width: imageSize,     ),     Padding(padding: EdgeInsets.only(left: 16.0)),     Expanded(child:       Column(         crossAxisAlignment: CrossAxisAlignment.start,         mainAxisAlignment: MainAxisAlignment.spaceBetween,         children: [           boldText("Some title"),           Text("Address"),           Text("Description")         ],       ),     ),   ]; }
