Answer 1

You can edit the line
fit: BoxFit.cover
to
fit: BoxFit.fitHeight
inside you container that grabs image from network.

Answer 2

I think you are trying to put a list inside another list, so the error shows
you can put the list (nested list which is inside the list) in a container and specify a height :
ListView _buildMainView(){
return new ListView(
children: <Widget>[
new Text("Main List"),
new Container(
height: 100.0,
child: new ListView(
children: <Widget>[
new Text("Nested List")
],
),
)
],
);
)

Answer 3

If you have a ListView with vertical scroll direction, and want it to have a infinity height, maybe you don't need a ListView.
You can use a regular Column.
