How to specify ListTile height in Flutter - flutter

Question

In this code, I am trying to make a list of buttons or tiles "as buttons do not work well for me " at the very top of the page. Thus, when one is clicked it returns a value in the rest of the page.
The issue is The tile here toke around more than half of the page which makes it looks inconsistent. I want to limit the height of the tile, I have tried putting them in a row and a container and it doesn't work. Any HELP will be appreciated.
the result after running the code is:
this is the error after runing the code :
class HomePage extends StatefulWidget {
// const HomePage({Key key}) : super(key: key);
#override
HomePageState createState() {
return new HomePageState();
}
}
class HomePageState extends State<HomePage> {
List<String> temp=new List();
List<String> temp1=['Nile University', 'Smart Village', 'Zewail'];
Map<String,String> map1={};
#override
void initState() {
super.initState();
getplaces(temp);
getuser(map1,'1jKpg81YCO5PoFOa2wWR');
}
Future<List> getuser(temp,String place) async{
List<String> userids=[];
QuerySnapshot usersubs= await Firestore.instance.collection('tempSubs').getDocuments();
QuerySnapshot userid= await Firestore.instance.collection('users').where('place',isEqualTo: place).getDocuments();
userid.documents.forEach((DocumentSnapshot doc,){
usersubs.documents.forEach((DocumentSnapshot doc1){
if(doc.documentID==doc1.documentID){
doc1.data['products'].forEach((k,v){
if( DateTime.fromMillisecondsSinceEpoch(v).day==DateTime.now().day){
int x= DateTime.fromMillisecondsSinceEpoch(v).day;
print('keey equal $k and v is $x');
print('dy is $x');
userids.add(
doc.documentID);
}
});
}
} ); }
);
print('doc.documentID');
print (userids);
setState(() {});
return userids;
}
Future<List> getplaces(temp) async{
QuerySnapshot place= await Firestore.instance.collection('places').getDocuments();
place.documents.forEach((DocumentSnapshot doc){
temp.add(
doc.data['name']
);
// print(doc.data['name']);
});
// print(temp);
setState(() {});
return temp;
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Home Page"),
),
body: !temp.isNotEmpty?
CircularProgressIndicator():
Row(mainAxisSize:MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceAround,
children:<Widget>[
Container(
height: 100.0,
child:
ListView.builder(
scrollDirection: Axis.horizontal,
itemExtent: 100.0,
itemCount:temp.length,
itemBuilder:(BuildContext context, int index) {
return ListTile(title: Text(temp[index]),onTap:
(){
print(temp[index]);
}
);}
),),
Container(child:Text('data'),)
],),
);
}
}

Applying VisualDensity allows you to expand or contract the height of list tile. VisualDensity is compactness of UI elements. Here is an example:
// negative value to contract
ListTile(
title: Text('Tile title'),
dense: true,
visualDensity: VisualDensity(vertical: -3), // to compact
onTap: () {
// tap actions
},
)
// positive value to expand
ListTile(
title: Text('Tile title'),
dense: true,
visualDensity: VisualDensity(vertical: 3), // to expand
onTap: () {
// tap actions
},
)
The values ranges from -4 to 4 and default is 0 as of writing this answer.
However, you cannot use this method for specific width or height size.

Answer 2

Just remove the Expanded Widget to avoid fill the space available and use a parent Container with a fixed height, the same as the itemExtent value:
Column(
children: <Widget>[
Container(
height: 100.0,
child: ListView.builder(
scrollDirection: Axis.horizontal,
itemExtent: 100.0,
itemCount: temp.length,
itemBuilder: (BuildContext context, int index) {
return ListTile(
title: Text(temp[index]),
onTap: () {
print(temp[index]);
});
}),
),
Container(
child: Text('data'),
)
],
),

You should use a Container or Padding instead of ListTile if you need more customization.
You cannot set the height, but you can make it smaller by setting the dense property to true:
ListView.builder(
scrollDirection: Axis.vertical,
shrinkWrap: true,
itemCount: list.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(list[index].name,style: TextStyle(fontSize: 20.0),),
contentPadding: EdgeInsets.symmetric(vertical: 0.0, horizontal: 16.0),
dense:true,
);
},
);
ListTile:
A single fixed-height row that typically contains some text as well as
a leading or trailing icon.
To be accessible, tappable leading and trailing widgets have to be at
least 48x48 in size. However, to adhere to the Material spec, trailing
and leading widgets in one-line ListTiles should visually be at most
32 (dense: true) or 40 (dense: false) in height, which may conflict
with the accessibility requirement.
For this reason, a one-line ListTile allows the height of leading and
trailing widgets to be constrained by the height of the ListTile. This
allows for the creation of tappable leading and trailing widgets that
are large enough, but it is up to the developer to ensure that their
widgets follow the Material spec.

Since there's no height property in ListTile you can limit the size of a tile by placing it inside a SizedBox:
SizedBox(
height: 32,
child: ListTile(..))
