and I want to build view using lines and places. So if group have 2 lines and each line has 15 places I want to build something like that:
...............
...............
This is my code:
import 'package:flutter/material.dart';
import 'package:parking/models/groups.dart';
import 'package:parking/models/parking_group.dart';
import 'package:parking/services/parking_service.dart';
class ParkingDetailsScreen extends StatefulWidget {
@override
createState() => ParkingDetailsState();
}
class ParkingDetailsState extends State<ParkingDetailsScreen> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Parking Details"),
),
body: FutureBuilder<ParkingGroup>(
future: ParkingService.getParking(),
builder: (context, snapshot) {
if (snapshot.hasError) print(snapshot.error);
return snapshot.hasData
? _buildParking(snapshot.data)
: Center(child: CircularProgressIndicator());
},
)
);
}
}
final _parkings = <Groups>[];
Widget _buildParking(ParkingGroup parkingGroup) {
_parkings.clear();
_parkings.addAll(parkingGroup.groups);
return ListView.builder(
itemCount: _parkings.length,
itemBuilder: (context, index) {
return _buildRow(_parkings[index], context);
},
);
}
Widget _buildRow(Groups parkingGroup, BuildContext context) {
return Container(
padding: const EdgeInsets.all(16.0),
child: Row(
children: _buildRowList(parkingGroup),
),
);
}
List<Widget> _buildRowList(Groups parkingGroup) {
List<Widget> places = [];
for (var place in parkingGroup.lines) {
for (var placeLine in place.places) {
places.add(_buildPlace(placeLine));
}
}
return places;
}
Widget _buildPlace(place) {
return Container(
padding: const EdgeInsets.only(bottom: 8.0),
child:
SizedBox(
height: 5,
width: 5,
child: DecoratedBox(
decoration: BoxDecoration(
border: Border.all(color: Colors.blueAccent),
)),
),
);
}
//
//Widget _buildRow(Groups parkingGroup, BuildContext context) {
// return Container(
// padding: const EdgeInsets.all(16.0),
// child: Row(
// children: [
// Container(
// padding: const EdgeInsets.only(bottom: 8.0),
// child:
// SizedBox(
// height: 30,
// width: 30,
// child: DecoratedBox(
// decoration: BoxDecoration(
// border: Border.all(color: Colors.blueAccent),
// )),
// ),
// ),
// ],
// ),
// );
//}
but for this code I see all places in one line:
..............................
instead of
...............
...............
What I need to change in my code to get good result?

You need to change your _buildRow() and _buildRowList() methods:
Widget _buildRow(Groups parkingGroup, BuildContext context) {
return Container(
padding: const EdgeInsets.all(16.0),
child: Column( // As you expect multiple lines you need a column not a row
children: _buildRowList(parkingGroup),
),
);
}
List<Widget> _buildRowList(Groups parkingGroup) {
List<Widget> lines = []; // this will hold Rows according to available lines
for (var line in parkingGroup.lines) {
List<Widget> placesForLine = [] // this will hold the places for each line
for (var placeLine in line.places) {
placesForLine.add(_buildPlace(placeLine));
}
lines.add(Row(children: placesForLine));
}
return lines;
}
