I am Creating a delivery app in which if the delivery is 2 km far it will show the order to the driver but I don't know why it is giving error.
This error is most probably caused by StreamBuilder. This is made using Flutter. I have used Firebase-Firestore as my data base.
My Code:
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';
import 'package:geocoding/geocoding.dart';
import 'package:geolocator/geolocator.dart';
import 'package:homekitchen_delivery_app_new/globals.dart';
import 'package:homekitchen_delivery_app_new/models/DriversRequest.dart';
class DemoNearMe extends StatefulWidget {
const DemoNearMe({super.key});
@override
State<DemoNearMe> createState() => _DemoNearMeState();
}
class _DemoNearMeState extends State<DemoNearMe> {
Placemark? placemark;
List positions = [];
Position? position;
List<Placemark>? placemarks;
getCurrentLocation() async {
await Geolocator.requestPermission().whenComplete(() async {
Position newPos = await Geolocator.getCurrentPosition(
desiredAccuracy: LocationAccuracy.high);
position = newPos;
placemarks = await placemarkFromCoordinates(
position!.latitude, position!.longitude);
Placemark pMark = placemarks![0];
placemark = pMark;
});
return [placemark, position!.latitude, position!.longitude];
}
@override
void initState() {
WidgetsBinding.instance.addPostFrameCallback((_) async {
positions = await getCurrentLocation();
});
super.initState();
}
@override
Widget build(BuildContext context) {
return Scaffold(

.snapshots(),

if (snapshot.connectionState == ConnectionState.waiting) {
return Center(child: CircularProgressIndicator());
}
return snapshot.hasData
? ListView.builder(
shrinkWrap: true,
itemCount: snapshot.data!.docs.length,
itemBuilder: (context, index) {
final data = snapshot.data!.docs[index].data();
DriverRequest driverRequest =
DriverRequest.fromJson(data as Map<String, dynamic>);
double distanceBetween = Geolocator.distanceBetween(
positions[1],
positions[2],
driverRequest.sellerLat,
driverRequest.sellerLng) /
1000;
if (distanceBetween <= 2) {
return Padding(
padding: const EdgeInsets.all(20.0),

}

}),

}
}

════════ Exception caught by rendering library ═════════════════════════════════
The following assertion was thrown during performLayout():
RenderCustomMultiChildLayoutBox object was given an infinite size during layout.
This probably means that it is a render object that tries to be as big as possible, but it was put inside another render object that allows its children to pick their own size.
The nearest ancestor providing an unbounded height constraint is: _RenderSingleChildViewport#b1d96 relayoutBoundary=up10 NEEDS-LAYOUT NEEDS-COMPOSITING-BITS-UPDATE
The constraints that applied to the RenderCustomMultiChildLayoutBox were: BoxConstraints(0.0<=w<=392.7, 0.0<=h<=Infinity)
The exact size it was given was: Size(392.7, Infinity)
See https://flutter.dev/docs/development/ui/layout/box-constraints for more information.

Wrap the ListView.builder with an Expanded widget. This will make the ListView take up as much space as available, with no overflowing.
Also, when at all possible, try not to use shrinkWrap: true. it is terrible for performance, because it has to calculate the size of the scroll view every time the scroll position changes.
