Create a widget for Annotation view for example

class AnnotationView extends StatelessWidget {
const AnnotationView({
Key? key,
required this.annotation,
}) : super(key: key);

final Annotation annotation;

@override
Widget build(BuildContext context) {
return Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(5),
color: Colors.white,
),
child: Row(
children: [
Expanded(
child: Container(
decoration: const BoxDecoration(
borderRadius: BorderRadius.only(
topLeft: Radius.circular(5),
bottomLeft: Radius.circular(5),
),
),
child: typeFactory(annotation.type),
),
),
Expanded(
flex: 2,
child: Padding(
padding: const EdgeInsets.all(4.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text(
annotation.type.toString().substring(15),
maxLines: 1,
style: const TextStyle(fontWeight: FontWeight.bold),
),
Text(
'${annotation.distanceFromUser.toInt()} m',
),
],
),
),
)
],
),
);
}

Widget typeFactory(AnnotationType type) {
IconData iconData = Icons.ac_unit_outlined;
Color color = Colors.teal;
switch (type) {
case AnnotationType.pharmacy:
iconData = Icons.local_pharmacy_outlined;
color = Colors.red;
break;
case AnnotationType.hotel:
iconData = Icons.hotel_outlined;
