Inserting new Widgets as List on Pressing Button in Flutter
I am making a screen like this which could select contacts from the phone book and insert the names as lists in my application. I want is that when I press Add caregiver(+) button it should select a contact and show the name. I made a Widget for the MOM part but whenever I click the button it rewrites the MOM to any contact that I select from the phone book.
I made this screen:
I also want to add Dad and Sister's Contact in the same manner as mom, but I am unable to do it
This is my code for the screen:
import 'package:epicare/NavigBar.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:flutter_switch/flutter_switch.dart';
import 'package:permission_handler/permission_handler.dart';
import 'package:contact_picker/contact_picker.dart';
//Check contacts permission
Future<PermissionStatus> _getPermission() async {
final PermissionStatus permission = await Permission.contacts.status;
if (permission != PermissionStatus.granted &&
permission != PermissionStatus.denied) {
final Map<Permission, PermissionStatus> permissionStatus =
await [Permission.contacts].request();
return permissionStatus[Permission.contacts] ??
PermissionStatus.undetermined;
} else {
return permission;
}
}

@override
_CaregiverScreenState createState() => _CaregiverScreenState();

Please help me out as i am new to Flutter. Thank you in advance :)
Solution
You need to manage Caregiverlist you've selected from contacts. for example
class Caregiver {
String name;
bool isActive;
Caregiver({this.name, this.isActive});
factory Caregiver.fromJson(Map<String, dynamic> map) {
if (map == null) return null;
return Caregiver(name: map['name'] ?? "",
isActive: map['isActive']);
}
}
initialize caregiver list
List<Caregiver> _careList = [];add Caregiver
Contact contact = await _contactPicker.selectContact(); setState(() { _careList.add(Caregiver(name: contact, isActive: true)); });show Caregiver list (To show ListView inside of Scrollview, add the following 3 lines.
ListView.separated( physics: NeverScrollableScrollPhysics(), shrinkWrap: true, primary: false, itemBuilder: (context, index) { return _caregiverWidget(index); }, separatorBuilder: (_, __) => Divider(), itemCount: _careList.length);Add new function
Widget _caregiverWidget(int index) { Caregiver _caregiver = _careList[index]; print(_caregiver.name); var c = _caregiver.name.split(' '); print(c[0]); var caregiver = c[0]; var output = getInitials(string: caregiver, limitTo: 1); print(output); // var i = caregiver.codeUnitAt(0); // print(i); return Container( padding: EdgeInsets.symmetric(vertical: 20, horizontal: 27), child: Row( //crossAxisAlignment: CrossAxisAlignment.center, //mainAxisAlignment: MainAxisAlignment.spaceBetween, children: <Widget>[ CircleAvatar( radius: 24, backgroundColor: const Color(0xffd4d411), child: CircleAvatar( radius: 22, backgroundColor: Colors.white, child: Text( output, style: TextStyle( fontFamily: 'Segoe UI', fontSize: 20, color: const Color(0xff000000), ), ), ), ), SizedBox(width: 19), Column( crossAxisAlignment: CrossAxisAlignment.start, children: [ Text( caregiver, style: TextStyle( fontFamily: 'Montserrat', fontSize: 13, color: const Color(0xff000000), height: 1.5384615384615385, fontWeight: FontWeight.w600), textHeightBehavior: TextHeightBehavior(applyHeightToFirstAscent: false), textAlign: TextAlign.left, ), _caregiver.isActive ?
