This is a custom widget that calls the contact list from the phone and you can setup actions for a user that constains on the users collection and other if don't contains.
First create a custom widget called ContactListNew

class ContactListNew extends StatefulWidget {
const ContactListNew({

this.callBackActionNoContain,
}) : super(key: key);
final double? width;
final double? height;
final Future<dynamic> Function()? callBackAction;
final List<UsersRecord>? usersList;
final Future<dynamic> Function()? callBackActionNoContain;
@override
_ContactListNewState createState() => _ContactListNewState();
}
class _ContactListNewState extends State<ContactListNew> {
late List<Contact> _contacts;
bool _permissionDenied = false;
bool _loading = false;
@override
void initState() {
super.initState();
_checkAndRequestPermission();
}
Future<void> _checkAndRequestPermission() async {
final newStatus = await Permission.contacts.request();
if (newStatus.isGranted) {
_loadContacts();
} else {
setState(() {
_permissionDenied = true;
});
}
}
Future<void> _loadContacts() async {
setState(() {
_loading = true;
});
Iterable<Contact> contacts = await ContactsService.getContacts();
setState(() {
_contacts = contacts.toList();
// Sort the contacts list to show contacts in the usersList first
_contacts.sort((a, b) {
String aPhoneNumber = a.phones!.isNotEmpty
? a.phones!.first.value ?? ''
: 'No phone number';
String bPhoneNumber = b.phones!.isNotEmpty
? b.phones!.first.value ?? ''
: 'No phone number';
bool aIsInUserList =
widget.usersList?.any((user) => user.phoneNumber == aPhoneNumber) ??
false;
bool bIsInUserList =
widget.usersList?.any((user) => user.phoneNumber == bPhoneNumber) ??
false;
if (aIsInUserList && !bIsInUserList) {
return -1;
} else if (!aIsInUserList && bIsInUserList) {
return 1;
} else {
return 0;
}
});
_loading = false;
});
}
@override
Widget build(BuildContext context) {
return Container(
width: widget.width,
height: widget.height,
child: _permissionDenied
? Center(
child: ElevatedButton(
onPressed: _checkAndRequestPermission,
child: Text('Allow access to contacts'),
),
)
: _loading
? Center(child: CircularProgressIndicator())
: ListView.builder(
itemCount: _contacts.length,
itemBuilder: (BuildContext context, int index) {
final contact = _contacts[index];
String phoneNumber = contact.phones!.isNotEmpty
? contact.phones!.first.value ?? ''
: 'No phone number';
// Check if the contact is in the userList
final isInUserList = widget.usersList
?.any((user) => user.phoneNumber == phoneNumber) ??
false;
return ListTile(
leading:
(contact.avatar != null && contact.avatar!.isNotEmpty)
? CircleAvatar(
backgroundImage: MemoryImage(contact.avatar!),
)
: CircleAvatar(
child: Text(contact.initials()),
),
title: Text(contact.displayName ?? 'Unknown'),
subtitle: Text(phoneNumber),
trailing: isInUserList
? Icon(Icons.circle_sharp,
color: FlutterFlowTheme.of(context).primary)
: null, // Add a trailing icon if the contact is in the userList
onTap: () {
// Set the PhoneNumber in the FFAppState
FFAppState().PhoneNumber = phoneNumber;
if (isInUserList) {
if (widget.callBackAction != null) {
widget.callBackAction!.call();
}
} else {
if (widget.callBackActionNoContain != null) {
widget.callBackActionNoContain!.call();
}
}
},
);
},
),
);
}
}Setup the dependencies
contacts_service: ^0.6.3
permission_handler: ^10.2.0
Create the parameters:
You will need to create an Local Variable to save the phone number before the action:
Check the spelling PhoneNumber as String
Now add the widget where you want to show the list and setup a query to call all users from users collection;
On the widget properties choose the query document list:
And for the actions you can choose whatever you want to do.
I choose for now that if the contact is on the users collection it will call to him, if not will call a share action to send to whoever you want.
When the contact is on the users list you call the number from the APP STATE PhoneNumber
When does not contains it will share a simple text.
Dont forget to add the permission to access contacts
On the list of contacts, Will show a circle icon on the right of the contact if the contact is on the users collection, and is ordering first the contacts that are on the collection.
Hope this will help! any questions please DM me 🤩
