sms_advanced

This is an SMS library for Flutter.

Getting Started

Installation and Usage

Once you're familiar with Flutter you may install this package adding sms_advanced (1.0.1 or higher) to the dependencies list of the pubspec.yaml file as follow:

...
dependencies:
  flutter:
    sdk: flutter

  sms_advanced: ^1.0.1
...

Then run the command flutter packages get on the console.

Querying SMS messages

Add the import statement for sms_advanced and create an instance of the SmsQuery class:

import 'package:sms_advanced/sms_advanced.dart';

void main() {
  SmsQuery query = new SmsQuery();
}

Getting all SMS messages

List<SmsMessage> messages = await query.getAllSms;

Note: the use of await keyword means that getAllSms is resolved asynchronously and a Future is retorned. To use await, you must be in a function marked async.

Filtering SMS messages

The method querySms from the SmsQuery class returns a list of filtered SMS messages that match the supplied parameters. For example, for querying all the SMS messages sent and received, you could this code:

await query.querySms({
    kinds: [SmsQueryKind.Inbox, SmsQueryKind.Sent]
});

You can also query all the SMS messages sent and received from a specific contact:

await query.querySms({
    address: getContactAddress()
});

Getting all Threads Conversations

With SmsQuery you can also get the entire list of conversations:

List<SmsThread> threads = await query.getAllThreads;

extract information

List<SmsThread> threads = await query.getAllThreads;
  for( var index = num ; index >= threads.length; index-- ) { 
       String sendernumber = threads[index].contact?.address;
       String sim = threads[index].messages.first.sim.toString();
       String message = threads[index].messages.first.body;
       print('sender number: $sendernumber');
       print('reciever sim: $sim');
       print('message: $message');
   }

Getting the Contact info

Each conversation thread is related with a Contact. The class Contact contains all the info of a thread contact (address, photo, full name). To get access to Contact class you must import 'package:sms_advanced/contact.dart' into your dart file:

import 'package:sms_advanced/contact.dart';

void main() {
  ...
  Contact contact = threads.first.contact;
  print(contact.address);
}

Querying Contact

You can also query a contact by its address (phone number):

import 'package:sms_advanced/contact.dart';

void main() {
  ContactQuery contacts = new ContactQuery();
  Contact contact = await contacts.queryContact(someAddress());
  print(contact.fullName);
}
String getAddress() { return someRandomAddress; }

The Contact photo

You can retrieve the photo of the contact (full size or thumbnail):

...
Uint8List fullSize = contact.photo.bytes;
Uint8List thumbnail = contact.thumbnail.bytes;

User Profile

Some times it is useful to request basic info of the phone owner, like the contact photo, addresses, etc.

import 'package:sms_advanced/contact.dart';

UserProfileProvider provider = new UserProfileProvider();
UserProfile profile = await provider.getUserProfile();
print(profile.fullName);

Sending SMS

What about sending a SMS? All you have to do is to create an instance of the SmsSender class:

import 'package:sms_advanced/sms_advanced.dart';

void main() {
  SmsSender sender = new SmsSender();
  String address = someAddress();
  ...
  sender.sendSms(new SmsMessage(address, 'Hello flutter world!'));
}

To be notified when the message is sent and/or delivered, you must add a listener to your message:

import 'package:sms_advanced/sms_advanced.dart';

void main() {
  SmsSender sender = new SmsSender();
  String address = someAddress();
  ...
  SmsMessage message = new SmsMessage(address, 'Hello flutter world!');
  message.onStateChanged.listen((state) {
    if (state == SmsMessageState.Sent) {
      print("SMS is sent!");
    } else if (state == SmsMessageState.Delivered) {
      print("SMS is delivered!");
    }
  });
  sender.sendSms(message);
}

Some times it is useful to be notified of delivered messages regardless of the message. To do that you must subscribe to the onSmsDelivered of the SmsSender class instance:

void main() {
...
SmsSender sender = new SmsSender();
sender.onSmsDelivered.listen((SmsMessage message){
  print('${message.address} received your message.');
}));
}

You can also send with another SimCard:

void main() {
SimCardsProvider provider = new SimCardsProvider();
SimCard card = await provider.getSimCards()[0];
SmsSender sender = new SmsSender();
SmsMessage message = new SmsMessage("address", "message");
sender.sendSMS(message, simCard: card);
}

Note: Using the onSmsDelivered from the SmsSender will only notify to listeners of messages that has been sent through SmsSender.send().

Receiving SMS

If you want to be notified for incoming new messages you must subscribe to an instance of the SmsReceiver class:

import 'package:sms_advanced/sms_advanced.dart';

void main() {
  SmsReceiver receiver = new SmsReceiver();
  receiver.onSmsReceived.listen((SmsMessage msg) => print(msg.body));
}

Deleting SMS

Only deleting one by one is available. Don't forget to make your sms app the default sms app. blogpost guide

import 'package:sms_advanced/sms_advanced.dart';

void main() {
SmsRemover smsRemover = SmsRemover();
<boolean value> = await smsRemover.removeSmsById(sms.id, _smsThread.threadId);
}

Android Integration

Activity Changes

Note that sms_advanced requires the use of a FragmentActivity instead of an Activity. To update your application:

If you are using FlutterActivity directly, change it to FlutterFragmentActivity in your AndroidManifest.xml.

If you are using a custom activity, update your MainActivity.java:

import io.flutter.embedding.android.FlutterFragmentActivity;

public class MainActivity extends FlutterFragmentActivity {
    // ...
}

or MainActivity.kt:

import io.flutter.embedding.android.FlutterFragmentActivity

class MainActivity: FlutterFragmentActivity() {
    // ...
}

to inherit from FlutterFragmentActivity.
