How to Send, Read and Delete SMS in flutter?

yes there is library available for this

Sending SMS

import 'package:sms/sms.dart';

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

Receiving SMS

import 'package:sms/sms.dart';

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

Deleting SMS

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

this answer as your comment (for listening incoming SMS ).

Getting all SMS messages #

import 'package:sms/sms.dart';

void main() {
  SmsQuery query = new SmsQuery();
  List<SmsMessage> messages = await query.getAllSms;

}

This list (messages) return all sms.

The above 'package:sms/sms.dart' is no longer up to date. You can use the telephony package instead.

For example, sending an SMS:
Import the telephony package:

import 'package:telephony/telephony.dart';

Retrieve the singleton instance of telephony by calling:

final Telephony telephony = Telephony.instance;

Add the following permission in your AndroidManifest.xml:

<uses-permission android:name="android.permission.SEND_SMS"/>

And then, to send the SMS directly from your app:

telephony.sendSms(
    to: "1234567890",
    message: "May the force be with you!"
);

In the above documentation, they tell you how to also read SMS messages and more (didn't see how to delete though).
