how to get mobile messages using flutter - flutter

Question

I have to get messages from mobile so I am using this plugin. It is working but I get no messages, just printing the result Instance of 'SmsMessage' in the console, but I did everything specified in document example. did I make any mistakes?
source code
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:sms/sms.dart';
class MessagesScreen extends StatefulWidget {
MessagesScreen({Key key}) : super(key: key);
#override
_MessagesScreenState createState() => _MessagesScreenState();
}
class _MessagesScreenState extends State<MessagesScreen> {
List _allMessages;
#override
void initState() {
super.initState();
getAllMessages();
}
Future getAllMessages() async {
SmsQuery query = new SmsQuery();
List<SmsMessage> messages = await query.getAllSms;
debugPrint("Total Messages : " + messages.length.toString());
print(messages);
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Messages"),
),
body: ListView.builder(
itemCount: 1,
itemBuilder: (BuildContext context, int index) {
return Text("Test");
},
),
);
}
}

Answer 1

This has nothing to do with SMS messages, you just cannot print a list of custom objects that way.
Go through the list in a loop and print the property of every message that you want to print. Just like you would have to do with any other complex object.

Answer 2

The behavior you describe is actually normal. The messages will be returned as an instance of the SmsMessage class.
When you try to print an object, it is converted to a string. By default the toString method will display Instance of "Class name"; and in your case, that's why you are having that output, you are trying to print a list of objects.
If for each of the messages, you would like to display the body, this code snippet should help you:
Future getAllMessages() async {
SmsQuery query = new SmsQuery();
List<SmsMessage> messages = await query.getAllSms;
debugPrint("Total Messages : " + messages.length.toString());
messages.forEach((element) { print(element.body); });
}
