Flutter/Firebase/url_launcher/ how to send SMS message from the app?

I am developing a mobile app with Flutter.

I am just wondering how to send an SMS message from the app.

NewCustomIconButton(
  text: 'SMS',
  icon: Icons.sms,
  onPressed: () async {
    await Clipboard.setData(ClipboardData(
        text:
            "Hello, ${confirmedBooking.userAccountID},  you have booking with ${_artistAccount.getFullname()}, "));
    UrlLauncher.launch(
        "sms://${confirmedBooking.phoneNumber}");
    },
  ),
)

In this code, if I press the button, it goes SMS screen on my phone, however, I am just wondering if it is possible that sending an SMS message without manually typing the text.

Thanks for reading,

I am waiting for your help.

If you'd like to send an SMS directly from the code, you could use the sms package:

NB: the sms package supports only Android as for now

import 'package:sms/sms.dart';

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

If you'd like to open a new SMS message prefilled with specified content and recipient, you could do so by launching the following URI: sms://${confirmedBooking.phoneNumber}?body=${messageBody}

Remember to encode the String to get a valid URI:

String uriAndroid = "sms:${confirmedBooking.phoneNumber}?body=${messageBody}";
String uriIOS = "sms:${confirmedBooking.phoneNumber}&body=${messageBody}";
uriAndroid = Uri.encodeFull(uriAndroid);
uriIOS = Uri.encodeFull(uriIOS); // valid URIs

For reference, follows a full code snippet according to your specific scenario:

NewCustomIconButton(
     text: 'SMS',
     icon: Icons.sms,
     onPressed: () async {
       String smsContent = 
               "Hello, ${confirmedBooking.userAccountID},  you have booking with ${_artistAccount.getFullname()}";
       await Clipboard.setData(ClipboardData(
           text: smsContent));
       String char = Platform.isAndroid ? '?' : '&';
       UrlLauncher.launch(
           Uri.encodeFull("sms:${phoneNumber}${char}body=${smsContent}"));
     },
   ),
)

I'd also suggest to create a reusable function:

void createNewSms(String phoneNumber, String smsContent) {
 String char = Platform.isAndroid ? '?' : '&';
 UrlLauncher.launch(
     Uri.encodeFull("sms:${phoneNumber}${char}body=${smsContent}"));
}
