Problem to send email with URL launcher in flutter

Question

Hello I try to launch email page with recipent. I tried flutter email sender who work with android but not on ios for me. So I tried url launcher to do the same thing, but not working also with iOS. I use iOS simulator, the problem can be this ?

I use this example of url launcher

mailto:xxxxx@xxxxx.com?subject=News&body=New%20plugin

I have this error

[VERBOSE-2:ui_dart_state.cc(148)] Unhandled Exception: Could not launch mailto:xxxx@xxxx.com?subject=News&body=New%20plugin
#0      _menuscreenState._launchURL (package:xxxx/bottom.dart:8285:7)
<asynchronous suspension>
#1      _menuscreenState.build.<anonymous closure>.<anonymous closure> (package:xxxx/bottom.dart:8705:13)

Here is the full example with url launcher

import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {


  String email="contact@ouiquit.com";
  _launchEmail() async {
    if (await canLaunch("mailto:$email")) {
      await launch("mailto:$email");
    } else {
      throw 'Could not launch';
    }
  }

  @override
  Widget build(BuildContext context) {


    return MaterialApp(
      theme: ThemeData(primaryColor: Colors.red),
      home: Scaffold(
        appBar: AppBar(
          title: Text('test mail'),
          actions: <Widget>[
            IconButton(
              onPressed: _launchEmail,
              icon: Icon(Icons.send),
            )
          ],
        ),


      ),
    );
  }


}

Here is the error

[VERBOSE-2:ui_dart_state.cc(148)] Unhandled Exception: MissingPluginException(No implementation found for method canLaunch on channel plugins.flutter.io/url_launcher)

This works for me on both Android and iOS devices:

Add query parameter if you have subject and body too.

final Uri params = Uri(
  scheme: 'mailto',
  path: 'email@example.com',
  query: 'subject=App Feedback&body=App Version 3.23', //add subject and body here
);

var url = params.toString();
if (await canLaunch(url)) {
  await launch(url);
} else {
  throw 'Could not launch $url';
}

The above given solutions will work for API < 30 but for API >= 30 the following is needed to be added to your AndroidManifest.xml file for email sending to work.

<queries>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="https" />
    </intent>
    <intent>
        <action android:name="android.intent.action.SEND" />
        <data android:mimeType="*/*" />
    </intent>
</queries>

For iOS

There is no Email App installed on the iOS Simulator you only can test this on a real device.

This is the function I use to send mail using url_launcher :

void _launchURL() async {
    final Uri params = Uri(
      scheme: 'mailto',
      path: 'my.mail@example.com',
    );
    String  url = params.toString();
    if (await canLaunch(url)) {
      await launch(url);
    } else {
      print( 'Could not launch $url');
    }
  }

For all people still wondering why it is not working like I did. Remember that the simulator cannot handle mailto because the mail application is not available. If you use canLaunch before calling launch you will get more info.

I added this line in my manifest and I was able to start a call, open maps etc.

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

Be aware if you do that, you will have to declare the usage of this permission on Google Play when deploying a production release. – Peter Ivanics Mar 08 '23 at 07:20
