flutter send email with url_launcher uri

I'm using url_launcher to send email with system email in my app. I'm using code below and this guy is doing so well.

void launchEmailSubmission() async {
    final Uri params = Uri(
      scheme: 'mailto',
      path: '[email protected]',
    );
    String url = params.toString();
    if (await canLaunch(url)) {
      await launch(url);
    } else {
      print('Could not launch $url');
    }
  }

But now I want to give it 'default' subject and hintText inside the mail body box(if hintText not possible, then normal text).

Is there any way to do this?

canLaunch and Launch are now deprecated and need to be replaced by canLaunchUrl and LaunchUrl.

Adapting the example from url_launcher

You get something like

String? encodeQueryParameters(Map<String, String> params) {
    return params.entries
      .map((MapEntry<String, String> e) =>
          '${Uri.encodeComponent(e.key)}=${Uri.encodeComponent(e.value)}')
      .join('&');
  }

void launchEmailSubmission() async {
    final Uri emailUrl = Uri(
      scheme: 'mailto',
      path: '[email protected]',
      query: encodeQueryParameters(<String, String>{
        'subject': 'Default Subject',
        'body': 'Default body'
      }),
    );
 
    if (await canLaunchUrl(emailUrl)) {
      await launchUrl(emailUrl);
    } else {
      print('Could not launch $emailUrl');
    }
  }

Below code working for me

    final String mMail = '[email protected]';
  _launchEmail() async {
    String email = Uri.encodeComponent(mMail);
    String subject = Uri.encodeComponent("App Support");
    String body = Uri.encodeComponent("");
    print(subject);
    Uri mail = Uri.parse("mailto:$email?subject=$subject&body=$body");
    if (await launchUrl(mail)) {
      //email app opened
    }else{
      //email app is not opened
    }
  }

'canLaunch and launch' are deprecated and shouldn't be used. Use canLaunchUrl and launchUrl instead. the urls must also be properly encoded.So, for that:

void _sendEmail() async {

   String? encodeQueryParameters(Map<String, String> params) {
   return params.entries
      .map((MapEntry<String, String> e) =>
          '${Uri.encodeComponent(e.key)}=${Uri.encodeComponent(e.value)}')
      .join('&');
     }

  final Uri emailLaunchUri = Uri(
    scheme: 'mailto',
    path: [email protected],
    query: encodeQueryParameters(<String, String>{
      'subject': 'Your Subject',
      'body':'Your body'
    }),
  );

  try {
     launchUrl(emailLaunchUri);
  } catch (e) {
    print("errorr. $e");
  }
 
}

'canLaunch' is deprecated and shouldn't be used. Use canLaunchUrl instead.

Let use

import 'package:url_launcher/url_launcher.dart';   
//...
final Uri params = Uri(
    scheme: 'mailto',
    path: '[email protected]',
    queryParameters: {
      'subject': 'Default Subject',
      'body': 'Default body'
    }
);
if (await canLaunchUrl(params)) {
  await launchUrl(params);
} else {
  print('Could not launch $params');
}

In addition to @Can-Kaplan answer, as of JANUARY 2023, launch and canLaunch has been depreciated and should be replaced with launchUrl and canLaunchUrl respectively.

So the updated code will be:

Future<void> launchEmailSubmission() async {
  final Uri params = Uri(
        scheme: 'mailto',
        path: '[email protected]',
        query: 'subject=Default Subject&body=DefaultBody');

    if (await canLaunchUrl(params)) {
      await launchUrl(params);
    } else {
      log('Could not launch $params');
    }
}

It is important to note that the following must be added to android>app>src>main>AndroidManifest.xml

  <queries>
    <intent>
      <action android:name="android.intent.action.SENDTO" />
      <data android:scheme="mailto" />
    </intent>
  </queries>

I hope this helps.

We did a little bit of each of the approaches. Things it considers:

  • It will work on web (canLaunch doesn't work for web, so replace with try/catch). Source.
  • It falls back to using clipboard if no mail client is available
  • It encodes the subject and body correctly with a helper function (otherwise you'll get + instead of space )

Usage

await EmailUtils.launchEmailSubmission(
         toEmail: '[email protected]',
         subject: 'I love this app',
         body: 'Your feedback below: \n');

email_utils.dart

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

class EmailUtils {
  
  /// Example
  /// ```dart
  /// await EmailUtils.launchEmailSubmission(
  ///       toEmail: '[email protected]',
  ///       subject: 'I love this app',
  ///       body: 'Your feedback below: \n');
  /// ```
  void launchEmailSubmission({
    required String toEmail,
    required String subject,
    required String body,
  }) async {
    String mailUrl = _getEmailString(toEmail: toEmail, subject: subject, body: body)
    // Use `try` instead of `canLaunch` because it doesn't work on web
    try {
      await launch(mailUrl);
    } catch (e) {
      await Clipboard.setData(ClipboardData(text: '$subject \n $body'));
      // Toast to user it was copied to clipboard
    }
  }

  static String _getEmailString({
    required String toEmail,
    required String subject,
    required String body,
  }) {
    final Uri emailReportUri = Uri(
      scheme: 'mailto',
      path: toEmail,
      query: _encodeQueryParameters(<String, String>{
        'subject': subject,
        'body': body,
      }),
    );

    return emailReportUri.toString();
  }

  /// Using `queryParameters` above encodes the text incorrectly.
  /// We use `query` and this helper function to encode properly.
  static String? _encodeQueryParameters(Map<String, String> params) {
    return params.entries
        .map((e) =>
            '${Uri.encodeComponent(e.key)}=${Uri.encodeComponent(e.value)}')
        .join('&');
  }
}

Don't forget to add these at your AndroidManifest.xml:

<queries>
  <!-- If your app opens https URLs -->
  <intent>
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="https" />
  </intent>
  <!-- If your app makes calls -->
  <intent>
    <action android:name="android.intent.action.DIAL" />
    <data android:scheme="tel" />
  </intent>
  <!-- If your app emails -->
  <intent>
    <action android:name="android.intent.action.SEND" />
    <data android:mimeType="*/*" />
  </intent>
</queries>

As @tsitixe pointed out you can use Piyushs answer and change queryParameters to query like this to avoid "+" symbols between the words in your E-Mail:

void launchEmailSubmission() async {
    final Uri params = Uri(
    scheme: 'mailto',
    path: '[email protected]',
    query: 'subject=Default Subject&body=Default body'
);

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

}

Try this!

void _launchURL() async {
    final Uri params = Uri(
      scheme: 'mailto',
      path: '[email protected]',
    );
    String  url = params.toString();
    if (await canLaunch(url)) {
      await launch(url);
    } else {
      print( 'Could not launch $url');
    }
  }

Try using queryParameters in Uri. You can achieve this in below shown way:

void launchEmailSubmission() async {
    final Uri params = Uri(
      scheme: 'mailto',
      path: '[email protected]',
      queryParameters: {
        'subject': 'Default Subject',
        'body': 'Default body'
      }
    );
    String url = params.toString();
    if (await canLaunch(url)) {
      await launch(url);
    } else {
      print('Could not launch $url');
    }
  }

It will open will default body and subject.
