Steps to reproduce
- Create an
Uriwith "sms" scheme, set message to any string that contains character "&". - run
launchUrl(uri, mode: LaunchMode.externalApplication)
Expected results
The message given to Uri properly shows on sms body field.
Actual results
The message is not shown as it's given on the Uri.
If the original message was "Hello & World", depending on how I created Uri, it appears either "Hello%20%26%20World" or "Hello ".
final uri = Uri(
scheme: 'sms',
queryParameters: <String, String>{
'body': Uri.encodeComponent('Hello & World'),
},
); // result: "Hello%20%26%20World"final message = Uri.encodeComponent('Hello & World');
final uri = Uri.parse('sms:?body=$message'); // result: "Hello "Code sample
Code sample
import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return const MaterialApp(
title: 'Flutter Demo',
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({super.key});
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
ElevatedButton(
onPressed: () async {
/// Code example provided on README
final uri = Uri(
scheme: 'sms',
queryParameters: <String, String>{
'body': Uri.encodeComponent('Hello & World'),
},
);
launchUrl(uri, mode: LaunchMode.externalApplication); // result: "Hello%20%26%20World"
},
child: const Text('Test 1'),
),
const SizedBox(height: 20),
ElevatedButton(
onPressed: () async {
/// Another way that I tried
final message = Uri.encodeComponent('Hello & World');
final uri = Uri.parse('sms:?body=$message');
launchUrl(uri, mode: LaunchMode.externalApplication); // result: "Hello "
},
child: const Text('Test 2'),
),
