我如何将新的launchurl()方法与a mailto使用:&quot:关联?
我的应用程序中有一个小链接,上面写着“向我们发送电子邮件”。当您单击它时,我希望默认电子邮件应用程序打开,并通过电子邮件开始到我们的电子邮件地址。我曾经在url_launcher
包中使用abought()
方法的方法完全做到这一点:
import 'package:url_launcher/url_launcher.dart' as url;
Future<bool?> pressedSendUsEmail() async {
bool? success;
try {
print('Pressed Send us an e-mail...');
success = await url.launch('mailto:[email protected]'); // Works like a charm...
print('success is $success');
} catch (e) {
print('Caught an error in Send us an e-mail!');
print('e is: ${e.toString()}');
}
return success;
}
但是现在,我得到了警告,说abination()
/代码>已弃用!我应该改用
launchurl()
。但是lainingurl()
不采用字符串参数,它需要一个uri参数...而且我不知道如何正确编写此URI,以便它可以做我想要的!我尝试了:
success = await url.launchUrl(Uri(path: 'mailto:[email protected]'));
但是这引发了一个错误,因为它无法解释“:”字符。我已经尝试过:
success = await url.launchUrl(
Uri.https('mailto:[email protected]', ''),
);
这启动了链接,但是在浏览器中...并且它没有启动电子邮件到预先打印的地址。我尝试添加:
success = await url.launchUrl(
Uri.https('mailto:[email protected]', ''),
mode: url.LaunchMode.externalApplication,
);
这为我提供了一个可以打开链接的外部应用程序的选项,但是不幸的是,只列出了浏览器应用程序...而不是电子邮件应用程序!
我应该如何编写我的命令来制作lunageurl()
只需执行旧启动()
做的事情?最感谢帮助!
编辑:
在下面令人满意地回答了这个问题之后,我现在有一个后续QN:
在应用程序的另一部分中,在某个地方,用户可以在链接中输入链接,而我曾经用启动来启动它()
...还有一种简单的方法吗?
因为在这种情况下,我不知道该链接是否是HTTP或HTTPS,或者确实是Mailto:!我只希望它尝试按书面方式启动链接,只要它正确编写,它就会起作用。
I have a little link in my app that says "Send us an e-mail". When you click it, I want the default email app to open, with an email started to our email address. I used to make it do exactly that with the launch()
method in the url_launcher
package like this:
import 'package:url_launcher/url_launcher.dart' as url;
Future<bool?> pressedSendUsEmail() async {
bool? success;
try {
print('Pressed Send us an e-mail...');
success = await url.launch('mailto:[email protected]'); // Works like a charm...
print('success is $success');
} catch (e) {
print('Caught an error in Send us an e-mail!');
print('e is: ${e.toString()}');
}
return success;
}
But now, I get a warning saying launch()
is deprecated! I should use launchUrl()
instead. But launchUrl()
doesn't take a String argument, it takes a Uri argument... and I don't know how to write this Uri correctly, so that it does what I want! I tried:
success = await url.launchUrl(Uri(path: 'mailto:[email protected]'));
but that throws an error, because it can't interpret the ":" character. I've tried:
success = await url.launchUrl(
Uri.https('mailto:[email protected]', ''),
);
and that launches the link, but in the browser... and it doesn't start up an e-mail to the pre-printed address. I tried adding:
success = await url.launchUrl(
Uri.https('mailto:[email protected]', ''),
mode: url.LaunchMode.externalApplication,
);
and that gives me an option of which external app to open the link with, but unfortunately, only browser apps are listed... not the email app!
How should I write my command to make the launchUrl()
just do exactly what the old launch()
did?? Most grateful for help!
Edit:
After that question was satisfactorily answered below, I now have a follow-up qn:
In another part of the app, there is a place where the user can type in a link, and I used to launch it with launch()
... Is there a simple way to do that, as well?
Because in that case, I don't know if the link is gonna be a http or a https or indeed a mailto:!... and I would prefer not having to write lots of code to find that out! I just want it to try and launch the link exactly the way it's written, and so long as it's written correctly, it will work.

尝试以下操作:
Try this:
使用已经内置的服务
uri
...Using the service already built-in to
Uri
...内置查询构建器仅适用于HTTP/HTTPS。
对于其他任何内容,都应使用以下内容,否则您将拥有“+”而不是空格:
源: url_launcher文档
The built-in query builder only work correctly for http/https.
For anything else, the following should be used, otherwise you will have "+" instead of spaces:
