我正在使用 url_launcher: ^5.4.10 启动不同的 url 方案，但外部链接在 ios 模拟器上工作正常，但无法打开手机拨号盘和默认电子邮件地址，而在 Android 设备上工作正常
我在ios模拟器上测试过它而不是真实设备
如果我尝试打开拨号盘，这里是例外
{PTS: 6.000 s, decode: 32.021 ms},
]
flutter: could not launch tel:+18002509646
当我尝试打开电子邮箱时，我收到了异常情况

如果您想使用外部链接，请将这些行添加到您的
myproject/ios/Runner/Info.plist<key>LSApplicationQueriesSchemes</key>
<array>
<string>http</string>
<string>https</string>
</array>
我有一个建议，你可以尝试发出这样的命令吗：
1。代码检查
command = "tel://214324234"
// Also, try using Future in place of void
Future<void> customLaunch(command) async {
if (await canLaunch(command)) {
await launch(command);
} else {
print(' could not launch $command');
}
}
2。格式检查：一定要检查一下，如果
tel:<phone number>tel:<phone_number>3.更新检查：另外，还有一个新的更新，即
5.5.0pubspec.yaml4。真实设备检查： 有时会发生模拟器不支持某些功能的情况。我请求你拿到一个真正的
iOS Device这对我有用：
import 'dart:io' show Platform;
/// Dial
Future<void> contactDial(String number) async {
await _launchCaller(number);
}
_launchCaller(String number) async {
String url = Platform.isIOS ? 'tel://$number' : 'tel:$number';
if (await canLaunch(url)) {
await launch(url);
} else {
throw 'Could not launch $url';
}
}
确保您已将 LSApplicationQueriesSchemes 键添加到您的文件中，其中的数组值包含您要打开的 URL 方案。例如：
<key>LSApplicationQueriesSchemes</key>
<array>
<string>googlechrome</string>
<string>googlechromes</string>
<string>http</string>
<string>https</string>
</array>
