Question

我正在尝试

launch("tel://21213123123")

但是，我遇到了以下错误！

PlatformException (PlatformException(error, Calling startActivity() from outside of an Activity  context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?, null))

在此文件中

message_codecs.dart

这是我的错误日志

新版本的urlLauncher 4.0.2插件也遇到了相同的问题

我降级到3.0.3，并且一切正常，因此存储库中可能存在错误。

pubspec.yaml

<ul>
    <li *ngFor="let list of List1">{{list.name}}        
        <ul *ngIf="list.name === 'C'">
            <li *ngFor="let list_2 of List2" >{{ list_2.name }}
            </li>
        </ul>
    </li>
</ul>

示例代码（摘自git repo，但对我而言适用于3.0.3）

https://github.com/flutter/plugins/tree/master/packages/url_launcher

 url_launcher: 3.0.3

有关该插件的所有可用版本，请参见此处。 https://pub.dartlang.org/packages/url_launcher#-changelog-tab-
