我正在使用来自 url_launcher 页面的文档：https ://pub.dev/packages/url_launcher#android

AndroidManifest.xml：

<queries>
  <!-- other intents ... -->
  <intent>
    <action android:name="android.intent.action.SEND" />
    <data android:mimeType="*/*" />
  </intent>
</queries>

代码：

final Uri emailLaunchUri = Uri(
  scheme: 'mailto',
  path: 'smith@example.com',
);

launch(emailLaunchUri.toString());

并得到下一个错误：

E/flutter (11956): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: PlatformException(ACTIVITY_NOT_FOUND, No Activity found to handle intent { mailto:smith@example.com }, null, null)

终于在这里找到了答案：https ://stackoverflow.com/a/61800530/2694052

需要在 AndroidManifest.xml 中添加另一行：

<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>
