flutter - 使用 Flutter WEB 将内容分享到社交媒体

问题描述

我在flutter android/iOS上使用了几个库来共享内容，直到最近我想在flutter WEB上实现共享功能。虽然我使用了相同的库，但它给出了 MissingPluginException 错误。这很可能是因为 Flutter Web 平台没有配置。

Overflow on channel: social_share.  Messages on this channel are being discarded in FIFO fashion.  The engine may not be running or you need to adjust the buffer size if of
the channel.
Error: MissingPluginException(No implementation found for method shareWhatsapp on channel social_share)

代码：

class SocialMediaLogo extends StatelessWidget {
  final String logo;
  SocialMediaLogo(this.logo);

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: EdgeInsets.all(5),
      child: RaisedButton(
          onPressed: () async {
            SocialShare.shareWhatsapp("Hello World \n https://google.com")
                .then((data) {
              print(data);
            });
          },
          child: Image(
            image: AssetImage("icons/$logo.png"),
            height: 35,
            width: 35,
            fit: BoxFit.cover,
          )),
    );
  }
}

有没有办法做到这一点？或者任何已实现的 Web 插件？

解决方案

对于您可以使用的文本，share_plus:但仍然很难与之共享图像，但是对于文本，它可以正常工作
