【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?
