解决 'showSnackBar' is deprecated and shouldn't be used

3 min read

换成这个了

ScaffoldMessenger.of(context).showSnackBar( SnackBar( content: Text("Incremented"), duration: Duration(milliseconds: 300), ), );

Demo如下

 IconButton(
                  icon: const Icon(Icons.markunread_sharp),
                  onPressed: () {
                    Clipboard.setData(ClipboardData(text: '![$name]($url)'));

                    ScaffoldMessenger.of(context)
                        .showSnackBar(const SnackBar(content: Text("复制成功")));
                  },
                ),
