在复制文字扑来后显示吐司消息

Question

复制SelectableText窗口小部件的文本后，我想显示敬酒消息。但是我看不到这样做的选择。我应该怎么办？

Answer 1

以下工作对我来说，在将数据复制到设备剪贴板之后显示出吐司消息：

 Clipboard.setData(ClipboardData(
              text: global_variables.myQRpartnerToStayInTouchWithUid))
          .then(
              (_) => ScaffoldMessenger.of(context).showSnackBar(const SnackBar(
                      content: Text(
                    'Copied to clipboard',
                    textAlign: TextAlign.right,
                  ))));

Answer 2

            Clipboard.setData(ClipboardData(text: "message"))
                .then((_) {
              
 ScaffoldMessenger.of(context).showSnackBar(flutterToast("Copy,false"));
            });
        
// flutterToast is common widget like this
// packages fluttertoast latest version recommended

flutterToast(String massage, bool set) {
  Fluttertoast.showToast(
     msg: massage,
     toastLength: Toast.LENGTH_SHORT,
     gravity: set ? ToastGravity.TOP : ToastGravity.BOTTOM,
     timeInSecForIosWeb: 1,
     backgroundColor: set ? Colors.red : Colors.green,
     textColor: Colors.white,
     fontSize: 16.0);
}
