如何在很棒的通知中添加按钮单击功能

Question

这就是我在 flutter 中使用 Awesome notifications 创建通知的方式

AwesomeNotifications().createNotification(
            content: NotificationContent(
                id: 1,
                channelKey: 'basic_channel',
                title: "You spent some money?",
                body:
                    "We think, ₹ ${jsonObject['amount']} that was ${jsonObject['type']} to ${jsonObject['vendor']} belongs to this category: ${jsonObject['category']}",
                actionType: ActionType.Default),
            actionButtons: [
              NotificationActionButton(
                key: 'Approve',
                label: 'Approve',
              ),
              NotificationActionButton(
                key: 'Edit',
                label: 'Edit',
              )
            ],
          );

我想为批准和编辑选项添加不同的功能。执行此操作的确切语法是什么？

Answer 1

try {
      var response = await http.get(Uri.parse(url));
      if (Platform.isAndroid) {
        await Permission.storage.request();
      }
      var status = await Permission.storage.status;
      if (!status.isGranted) {
        await Permission.storage.request();
      }
      if (response.statusCode == 200) {
        String fileName = 'certificate_$certificateNumber.pdf';
        const downloadsFolderPath = '/storage/emulated/0/Download/';
        Directory dir = Directory(downloadsFolderPath);
        File file = File('${dir.path}/$fileName');
        OpenFile.open(file.path);
    
        AwesomeNotifications().createNotification(
          actionButtons: [
            NotificationActionButton(
              key: 'OPEN',
              label: 'Open',
            ),
          ],
          content: NotificationContent(
            payload: {'PDF_Downloader': dir.path, 'file': fileName},
            id: 1,
            channelKey: "PDF_Downloader",
            title: "Certificate Downloaded",
            body: "PDF has been downloaded successfully in Download Folder",
          ),
        );
    
        await file.writeAsBytes(response.bodyBytes);
        String date = DateTime.now().toString();
        setState(() {
          verificationDate = date;
        });

这是下载 PDF 文件并显示 PDF 已成功下载的通知并提供打开它的选项的示例 所以，我已将有效负载传递给通知

在您的情况下，您必须提供 Channel Key，并且必须为您的特定功能创建一个函数并替换

enter code here

dir.path

我希望它会起作用。
