Multiple progress dialog instance in a statefull widget

[bagus-repository]

Describe the bug
I got strange condition if I have multiple progress dialog instance in a Statefull Widget, progress dialogs instantiate on build widget like this

progressDialog = new ProgressDialog(context,
        type: ProgressDialogType.Normal, isDismissible: true, showLogs: false)
      ..style(
        message: msg ?? "Memproses...",
        borderRadius: 8.0,
        backgroundColor: Colors.white,
        elevation: 5.0,
        messageTextStyle: TextStyle(fontSize: 16.0),
        // progressWidget: CircularProgressIndicator(),
      );
    progressDownloadDialog = new ProgressDialog(context,
        isDismissible: false, type: ProgressDialogType.Download)
      ..style(
        message: "Mendownload...",
        borderRadius: 8.0,
        backgroundColor: Colors.white,
        elevation: 5.0,
        messageTextStyle: TextStyle(fontSize: 16.0),
        progress: 0.0,
        maxProgress: 100,
        progressTextStyle: TextStyle(
            color: Colors.black, fontSize: 13.0, fontWeight: FontWeight.w400),
   );

If I call progressDialog.show() or progressDownloadDialog.show(), the progressDownloadDialog will be triggered.

just tell me one thing, why do one require two instances if the work can be done with only one instance

Ah my bad, I do not see the source code, I think the ProgressDialogType just for this purpose

Expanded(
          child: _progressDialogType == ProgressDialogType.Normal
              ? Text(_dialogMessage,
                  textAlign: TextAlign.justify, style: _messageStyle)
              : Stack(
                  children: <Widget>[
                    Positioned(
                      child: Text(_dialogMessage, style: _messageStyle),
                      top: 30.0,
                    ),
                    Positioned(
                      child: Text("$_progress/$_maxProgress",
                          style: _progressTextStyle),
                      bottom: 10.0,
                      right: 10.0,
                    ),
                  ],
                ),
        ),

So if I can't instantiate multiple instance (Normal and Download), I would just give the type to ProgressDialogType.Normal and update the percentage in the text instead of progress property.

That's ok, thanks for replying. My suggestion is remove the Type and add child property for customize the content element (you know, just if can be done 😄 )
