PD not getting dismissed some times

[Vinayak27Mobility]

Describe the bug
When dealing with Asuncións method, showing PD with Util class across app.

To Reproduce
Calling update record async Firestore method and showing Updating PD and post method calling Util.dismissProgressBar(). Please refer the code:

Util Class code :
Code :
static showProgressBar(BuildContext context, String message) async {
if(pDialog == null) {
pDialog = ProgressDialog(context,
type: ProgressDialogType.Normal,
isDismissible: false,
showLogs: true);
}
pDialog.style(message: message);
await pDialog.show();
}

static Future dismissProgressBar() async {
if (pDialog != null && pDialog.isShowing()) {
return pDialog.hide();
}
}

Calling Class Code:

try {
NetworkManager().updateChild(updatedChild).then((value) {
if (_profileImageStatus == AppConstants.profileImageUpdated) {
uploadFile(updatedChild).then((value) {
Util.dismissProgressBar().then((value) {
if (this.mounted) this.setState(() {});
});
});
} else {
//loggedUser = value;
Util.dismissProgressBar().then((value) {
if (this.mounted) this.setState(() {});
});
}
});
} catch (e) {
Fimber.e(e.toString());
}

Expected behavior
PD should get dismissed every time post method complete

It's because the pDialog is trying to hide itself when the dialog is not shown completely.
The isShowing flag is set after 200ms (the default transitionDuration of the progress_dialog).

Some workaround you can wait to 200ms when the dialog failed to hide itself.

static Future dismissProgressBar() async {

if (dialog != null) {
    bool isHidden = await dialog.hide();
    if (!isHidden) {
      Future.delayed(Duration(milliseconds: 200), (){
        dialog.hide();
      });
    }
}

Hi!

I'm having the same issue, but I'm using the await keyword.

await state.progress.fold<Future>(
      () => _downloadDialog.hide(),
      (progress) => _downloadDialog
          .show()
          .then((_) => _downloadDialog.update(progress: progress)),
    );
log('showing: ${_downloadDialog.isShowing()}');

The log is printing showing: false even though the dialog is being shown. Any idea?

OBS: The code above is being called in a BLoC listener (which is called multiple times).
