我搜索到其它一些插件也有类似问题，这个情况应该是升级 flutter 到 v1.12.13 版本后出现的。希望开发者能修复一下～

For example, when calling Progresshud.setDefaultMaskTypeBlack(); . HUD should not appear, but it will appear on Android. But there is no problem on iOS.

Please check the problem. Thank you.

Execution failed for task ':ovprogresshud:verifyReleaseResources'.

1 exception was raised by workers: com.android.builder.internal.aapt.v2.Aapt2Exception: Android resource linking failed

It's fine on iOS, but it's does not work on Android.

On Android, it stops at code: await Progresshud.showWithStatus('Login ...'); // blocked here the following code not excuting Anyone has the same problem.

Calling Progresshud.show()/dismiss() works fine, but when calling showSuccess or Info or Error make the screen blocked since the progresshud does not dismiss for the second time it's called.

Progresshud.showSuccessWithStatus("Please wait...");
//Do something a bit long 2 - 3 seconds
await Progresshud.dismiss();

When one calls showLoading() and showSuccess(), it closes the first dialog then shows the 2nd one

would be nice to have a way to have an extra parameter to note close the current dialog and just change the dialog content, and then closing it like when showSuccess() is called.

I tried to use ovprogresshud (https://pub.dev/packages/ovprogresshud) to show download progress. I used flutter_downloader (https://pub.dev/packages/flutter_downloader) for download.

I try to update progress via an Isolate, but receive errors. (If I call Progresshud.showWithStatusdirectly in my code, say before download, it works)

My code:

ReceivePort _port = ReceivePort();
...

IsolateNameServer.registerPortWithName(
        _port.sendPort, 'downloader_send_port');
_port.listen(
      (dynamic data) {
        String id = data[0];
        DownloadTaskStatus status = data[1];
        int progress = data[2];
        if (status == DownloadTaskStatus.complete) {
        } else if (status == DownloadTaskStatus.running) {
          Progresshud.showWithStatus("%$progress Downloaded");
        }
      },
      onDone: () {
        checkIfDictionaryUnzipped(DBFilePath);
      },
      onError: (error) {},
    );

The error I receive:

Unhandled Exception: PlatformException(error, Attempt to invoke virtual method 'android.view.ViewParent android.view.ViewGroup.getParent()' on a null object reference, null)

Allow to change hud background and foreground colour. Icon can also be change to something else, but still configurable to use out own child property so can use loading animation widget.
