Custom_Empty widget is flutter plugin which is designed to notify user about some event.

I am trying to use this (EmptyWidget) package in my application to display widget with text and image, when there is no data available to display to the user.

I am using the following code, I do not want to use packageImage but instead i want to use asset image from my project. I have also noticed if i don't use packageImage parameter or set it to null, I get Error: Null check operator used on a null value.

EmptyWidget( image: 'images/test.jpg', packageImage: PackageImage.Image_3, title: 'No Data Found', );

Even if I specify my image path using image attribute, It doesn't display image at all and I can't ignore packageImage attribute. I don't know if its a bug , it seems like that it is mandatory to use packageImage attribute and use available images from it. Could you please specify how could I use custom image from project and in some cases if i don't need to display image but text only, how could i do it.

Thanks,

Describe the bug _EmptyListWidgetState created a Ticker via its TickerProviderStateMixin, but at the time dispose() was called on the mixin, that Ticker was still active. All Tickers must be disposed before calling super.dispose().

Tickers used by AnimationControllers should be disposed by calling dispose() on the AnimationController itself. Otherwise, the ticker will leak.

Describe the bug Exception is thrown, possible memory leak on devices.
