Conditionally Reject Uploaded Image

[AiMAnsarie]

Hi,

I see a lot of older implementations of custom logic, for when the image is uploaded but before it's accepted, but none of those are working anymore.

Is there a way to add custom logic when the image is selected by the user? I want to be able to reject it based on it's size, dimensions and a couple other factors. I also want to be able to convert the image to bytes and use Image.memory to display the image.

I see imageProviderBuilder method but it's not asynchronous and it does not allow me to reject the image altogether.

Thanks!
