When the network is lost the message "Reading image file ..." is printed but the image is not loaded

When network is lost the message "Reading image file ..." is printed but the image doesn't load. With a network connection, the image is read from file and displayed properly.

You mean, without internet it doesn't load from file? It tries to load from file before trying the internet, so that's strange. Or I didn't understand what you mean. Could you give me more detail?

Thanks for your reply. Yes you get it right. As you said it read saved file but without internet it doesn't show the image, while with the Internet connection this problem doesn't exist. I'm using the code you provided in example section.

Ok, that's really strange. I'll have a look at it.

I have upgraded the package to Flutter 1.20. There were indeed some changes I needed to make in the ImageForCanvas class, but not for the NetworkToFileImage class. In any case you are not using Flutter 1.20.

I can't reproduce the problem you describe. What I did was this:

1. Run once the example from https://github.com/marcglasberg/network_to_file_image/blob/master/example/lib/main.dart
   This would download the image and save it to file.

2. Turn off the internet, by putting the emulator into airplane mode.

3. Run again the example. The image is displayed.

Is it possible to upload an image through Assets?
My app receives an image from the network, but when the image is null, I would like to load some of the Assets.

@luciano01 I don't understand your question, you have to explain better what you want. But, please, open a new issue, since it has nothing to do with this question. I am going to close this issue since I got no more replies.
