imagecache | Image generation with presets | Computer Vision library

in the assetImage the synatx is usually like this :

image: AssetImage("images/loginBackground.png")

also if you didn't enable your assets in pubspec.yaml by doing this in your assets section :

The imports is slightly different on Nativescript 8

So, after a long search I eventually found the problem. The documentation is not really clear on this but:

You can pass your task as an inout parameter. A simplified version of your function would be:

After trial and error this worked:

Update your ImageLoader code to let you check if an image is already in the cache and return it synchronously to you.

Then when you load the cell, if it has the image, set it immediately. If it doesn't have the image, have the completion handler instead do a reload on the cell at that index path. Then, since the image is now cached, your regular cell loading code will be able to populate the image. Just make sure you only request the image if it wasn't already set from the cache.

The way your code is written right now, whether it set an image from the cache or not in your completion handler, it's endlessly trying to reload the row that it just set the image on, which is also going to impact performance. Hence why, as I said, you should only reload the cell if a new image was just downloaded. And don't set the image in the completion handler, just reload the row.

The URL that you are saving in Firebase is the path to your local image asset, which cannot be passed to a NetworkImage widget.

In other words, the local image is not a valid URL or hosted on the internet, so you cannot use it in the NetworkImage widget.

Now, to solve your issue, you can do two things:

1. Check whether the user has chosen the signInWithEmail method & use Image.asset instead of NetworkImage.

2. Upload your image to your server / Firebase & provide the uploaded image's URL.

Please read the documentation of the package you are using. It states

If you want to display barcodes in a Flutter application, use pub:barcode_widget.

You need to add barcode_widget as a dependency in your pubspec.yaml. Then use the BarcodeWidget widget to display your barcode.
