Ask yourself: is assets/Upload/Item/214b5d5c-ca86-45f5-bb45-7850559a23bb.jpg a valid URL? — Riwen

You are using the wrong image provider class to provide locally stored images. The proper use-case for NetworkImage() class is providing remotely hosted URLs such as hosted in web/storage bucket.

In your case, in order to provide an image locally stored in the assets folder, you need to use AssetImage() instead. Please follow the documentation for more details.

Image is stored in an array then I call the array through network image also another issue is this Exception: Invalid image data

Prabhath Darshana Over a year ago

Unless array items are fully qualified remote host URLs such as https://example.com/image NetworkImage provider can not render them. According to provided snippet on your question, you want to render some images from the assets directory of the app. Therefore you need to use AssetImage instead of no matter how you have stored the data.

Have you enabled the assets directory in pubspec.yaml? the assets directory should enable by adding the following lines under flutter: in pubspec.yaml. There would be a commented version available describing how to enable this. flutter: # To add assets to your application, add an assets section, like this: assets: - assets/images/
