How to fix: Image not showing when display images from the internet

Описание: If you are learning Flutter and you are trying to use the Image.network-widget to display an image from the internet with it’s URL, I believe there is a high probability that you will encounter the following problem.

For example, The screen-recording on the left side is what you will see when you run the app in debug mode on a virtual device or on a physical phone, everything works fine. but If you build a release-app.apk and install it on your phone, when you run the app , you will see something like the screen-recording On the right side which shows that well-displayed pictures are disapeared !

In fact, the reason for this problem is very simple, because each App installed on the mobile phone, needs to declare or request some permissions. For this case, because this widget accesses pictures from the internet, it needs internet permissions, so the only thing we need is Just adding this permission.
