Displaying Images Instead of URLs in Flutter

When developing a Flutter application, one common issue that developers encounter, especially those who are new to the framework, is displaying images from URLs. Instead of the image appearing on the screen, you might see the URL text. This often leads to confusion. But fear not! In this guide, we will go through a simple solution to this problem, ensuring that images are rendered correctly in your app.

Understanding the Problem

Imagine you are creating an application that displays several plants, and you want to showcase their images next to their names. However, instead of seeing a beautiful plant picture, you might see the URL of the image. This can make your app look unprofessional and confusing for users.

Example of the Issue

In the provided Flutter code sample, you have a list of plants and their respective image URLs. Here’s a snippet showing the issue:
