QUESTION
I am building this app and just have a small UI problem. I am using a ListView
builder. On the leading part of the tile, I want a circular icon to display with the desired image.
I believe my implementation is correct but when I run my code the circle avatar does come out on the leading part of the tile but it does not display the desired image. Instead, it just shows a blue circle on the leading end of each tile.
I am also getting an exception from the terminal. I will attach my code and the exception that I am getting. I would really appreciate suggestions from anyone. Thank you all!

QUESTION
I am trying to build a very simple Flutter app that shows the user four tiles. When the user clicks on one of the tiles, the app is supposed to open the URL in their browser that corresponds to that tile. For example, if the tile says "YouTube" then when that tile is pressed the app should take the user to YouTube. I have got something working but it doesn't work as intended. When you click on one of the tiles it doesn't take you to the desired website, it takes you to one of the other websites that I am trying to open within the app. For example, if you click on the tile that says Covid-19 Cases, the app opens Dr. John Campbell's YouTube Channel. I think my problem lies in the for loop in the _launchUrl method, but I am not sure how to fix it. I hope my explanation wasn't too long. I would appreciate suggestion from anyone, thank you all so much! I will attach the code and a screen shot of the app. I am not allowed to show pictures on my posts yet. I hope the URL isn't too much trouble.
