@MrErkinjon Hi, thanks for reporting. I can't repro it. I put your (slightly modified) code into the example app and it worked without problems. Please provide a sample project and the output of flutter doctor. Thank you.

Hey guys!

I rushed over the same problem here. I also get the same error. I guess you are using Flutter 3.7.0 or lower.

The Problem here is, that Columns are not const for Flutter 3.7 and lower. I just tried it out with a project where I have the a newer Version (3.13.9). So I just looked up and found that columns are const since 3.10

To solve your problem, downgrade to easy_image_viewer: 1.3.2
