How to show a container / dialog next to an icon when the icon is tapped?

Hi I'm trying to create a screen that have bunch of container with a child of row that have a text and a Icon (the red one - can be seen on the image). So when I click the icon I want to show a dialog right next to the icon. I tried using aligned_dialog but the positioning is really hard to do, I want it to be instantly next to the icon just like the image.
Is there any package or widget that I can use to achieve this ?
You can check this package: https://pub.dev/packages/just_the_tooltip
