@manjotsidhu flutter test --coverage is failing due to the use of MediaQuery as it could not find generic widgets.

Upon changing tests, still, the error was persistent, so I changed the height of the container and let the height of the image remain 300. With this, the issue is resolved, and no CI tests fail.
