I am trying to release a flutter app on play store. Debug app is working fine but i am getting the failed host look up error in release app on playstore. I'm a student. Please help me what am I doing wrong

did you add the internet options in the release manifest?

No, I didn't. But i didn't add in the debug app as well but that's working just fine.

please make sure to add the internet permissions

could also be a flutter version problem
