The issue is with an http.get
request, for some reason I can't access my API on release versions, but it runs smoothly in debug mode.
I already gave internet permission on android/app/AndroidManifest.xml, and I already tested the permission by using Image.network, and I got the image.
I fix this issue, It's because I edit my packages name, I think there's some problem on there. I build new project and it run smoothly
