Flutter Android app crashing on launch saying “waiting on observatory port…”

I am using Flutter to create an app and I didn't test it on android before implementing many features (I have been using iOS simulator as my primary testing software). Now that I have started using the android simulator because I wanted to configure firebase for the android app as well but, It crashes for some reason. Still works well on iOS but not on android. Flutter doctor has no issues and the console shows "waiting on observatory port...".

here's my project link if you guys want to test it for yourself.
