flutter app api calls never returns in release mode

my flutter app works on debug mode getting data from api and all. but after I built the app in release mode and try to open it on my actual phone. It is not working getting the data from the api.

Things I have tried:

1. <uses-permission android:name="android.permission.INTERNET" /> and android:usesCleartextTraffic="true" //added in AndroidManifest.xml

2. flutter clean and flutter build apk --release and flutter build apk --split-per-abi --no-sound-null-safety

3. added shrinkResources and minifyEnabled in android/app/build.gradle file.

   buildTypes {
   release {
    signingConfig signingConfigs.config
    shrinkResources false //here
    minifyEnabled false //here
   }
   

   }

Any help is appreciated

If you wanted to find your error run it on direct release mode it can show what is cussing the error/crash

Menu->Run->ReleaseMode
