My android app in flutter not fetching data from api in release.apk but works fine in debug mode or in the emulator, I tried everything I also added internet permission in my AndroidManifest.xml code but nothing works for me.

         In most cases you can leave this as-is, but you if you want to provide
         additional functionality it is fine to subclass or reimplement
         FlutterApplication and put your custom class here. -->

    </application>

</manifest>

i also add network_security_config.xml to app/main/res/xml

<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>

</network-security-config>

I am trying from last one week but nothing works for me. My api is in http format so i added network_security_config.xml file
