My flutter app not fetching data from api in release.apk but works in debug mode

Question

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. Please kindly solve the issue I am new to flutter and android development.

AndroidManifest in app/src/main file code

 <manifest
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        package="xyz">
        <!-- io.flutter.app.FlutterApplication is an android.app.Application that
             calls FlutterMain.startInitialization(this); in its onCreate method.
             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. -->

                     to determine the Window background behind the Flutter UI. -->

                     gap between the end of Android's launch screen and the painting of
                     Flutter's first frame. -->

                </intent-filter>
    
            </activity>
            <!-- Don't delete the meta-data below.
                 This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
            <meta-data
                android:name="flutterEmbedding"
                android:value="2" />
        </application>
    
    </manifest>

Have you found any solution. I am also stuck in the the same point? — Humayun Rahi, Apr 18 '21 at 05:39

I solved the problem by adding shrinkResources false and minifyEnabled false in the android/app/build.gradle file under buildTypes

buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        shrinkResources false
        minifyEnabled false
        signingConfig signingConfigs.debug
    }
}

Please hide your api key first. The api not working must be because of api keys. You need different ones . Follow this

Android: automatically choose debug/release Maps v2 api key?

Make sure that the Android manifest for the release app declares the INTERNET permission. See https://flutter.dev/docs/development/data-and-backend/networking
