Android

This behavior may be omitted following migration guide: https://flutter.dev/docs/release/breaking-changes/network-policy-ios-android.

add in android/app/src/main/AndroidManifest.xml:

<application
        android:name="io.flutter.app.FlutterApplication"
        android:label="receipt"
        android:usesCleartextTraffic="true" <!-- This Line -->
        android:icon="@mipmap/ic_launcher">

iOS

Allow insecure/HTTP requests globally across your application on iOS, you can add this to your ios/Runner/info.plist under the main dictionary definition:

<key>NSAppTransportSecurity</key>
<dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
</dict>

Be warned that you will need to have an explanation for Apple's review team when enabling this, otherwise your app will get rejected on submission.
