Usage

import 'package:memory_checker/memory_checker.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      ...
      navigatorObservers: [
        LeakObserver()
      ],
    );
  }
}

LeakObserver will notify if there are some leaks found by VMService

        android:usesCleartextTraffic="true" <!-- This Line -->
        android:icon="@mipmap/ic_launcher">

iOS

<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.
