Attempt to execute code removed by dart aot compiler

When running a release build of the Flutter application, an exception is thrown leading to a blank white screen.

realm_services file mentioned in logs:

import 'package:realm/realm.dart';

import '../screens/home/models/note_model.dart';
import '../screens/home/models/todo_model.dart';

class RealmServices {
  late Realm realm;

  RealmServices() {
    realm = getRealm();
  }

  Realm getRealm() {
    final Configuration config;
    config = Configuration.local(
      [
        TodoModel.schema,
        NoteModel.schema,
      ],
      schemaVersion: 2,
    );

fyi - @alexmarkov - per the log:

Attempt to execute code removed by Dart AOT compiler (TFA)

Is there any temporary workaround for this issue? Or I should wait for a fix?

I'm not in a rush or anything but if I wanted to build a release build for testing.

@milindgoel15 rewrite your code as:

  Realm getRealm() {
    final Configuration config = Configuration.local(
      [/* ... */],
      schemaVersion: 2,
    );

    return Realm(config);
  }

This should fix it.

  Realm getRealm() {
    final Configuration config = Configuration.local(
      [/* ... */],
      schemaVersion: 2,
    );

    return Realm(config);
  }

So, say for instance, I want to provide user an ability to choose the flexible sync approach instead of local configuration. I was initially doing a check using if else as:

If the user decides to login, the configuration picks up the flexible sync otherwise local which was also breaking due to this dart aot compiler.

Can I still do it? Because we are now declaring the config data directly instead of assigning them later.

Maybe use of late ig.

This should fix it.

That fixed it. Thanks

@milindgoel15 you can use ternary (or Dart 3 switch expression) or alternatively you can remove the final and make the variable nullable as a temporary workaround:

  Realm getRealm() {
    Configuration? config;
    if (something) {
      config = /* ... */;
    } else {
      config = /* ... */;
    }

    return Realm(config!);
  }
