Flutter get_it factory not ready yet [Flutter get_it library with Floor database initialization]

Question

I'm trying to use floor library with get_it library to simplify call

simple implementation of this library is:

final sl = GetIt.instance;

Future<void> init() async {
  /// database
  sl.registerLazySingletonAsync<AppDatabase>(
      () => $FloorAppDatabase.databaseBuilder('app_database.db').build());

  /// http client
  sl.registerLazySingleton<ApiService>(
      () => NetworkModule().getHttpProvider().getService());

  /// call dao
  sl.registerLazySingletonAsync<UserDao>(
      () async => (await sl.getAsync<AppDatabase>()).userDao);

in main() function i call:

await sl.init();

but i get error:

You tried to access an instance of UserDao that is not ready yet
'package:get_it/get_it_impl.dart':
package:get_it/get_it_impl.dart:1
Failed assertion: line 404 pos 9: 'instanceFactory.isReady'

What's wrong in my code ?? Thank you

Answer 1

use dependsOn refer to https://pub.dev/packages/get_it#automatic-using-dependson and chaining that its each module.

e.g:

getIt.registerSingletonAsync<AppDatabase>(() async => $FloorAppDatabase
      .databaseBuilder('app_database.db')
      .addCallback(callback)
      .build());

getIt.registerSingletonWithDependencies<UserDao>(
      () => getIt<AppDatabase>().userDao,
      dependsOn: [AppDatabase]);
