How to use with floor library?

[jackyhieu1211-hn]

Hello

• I use https://pub.dev/packages/floor

@Database(version: 1, entities: [Person], views: [Name])
abstract class AppDatabase extends FloorDatabase {
  PersonDao get person;
}

Use in main.dart

var database = await $FloorAppDatabase.databaseBuilder('test.db').build();
database.person.getAllPerson();

===> OK

In get_id. I use like below

   static Future<void> _registerDatabase() async {
    AppDatabase database =
        await $FloorAppDatabase.databaseBuilder('test.db').build();
    sl.registerLazySingletonAsync(() async => database.person);
  }

in main.dart

I use like below

class _MainAppState extends BaseState<MainApp> {
  Person person = sl.get();

  @override
  Widget body() {
    get();
    return Container();
  }

  void get() async {
    print("DATABASE =========> ${person.getAllPerson()}");
  }
}

And get error

You tried to access an instance of Person that was not ready yet
'package:get_it/get_it_impl.dart':
Failed assertion: line 272 pos 14: 'instanceFactory.isReady'

Please help me. thank you very much.

you don't have to register the person in GetIt but the database.

Instead of

   static Future<void> _registerDatabase() async {
    AppDatabase database =
        await $FloorAppDatabase.databaseBuilder('test.db').build();
    sl.registerLazySingletonAsync(() async => database.person);
  }

do something like:

   static Future<void> _registerDatabase() async {
    sl.registerLazySingletonAsync<AppDatabase>($FloorAppDatabase.databaseBuilder('test.db').build());
  }
```

Then before you access it wait with 

```
sl.allReady()
```
after that you can access person over

```
sl<AppDataBase>().person;
```

I close issue. And remove it to #101

using 7.2.0, and floor 1.3.0, database never get ready.

 registerLazySingletonAsync<BookDatabase>(() async =>
        await $FloorBookDatabase.databaseBuilder("app_database.db").build());
    registerSingletonWithDependencies<BookDao>(
        () => get<BookDatabase>().bookDao,
        dependsOn: [BookDatabase],
        signalsReady: true);

at this point, line 1 never execute no matter what. I've waited so long... Any ideas of whats going on?

return FutureBuilder(
        future: GetIt.instance.allReady(),
        builder: (BuildContext context, AsyncSnapshot snapshot) {
          if (snapshot.hasData) {
            //line 1
          } else {
            //line 2
          }
        });
