Working solution

• So, the instructions after your if statement is executed whenever localdb is null or not

• The easist way to go about this is simply adding these instruction inside a else bloc.

• Just like so

Future<Database> get getlocaldbms async {
  if(localdbms != null) {
    return localdbms;
  }

//TODO: ADD THIS BLOC TO FIX THE ERROR
  else{
   localdbms = await initlocaldbms();
   return localdbms;
 }
}
