If you see the sentry catch (ask permission to enter), the problem originates here because Restaurants table has different attributes than resturant.toJson(). Look at the Restaurant Model, you easily see the meals property, which is defined as @JsonKey.

This problem could be easily fixed if you just remove meals key from restaurant.toJson() returned object and insert the filtered restaurant to database. As you can see, there is another table called meals which will deal with the meals as a one-to-many relationship.

However, since you already started to add meals to restaurants table and we recently implement serialization, we can go further with your solution!

Delete dead code:

• meals table
• getRestaurantMeals method
• Restaurant.fromMap(), whereRestaurant.fromJson() already done the job

Make all the adjustments you need to make it work!

No need for jsonEncode() you have restaurant.toJson() method!
