Just make sure that the id property from your model is the same as the key returned by box.add and you should be good to go.

When you call box.put it actually takes in the key of your data.

If you're using a model that extends HiveObject, you can use the key getter instead of id in box.put:

final favorite = Favorite(/* [ ... ] */);
await favoriteBox.put(favorite.key, favorite);

Otherwise, if you're using a list, you can get the key for your data through box.keyAt(index).

Dear can give an example for my problem i am not using a list so i dont
have the index there.

I have a details page and an add to favorites button when i click that
button i need to add a some details to list and show it list view when i
add it again its duplicating the data i dont want to duplicate just need to
update if there is same item.

i think you get my point.

Could you please post the code for your Favorite model? And if possible, the code where you add favorites to the box.

mbaumgartenbr on 31 Dec 2020

It's my Model Class

import 'package:hive/hive.dart';part
'favorite.g.dart';@HiveType(typeId: 1)class Favorite {  @HiveField(0)
final int id;  @HiveField(1)  final String name;  @HiveField(2)  final
String place;  @HiveField(3)  final String image;  @HiveField(4)
final int reviews;  Favorite(this.id, this.name, this.place,
this.image, this.reviews);}

*------Adapter*


part of 'favorite.dart';//
**************************************************************************//
TypeAdapterGenerator//
**************************************************************************class
FavoriteAdapter extends TypeAdapter<Favorite> {  @override  final
typeId = 1;  @override  Favorite read(BinaryReader reader) {    var
numOfFields = reader.readByte();    var fields = <int, dynamic>{
for (var i = 0; i < numOfFields; i++) reader.readByte():
reader.read(),    };    return Favorite(      fields[0] as int,
fields[1] as String,      fields[2] as String,      fields[3] as
String,      fields[4] as int,    );  }  @override  void
write(BinaryWriter writer, Favorite obj) {    writer
..writeByte(4)      ..writeByte(0)      ..write(obj.id)
..writeByte(1)      ..write(obj.name)      ..writeByte(2)
..write(obj.place)      ..writeByte(3)      ..write(obj.image)
..writeByte(3)      ..write(obj.reviews);  }}

Here i have a list of my products from list i push to details page of
the products here there is a add to favorite button, when i press that
button it will call this function

 favoriteBox.add(Favorite(id, name,place,featuredImage,rating,));

when i click that button again its adding the same item 2 time. here i
need to update that item if its already in that box.

Its is my first time with flutter and hive so please kindly help for
this. hopw you will understand my things

Thank you

Sure! So.

I would suggest you to read through the documentation on hive, it will help a lot.

As your model doesn't extend HiveObject, you will have to find the key of your Favorite class iterating through box.values:

/// Make sure you test if the favorite exists before running this function
Future<void> updateItemById(Box<Favorite> box, int id) async {
  final boxEntries = box.values.toList();

  // Find your favorite by its id
  final favorites = boxEntries.where((fav) => fav.id == id).toList();

  if (favorites.isEmpty) return; // favorite not in the box

  // Get the index of your favorite in the box
  final favIndex = boxEntries.indexOf(favorites.first);

  // Update the instance
  await box.putAt(favIndex, favorite);
}

An easier way of doing the same thing is using the HiveObject mixin in your model, just add with HiveObject to the definition of Favorite:

// Make sure you run build_runner if you make this change
class Favorite with HiveObject {
  // your code
}

Then you will be able to use the methods delete, save and the key getter:

final favorite = Favorite(id: 0);

favoriteBox.add(favorite);

// Update any field thats not final
favorite.id = 1;

await favorite.save(); // updates the favorite without adding a new entry to the box

// If you dont want to mutate the object, you can use `favorite.key`
final oldFavorite = Favorite(id: 0);
final newFavorite = Favorite(id: 1);

await box.put(oldFavorite.key, newFavorite); // use the old key to override the entry with a new Favorite

Then, before adding a new favorite you can check if it exists, and update it accordingly.

mbaumgartenbr on 1 Jan 2021

Brother here my question is how can i check it is exist or not.

Oh!

Make sure your model extends HiveObject. Then use the isInBox getter:

Take a look at HiveObject. It helps a lot.

Another way:

final boxList = box.values.toList();
final isInBox = boxList.contains(favorite);

// OR

final favorite = Favorite(id: 0);
final isInBox = box.values.where((fav) => fav.id == favorite.id);
// You can also use .firstWhere()

Hope this time I understood you. Let me know if it worked 🙂

You cannot have a class inside a @HiveType that doesn't have an adabter. (Hive only supports primitive types, like String, int, Map, List, ..., all other types must be registered)

For your approach to work you would either have to make CompletedHistoryRecord into a @HiveType and use a Hive List to save it inside History or use methods like toMap() and fromMap() to save a Dart Map of your data models inside History.

mbaumgartenbr on 3 Jan 2021

For simplicity you can add @HiveType annotation to your model to fix the issue.

@HiveType(typeId: 3)
class UpComingHistoryRecord {
...

Yes you can! But you have to register an adapter for it:

@HiveType(typeId: 5 /*any int < 255 here. Look out for duplicates*/);
class CompletedHistoryRecord {
  CompletedHistoryRecord({this.id, this.name});

  // Mark the properties you want to store with @HiveField(). For example:
  @HiveField(0)
  final int id;

  @HiveField(1)
  final String name;

  // [ ... ] Other properties and methods
}

And do the same for the UpComing model.
Then run build_runner again and register the adapters.

Another way is changing the History model to store maps instead of your models:

@HiveField(0)
final List<Map<String, dynamic>> _upComingHistoryRecord;

// And

@HiveField(1)
final List<Map<String, dynamic>> _completedHistoryRecord;

Then when you instantiate History do it like so:

final history = History(
  [completedHistoryRecordInstance.toJson()],
  [upComingHistoryRecordInstance.toJson()],
);
// Use the instances, or a list with the instances:
final history = History(
  listOfCompletedHistoryRecord.map((value) => value.toJson()).toList(),
  listOfUpComingHistoryRecord.map((value) => value.toJson()).toList(),
);

Then in History, add getters for converting back:

List<CompletedHistoryRecord> get completedHistoryRecord {
  return _completedHistoryRecord.map((value) => CompletedHistoryRecord.fromJson(value)).toList();
}

// Do the same for UpComing

Seems like an error with the package path_provider. I would recommend that you use Hive.initFlutter() from the hive_flutter package as it resolves the paths for you 🙂

import 'package:hive_flutter/hive_flutter.dart';

void main() async {
  await Hive.initFlutter();
  // [ ... ]
}

Hive.initFlutter already calls WidgetsFlutterBinding.ensureInitialized(), so you don't have to.
Oh, and make sure you add hive_flutter: ^0.3.1 as a dependency.

Try the following:

Stop your app
Run flutter clean
Run flutter pub cache repair
Run flutter pub get
Start your app again

Let me know if this works!

How can i retrieve this list in another class

Another way is changing the History model to store maps instead of your
models:

@HiveField(0)final List> _upComingHistoryRecord;
// And
@HiveField(1)final List> _completedHistoryRecord;

Then when you instantiate History do it like so:

final history = History(
[completedHistoryRecordInstance.toJson()],
[upComingHistoryRecordInstance.toJson()],
);// Use the instances, or a list with the instances:final history = History(
listOfCompletedHistoryRecord.map((value) => value.toJson()).toList(),
listOfUpComingHistoryRecord.map((value) => value.toJson()).toList(),
);

Then in History, add getters for converting back:

List get completedHistoryRecord {
return _completedHistoryRecord.map((value) => CompletedHistoryRecord.fromJson(value)).toList();
}
// Do the same for UpComing

Actually the error tells "NoSuchMethodError: The getter 'upComingHistoryRecord' was called on null." which means History object that you're trying to retrieve upComingHistoryRecord property from is null. I'm not sure but it might worth checking if history object is null or not before getting properties.

History history; does not instantiate nor have any reference to an object, you just created a null variable, try like so:

final historyList = historyBox.values.toList();
final history = historyList.first; // same as calling list[0]
final a = history.completedHistoryRecord;

Unfortunately dart is not good at handling generic types like List<Map<String, dynamic>>. It's not related to hive itself but dart.

You can store List<dynamic> then cast it to Map<dynamic, dynamic> then cast items into <String, dynamic>.

Unfortunately dart is not good at handling generic types like List dynamic>>. It's not related to hive itself but dart.

You can store List then cast it to Map then
cast items into .

Could you try to modify your class like that:

@HiveType(typeId: 2)
class History extends HiveObject{
  @HiveField(0)
  final List<dynamic> _upComingHistoryRecord;
  @HiveField(1)
  final List<dynamic> _completedHistoryRecord;

  History(
      this._upComingHistoryRecord,
      this._completedHistoryRecord,
      ) : assert(_upComingHistoryRecord != null,
'_upComingHistoryRecord cannot be null.'),
        assert(_completedHistoryRecord != null,
'_completedHistoryRecord cannot be null.');


  List<UpComingHistoryRecord> get upComingHistoryRecord {
    return _upComingHistoryRecord.map((value) =>
UpComingHistoryRecord.fromJson(value as Map<String, dynamic>)).toList();
  }

  List<CompletedHistoryRecord> get completedHistoryRecord {
    return _completedHistoryRecord.map((value) =>
CompletedHistoryRecord.fromJson(value as Map<String, dynamic>)).toList();
  }
}

Try this for the getters:

List<CompletedHistoryRecord> get completedHistoryRecord {
  final output = Map<String, dynamic>[];
  _completedHistoryRecord.forEach((value) {
    final historyRecord = value as Map<dynamic, dynamic>;
    output.add(historyRecord as Map<String, dynamic>);
  });
  return output;
}

Do the same for UpComing.

Btw, your problem is not with Hive anymore, the errors you're getting are from dart...

Thanks for helping me. really from the bottom of my heart.

I just created a separate model and loaded it.

but we should find a proper way for these situations.

Thanks for your help with everything.

Note : I am not going to stop texting you guys.
