My database model is

import 'package:hive_flutter/hive_flutter.dart';
part 'transactions.g.dart';

@HiveType(typeId: 1)
class Transactions {
  @HiveField(0)
  final int id;

  @HiveField(1)
  final String title;

  @HiveField(2)
  final int amount;

  @HiveField(4)
  final DateTime dateTime;

  @HiveField(5)
  bool isIncome;

  Transactions(
      {required this.id,
      required this.title,
      required this.amount,
      required this.dateTime,
      required this.isIncome });
}

i want to delete with @HiveField(0) final int id;

CodePudding user response：

await db.add(data);

This will auto-generate a key for you. If you want to use your key, you actually have to do so:

await db.put(data.id, data);
