Insert with autoIncrement() id error

[mytc]

I have a table like this:

class Metas extends Table {
  IntColumn get id => integer().autoIncrement()();
  TextColumn get key => text()();
  TextColumn get value => text()();
}

I am using DOA to insert the data
Future insertMeta(Insertable<Meta> mt) => into(metas).insert(mt);

Problem when I try to insert with it:

var meta = Meta(
id:0,
  key:'key 1',
 value:'meta value',
);
doa.InsertMeta(meta );

I got this:
SqliteException (SqliteException(1555): UNIQUE constraint failed: metas.id, constraint failed (code 1555))

The reason seem to be the id value, but since it is autoincrement, and required at the same time, there is no way I can initial the class with null.

Does it mean, I can't use DOA to insert data? Instead, I should write own query statement for it?

Generated data classes are meant to hold a full row in a table. For inserts, you may only need partial data (e.g. to skip the columns with default values). Moor generates companion classes for this purpose:

doa.InsertMeta(MetaCompanion.insert(key: 'key 1', value: 'meta value'));
