type missmatch int <-> double

[EvsenevDev]

I have model with these fields:

final double price;
final double tax;

@ColumnInfo(name: 'exchange_rate')
final double exchangeRate;

And these columns in database:

generated code:
price: row['price'] as double

Issue:
type 'int' is not a subtype of type 'double' in type cast

I'm guessing sometimes in mappper recognizes it as int sometimes as double.

Is it possible to map it as I need?
Maybe converter where I can get Object? as input and map by myself?
I've tried to use String converter, but it's using as String instead of toString() which works fine.

Any solution?
