likes where()?

where allows you to emit changes based on a boolean condition of the incoming value, with select you can create a new value listenable that can emit a different type and at a different pace that the original one, because no matter how many times the source change that the returned notifier only emit when the selected value change compared with the previous emitted value

It's similar to BlocSelector of the flutter_block library.
