Help: How can I disable rounding?

[SamMotta]

I need to ignore de fourth decimal place:

It formats: 0.0325 => 0.033
But I need to format to: 0.032

final numberFormat = NumberFormat('0.000', 'pt_BR');
return numberFormat.format(this);

I would recommend using the floor method before passing the number to the number formatter, as package:intl does not offer rounding options.
