Problem

I was working on an app targeted for Germany. And in German locale 12.5 is written 12,5, 1.050 in German means one thousand and fifty.

Solution

I created 2 utility functions 1st to parse double to de locale and second to convert back to double.

Here is the code

import 'package:intl/intl.dart'; static String deFormat (String val) { final deFormat = NumberFormat.decimalPattern('de',); return deFormat.format(double.parse(val)); } static num enFormat (String val) { final deFormat = NumberFormat.decimalPattern('de',); return deFormat.parse(val); } 

You'll need intl package.
