Padding numbers in integer picker

[insin]

Would it be possible to add some configuration for integer pickers to zero-pad the numbers displayed in the generated list items?

I have a dialog widget which uses a pair of NumberPicker.integers to select minutes and seconds and gives you back a Duration object, which currently looks like this:

It would be nice to be able to pad the numbers less than 10 out with a zero so they match the way minutes and seconds are displayed elsewhere in the app, e.g. 00 : 09 in the example above.

A quick fix (even though it is a really bad habit to change library files) is to change line 281 to child: new Text(value.toString().padLeft(2, '0'), style: itemStyle), inside _integerInfiniteListView(). The values will be stored without the padding 0, so you will have to take care of that as well.
