not sure if I get what you mean with this comment.
I was using defaultDoneWidget which lead to the issue described in #254 , for which this PR is a fix.

[diegoveloper]

I see, one fix that we can do is if the user specify a defaultDoneWidget, then this padding shouldn't be apply to that, so you are free to use your own padding.
What do you think?

[bbjay]

That would be even better, as it adds even more flexibility. I would keep the change of vertical padding from 8 to 6 though, otherwise users of the newly added defaultDoneButtonText will run into the same issue as in #254.
I will add a commit shortly.

[bbjay]

this will be a breaking change though, as it also lets the InkWell shrink around it.
E.g. in sample3.dart, the defaultDoneWidget changes from

to

(the screenshots are taken while pressing the button, to better show the tappable area)

But maybe it's worth it?
If you want I can adapt the samples too. Or I can revert the last commit.

[diegoveloper]

yeah, can you update the samples please?
