Make padding adjustable.

[slavap]

Currently padding is hardcode, and actually it is a little bit excessive by default, i.e. padding: EdgeInsets.all(10.0),
Please make it adjustable.

Hello @slavap ,

Thanks for the suggestion. It is indeed not flexible at the moment. However, the workaround explained here usually solves the padding questions:
icemanbsi#35

Please pet me know if that works for you too.

@lcuis I think that using transform: Matrix4.translationValues(-10,0,0), for just adjusting padding is overkill and hack :-) Please add normal way to define it.

Well, as I said, this is a workaround. So, yes, it may be that one day, a better way to handle padding with search_choices will exist.

@lcuis sure, as workaround it is ok.

I believe this was solved by #27 .
Feel free to reopen if needed.
