Allow decoration: null

[LizDresserDev]

I started converting some of our TextField() widgets into AutoSizeTextField() widgets. In our TextField() widgets, we allowed for a null decoration like this:

                Flexible(
                  child: TextField(
                    controller: _dateOrTaskNameController,
                    decoration: null,
                  ),
                ),

Simple conversion to AutoSizeTextField() looks like this:

                Flexible(
                  child: AutoSizeTextField(
                    controller: _dateOrTaskNameController,
                    decoration: null,
                  ),
                ),

The exception is below:

I/flutter ( 6673): ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════ I/flutter ( 6673): The following NoSuchMethodError was thrown building LayoutBuilder: I/flutter ( 6673): The getter 'prefixText' was called on null.

Could we get the AutoSizeTextField widget to have the same decoration handling as the TextField widget?

Thanks @LizDW I will need to dig more into the issue. Keep you posted. It will be good if you can help dig into the source code and take look as well.
