Is there a reason to completely remove the default line for androidExportType, instead of doing default: ''?

[AndrewKahr]

I'm not sure exactly how inputs works. I'm relying on it not being defined to know whether to prioritize over the app bundle parameter. If '' counts as undefined then it can be added as default.

@davidmfinol Is it preferred to have an empty string default? I can see about changing the logic to support that.

[davidmfinol]

I think it would be better to have to the empty string default, so that it is consistent with how we are defining all the other inputs.

[AndrewKahr]

Should be aligned with the other inputs now @davidmfinol
