feat: add FormBuilderCupertinoDateTimePicker

Connection with issue(s)

Close #3

Solution description

Pulled the source code from https://github.com/flutter-form-builder-ecosystem/flutter_form_builder/blob/main/lib/src/fields/form_builder_date_time_picker.dart and converted all the material dependencies to cupertino. Removed undefined fields and had to pull a few of the types/enums/defs into the repo to avoid material dependency. The only exception to this is the TimeOfDay class, which has had some unfavorable discussions about making it agnostic.

@deandreamatias any plans to merge this? Would be ideal to depend on a published version instead of my fork..

[deandreamatias]

@charlieforward9 really sorry, I didn't seen this before. I need to activate notification for new PR on this repo.

Please take a look on conflicts. When resolve, I will run de the pipeline and merge if is all ok

@deandreamatias done

[charlieforward9]

@deandreamatias I am not sure what else needs to be done here but I just had to bump intl on my fork and include that in here as well so it would be really nice to see this merged in so I can depend on the official package. Thank you.

Looks like some formatting issue was thrown in the action and then something related to errorBuilder overriding an updated Flutter FormField API. Not sure if this is on all channels. I am on Flutter master channel.

I can attempt to contribute to this fix soon if you'd like, but I'm looking for some improved communication.

[deandreamatias]

I need find a solution to build with stable and beta flutter versions on parallel branches, because the current pipeline implementation has the issue that can't use different intl versions.
Give me some days and I will find how solve this.

[deandreamatias]

I'm working on solution for flutter versions. See flutter-form-builder-ecosystem/flutter_form_builder#1486
After validate there, I will copy on this repo

@charlieforward9 please update your branch with the new code on main. Thanks!
