Minimal code example

Code sample

  /// Inside a formbuildertextfield
  validator: FormBuilderValidators.compose([
   FormBuilderValidators.url()
  ]),

Current Behavior

Upon entering a capital letter on the top level domain, the validator fails showing that the URL is invalid.
For example:
HTTPS://WWW.GOOGLE.COM - invalid link
https://www.google.com - valid link
https://WWW.GOOGLE.com - valid link
HTTPS://WWW.GOOGLE.COM - invalid link

Expected Behavior

I believe the URL should be case insensitive. Any part of it having a capital letter should not invalidate the URL
While this is my exact case I'm not sure if it's valid for everyone. If given the go-ahead I could modify the REGEX pattern to include capital letters for the top level domain.

Steps To Reproduce

1. Create a formbuildertextfield
2. add a formbuildervalidators.url as the textfield's validator
3. Run the project and try to type a url with a capital letter for the top level domain e.g. https://google.Com instead of https://google.com

@bjarn-hau yes, of course. Take a look on https://github.com/flutter-form-builder-ecosystem/.github/blob/0489089d2b364b14f41c3d5cd3ebd6f98a937a59/CONTRIBUTING.md
Thanks for that
