hello @AhmedAmineZr,

1. Always allow entering 0, even when the number starts with a +, to support users who make mistakes.

3. For the refactoring, create a form_fields folder and put everything inside it. The shared files will be called FormField.

form_fields/
  text_input/
    text_input.dart
  phone_number/
    phone_number_input.dart

4. We are getting this error:

======== Exception caught by services library ======================================================
The following assertion was thrown during method call TextInputClient.updateEditingState:
Range start 17 is out of text of length 8
'package:flutter/src/services/text_input.dart':
Failed assertion: line 1130 pos 7: 'range.start >= 0 && range.start <= text.length'

5. In the initial settings, the country selector is enabled with enabled = true by default.
