PasswordTextFormField

This a custom text form field that validates the password. It is recommended to use this field instead of the default text form field. It has the option to show which requirements have been met and which have not. The default password validation section can also be overwritten by supplying a function that returns a Widget.

Usage:

PasswordTextFormField(
  controller: passwordController,
  overrideValidationRow: true,
  customValidationSection: customValidationSection,
  decoration: InputDecoration(
    border: InputBorder.none,
  ),
  autovalidateMode: AutovalidateMode.onUserInteraction,
  showValidationRow: true,
)

Override Custom Validation Section

Supply a function that returns a Widget that will be displayed in the validation section.

Structure Of The Function

Widget customValidationSection({
  required bool hasEightCharacters,
  required bool hasCapitalLetter,
  required bool hasSmallCapsLetter,
  required bool hasADigit,
  required bool hasASpecialCharacter,
}) {
