RegexForm class

A Form that knows when all its RegexTextFields and RegexUIs are valid: enable the submit button with onChanged or RegexForm.isValidOf. When one field changes, the others are checked again too, so "repeat password" follows the password. Fields with optional: true may stay empty. Plain TextFormFields are not counted; Form.validate() still checks them.

RegexForm(
  onChanged: (ok) => setState(() => canSubmit = ok),
  child: Column(children: [
    RegexTextField.email(),
    RegexTextField.password(),
  ]),
)
