passwordValidations method

String passwordValidations({ int? min, int? max, required String emptyMsg, required String minLengthMsg, required String maxLengthMsg, })

Performs validations on a password string based on provided parameters.

Returns an error message indicating any validation failures, or an empty string if the password passes all validations.

Parameters:

• emptyMsg: The error message to return if the password is empty.
• minLengthMsg: The error message to return if the password is shorter than the minimum allowed length.
• maxLengthMsg: The error message to return if the password is longer than the maximum allowed length.

Example:

String error = passwordValidations(
  emptyMsg: 'Password cannot be empty',
  minLengthMsg: 'Password must be at least 6 characters long',
  maxLengthMsg: 'Password cannot exceed 12 characters'
);

Note: This function internally uses other validation functions such as isEmpty, isMinLengthValid, and isMaxLengthValid.

Example:

String error = passwordValidations(
  emptyMsg: 'Password cannot be empty',
  minLengthMsg: 'Password must be at least 6 characters long',
  maxLengthMsg: 'Password cannot exceed 12 characters'
);

Implementation

String passwordValidations({
  int? min,
  int? max,
  required String emptyMsg,
  required String minLengthMsg,
  required String maxLengthMsg,
}) {
  String error = "";
  NexValidationsFunctions functions = NexValidationsFunctions();
  if (functions.isEmpty(this)) {
    error = emptyMsg;
  } else if (functions.isMinLengthValid(this, min: min)) {
    error = minLengthMsg;
  } else if (functions.isMaxLengthValid(this, max: max)) {
    error = minLengthMsg;
  }
  return error;
}
