isPassword property

bool get isPassword

Checks if the string is a valid password.

A valid password must:

• Be at least 8 characters long.
• Contain at least one alphabetic character.
• Contain at least one digit.
• Contain at least one special character from the set !@#\$%^&*= (excluding spaces).

Example:

var password = 'P@ssw0rd';
print(password.isPassword); // Outputs: true

Returns true if the string meets all password criteria, otherwise false.

Implementation

bool get isPassword {
  if (length < 8) {
    return false;
  }

  RegExp alphaExp = RegExp(r'[a-zA-Z]');
  RegExp digitExp = RegExp(r'\d');
  RegExp specialExp = RegExp(r'[!@#\$%\^&\*=]');
  if (!alphaExp.hasMatch(this) ||
      !digitExp.hasMatch(this) ||
      !specialExp.hasMatch(this)) {
    return false;
  }

  return true;
}
