You can also find out how strong a password is

// Measure the strength of the password
print(estimateStrength('123456')); // PasswordStrength.weak

print(estimateStrength('slcjreiuvmk')); // PasswordStrength.weak

print(estimateStrength('KEURIBVJKIUYER')); // PasswordStrength.weak

print(estimateStrength('setgf784156')); // PasswordStrength.good

print(estimateStrength('euhnvHHJGkjhjk')); // PasswordStrength.good

print(estimateStrength('fYjV')); // PasswordStrength.weak

print(estimateStrength('fhjTYRxs48hgRT')); // PasswordStrength.good

print(estimateStrength('pN47bT')); // PasswordStrength.weak

print(estimateStrength('hjfR^f87984L;&gh')); // PasswordStrength.strong

// Measure the strength of generated passwords
print(estimateStrength(generatePassword()));
// PasswordStrength.good

print(estimateStrength(generatePassword(upperCase: true)));
// PasswordStrength.weak

print(estimateStrength(generatePassword(punctuation: true)));
// PasswordStrength.strong

print(estimateStrength(generatePassword(punctuation: true, digits: true)));
// PasswordStrength.strong

print(
  estimateStrength(
    generatePassword(
      length: 15,
      punctuation: true,
      digits: true,
    ),
  ),
); // PasswordStrength.strong
