isPasswordValid

Validates if this string meets password complexity requirements.

Current Requirements

At least one digit (0-9)
At least one lowercase letter (a-z)
Length between 8 and 20 characters

Note: Adjust the regex pattern if you need different requirements (uppercase, special chars, etc.).

Usage Examples

// In a ViewModel - validate password on signup
fun validatePassword(password: String): PasswordValidation {
    return when {
        password.isEmpty() -> PasswordValidation.Empty
        !password.isPasswordValid() -> PasswordValidation.Weak
        else -> PasswordValidation.Valid
    }
}

// In a Composable - show password strength
var password by remember { mutableStateOf("") }
val isValid = password.isPasswordValid()

OutlinedTextField(
    value = password,
    onValueChange = { password = it },
    isError = password.isNotEmpty() && !isValid,
    supportingText = {
        if (password.isNotEmpty() && !isValid) {
            Text("Password must be 8-20 chars with a digit and lowercase letter")
        }
    }
)

Valid Examples

"password1" → true (8+ chars, has digit and lowercase)
"myp4ssword" → true
"test1234567890" → true

Invalid Examples

null → false
"" → false
"short1" → false (< 8 chars)
"password" → false (no digit)
"12345678" → false (no lowercase letter)
"verylongpasswordwithmorethan20characters1" → false (> 20 chars)

Receiver

String? The password string to validate (can be null).

Return

true if the password meets complexity requirements, false otherwise.
