isValidFullName

Validates if this string represents a valid full name.

Validation Rules

• Must contain at least two parts (first name and last name) separated by spaces

• Each part must contain only letters (no numbers or special characters)

• Null or empty strings are considered invalid

Note: This is a basic validation. Real-world names can include:

• Hyphens (e.g., "Mary-Jane")

• Apostrophes (e.g., "O'Brien")

• Accented characters (e.g., "José", "Françoise")

• Single names (mononyms)

Adjust validation logic based on your application's requirements and target audience.

Usage Examples

// In a signup form ViewModel
fun validateFullName(name: String): Boolean {
    return name.isValidFullName()
}

// In a Composable
var fullName by remember { mutableStateOf("") }
val isValid = fullName.isValidFullName()

OutlinedTextField(
    value = fullName,
    onValueChange = { fullName = it },
    isError = fullName.isNotEmpty() && !isValid,
    label = { Text("Full Name") },
    supportingText = {
        if (fullName.isNotEmpty() && !isValid) {
            Text("Enter first and last name")
        }
    }
)

Valid Examples

• "John Doe" → true

• "Mary Jane Watson" → true (three parts is fine)

• "Alice Smith Johnson" → true

Invalid Examples

• null → false

• "" → false

• "John" → false (only one part)

• "John123" → false (contains numbers)

• "John-Doe" → false (contains hyphen - not a letter)

• "John Doe!" → false (contains special character)
