Regex for Email Validation in Kotlin

val emailRegex = "^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}\$".toRegex()

}

• Explanation:
• val emailRegex = "^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}\$".toRegex(): This line defines the regular expression pattern for validating an email address. It uses the toRegex() function to create a regex object from the specified pattern.
• fun isEmailValid(email: String): Boolean { ... }: This function takes an email address as input and returns a boolean value indicating whether the email is valid or not.
• return emailRegex.matches(email): The function uses the matches function of the regex object to check if the input email matches the defined pattern, and returns the result as a boolean value.
