Also allows top-level domain

String emailSt = 'user@sub.exämple.com';
bool isStEmailMatch = emailSt.isEmail(supportTopLevelDomain: true); //true

2. Password (Simple, Normal, Hard)

// Simple

String normalPassword = 'admin123';
bool isPasswordMatch = normalPassword.isPasswordNormal1();

// Hard
String hardPassword = 'Admin123!';
bool isPasswordMatch = hardPassword.isPasswordHard();
