        child: SingleChildScrollView(
          padding: EdgeInsets.all(24),
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              Icon(Icons.lock, size: 100, color: Colors.blueAccent),
              SizedBox(height: 20),
              Text("Welcome Back!", style: TextStyle(fontSize: 28, fontWeight: FontWeight.bold)),
              SizedBox(height: 30),
              _buildTextField("Email", false),
              SizedBox(height: 15),
              _buildTextField("Password", true),
              SizedBox(height: 10),
              Align(
                alignment: Alignment.centerRight,
                child: TextButton(
                  onPressed: () {}, 
                  child: Text("Forgot Password?")
                ),
              ),
              SizedBox(height: 20),
              ElevatedButton(
                onPressed: () {},
                child: Padding(
                  padding: EdgeInsets.symmetric(horizontal: 60, vertical: 15),
                  child: Text("Login", style: TextStyle(fontSize: 18)),
                ),
              ),
              SizedBox(height: 25),
              Row(
                mainAxisAlignment: MainAxisAlignment.center,
                children: [
                  Text("Don’t have an account? "),
                  GestureDetector(
                    onTap: () {},
                    child: Text("Sign Up", style: TextStyle(color: Colors.blue)),
                  ),
                ],
              )
            ],
          ),
        ),
      ),
    );
  }

  Widget _buildTextField(String hint, bool isPassword) {
    return TextField(
      obscureText: isPassword ? _obscureText : false,
      decoration: InputDecoration(
        labelText: hint,
        border: OutlineInputBorder(borderRadius: BorderRadius.circular(12)),
        suffixIcon: isPassword
            ? IconButton(
                icon: Icon(
                  _obscureText ? Icons.visibility_off : Icons.visibility,
                ),
                onPressed: () {
                  setState(() {
                    _obscureText = !_obscureText;
                  });
                },
              )
            : null,
        filled: true,
