Hi@akhtar,
In your TextField, you can call one function named onChange(). You can store the value in a variable and can use it according to your use case. You can see the below example.
TextField(
       onChanged: (val) {
       pass = pass;
    },
obscureText: true,
decoration: InputDecoration(
prefixIcon: Icon(Icons.lock),
labelText: "Password",
  ),
),
