In the code example there is a very large indentation. Most likely there is a typo instead of **const SizedBox( height: 12, )**, it says **120** `// TODO: Add TextField widgets (101) // [Name] TextField( decoration: const InputDecoration( filled: true, labelText: 'Username', ), ), // spacer const SizedBox(height: 120.0), // [Password] TextField( decoration: const InputDecoration( filled: true, labelText: 'Password', ), obscureText: true, ),` <img width="1440" alt="Снимок экрана 2024-04-09 в 03 06 01" src="https://github.com/material-components/material-components-flutter-codelabs/assets/88054229/67cb29df-f766-4a39-8e00-40829e785829">
