 - Include custom test utilities, mocks, or constants
 - Add custom comments or documentation to generated files
 
-**Important**: When `customHeaders` are provided, the default imports (`import 'package:flutter/material.dart';` and `import 'package:flutter_test/flutter_test.dart';`) are **not** automatically included in feature files, and the default `import 'package:flutter_test/flutter_test.dart';` is not included in step files. You have full control over what imports and content are added to your generated files.

 The custom headers will be added to:
 - **Feature files**: After any data table imports, replacing the default flutter/material and flutter_test imports
 - **Step files**: After any data table imports, replacing the default flutter_test import
