Navigate to Editor Code Style Dart.

While there might be limited options to customize the code style, ensure that the line width is appropriately set.

Utilize Dart Formatter Tools:

You can use dartfmt command in the terminal to format your code. This ensures that your code complies with Dart's formatting standards.

Use Extensions for Enhanced Formatting:

Consider using extensions that may give you more control over your format, such as Flutter or Dart specific plugins in your IDE.

Final Thoughts

By following these guidelines, you should be able to maintain clean and readable Dart code within Android Studio. Consistent formatting is crucial for collaboration and maintaining your code in the future. If you still encounter more significant issues, exploring community forums or engaging with Dart’s official documentation can provide further insights.

With this information at hand, you can improve your workflow and enjoy a much more pleasant development experience in Flutter. Happy coding!
