For example, to format all the Dart files in or under the current directory, you would run: “` $ dart format . “` You can also specify multiple files or directories by providing a space-delimited list: “` $ dart format lib bin/updater.dart “`

Q: How can I prevent `dart format` from overwriting my original files?

By default, `dart format` overwrites the original files. To prevent this, you can use the `–output` or `-o` flag. For instance, to see the formatted contents without overwriting the files, use: “` $ dart format -o show bin/my_app.dart “` Alternatively, to see which files would change without making any changes, use: “` $ dart format -o none bin/my_app.dart “`

Q: How do I configure the line length for the formatter?

The default line length is 80 characters, but you can configure it. You can add a `formatter` section to the `analysis_options.yaml` file at the root of your project: “` formatter: page_width: 123 “` This setting will apply to all files in the package. Alternatively, you can override this setting for individual files by adding a marker comment at the top of the file: “` // dart format width=123 “`

Q: What formatting changes does `dart format` make?

`dart format` makes several formatting changes, including: – Removing unnecessary whitespace. – Wrapping every line to 80 characters or shorter (or the configured line length). – Adding trailing commas to argument or parameter lists that span multiple lines and removing them from ones that don’t. – Possibly moving comments before or after a comma.

Q: How can I check which files would be changed by `dart format` without actually changing them?

To see which files would be changed without making any changes, you can use the `–output none` flag along with `–set-exit-if-changed`: “` $ dart format -o none –set-exit-if-changed bin/my_app.dart “` This command will return an exit code of 1 if changes are needed and 0 if no changes are needed.

Q: Can I customize the `dartfmt` tool for specific needs?

While the standard `dartfmt` tool is highly configurable through the `analysis_options.yaml` file, if you need more customized formatting, you can modify the `dart_style` package.
