dart format
Use the dart format
command to replace the whitespace in your program
with formatting that follows
Dart guidelines.
This is the same formatting that you can get
when using an IDE or editor that has Dart support.
Provide a list of files or directories to the dart format
command.
For example, here’s how to format all the Dart files
in or under the current directory:
$ dart format .
To specify multiple files or directories,
use a space-delimited list.
The following command formats all Dart files under the lib
directory,
plus one Dart file under the bin
directory:
$ dart format lib bin/updater.dart
If you don’t want to overwrite the files,
add the --output
or -o
flag.
Use -o show
or -o json
to get the contents of the formatted files,
or -o none
to see only which files would change.
$ dart format -o show bin/my_app.dart
To make the command have an exit code of 1
if any formatting changes occur,
add the --set-exit-if-changed
flag.
This exit code is often used with continuous integration (CI)
to indicate that a check should fail.
$ dart format -o none --set-exit-if-changed bin/my_app.dart
For information on additional command-line options,
use the dart help
command or see the documentation for the
dart_style package.
