Dart: default gitignore? - dart

Question

I created a new app and the Dart Editor (M4) created a slew of files and folders. Now I'm not sure which I can safely put in the gitignore. Here's the tree:
app/.buildlog
app/build.dart
app/packages/analyzer_experimental
app/packages/args
app/packages/browser
app/packages/csslib
app/packages/html5lib
app/packages/js
app/packages/logging
app/packages/meta
app/packages/pathos
app/packages/source_maps
app/packages/unittest
app/packages/web_ui
app/pubspec.lock
app/pubspec.yaml
app/web/app.css
app/web/app.dart
app/web/app.html
app/web/out/app.css
app/web/out/app.dart
app/web/out/app.dart.map
app/web/out/app.html
app/web/out/app.html_bootstrap.dart
app/web/out/packages
app/web/out/xclickcounter.dart
app/web/out/xclickcounter.dart.map
app/web/packages
app/web/xclickcounter.dart
app/web/xclickcounter.html
I assume the following files can be ignored:
app/.buildlog
app/packages/*
app/web/out/*
app/web/packages
Is that correct?

Answer 1

From What Not to Commit on dartlang.org:
# files and directories created by pub
.dart_tool/
.packages
.pub/
build/
pubspec.lock # Except for application packages
# API documentation directory created by dartdoc
doc/api/
# files and directories created by other development environments
*.iml # IntelliJ
*.ipr # IntelliJ
*.iws # IntelliJ
.idea/ # IntelliJ
.DS_Store # Mac
# generated JavaScript files
*.dart.js
*.info.json # Produced by the --dump-info flag.
*.js # When generated by dart2js. Don't specify *.js if your
# project includes source files written in JavaScript.
*.js_
*.js.deps
*.js.map

Answer 2

Don’t commit the following files and directories created by pub, Dart Editor, and dart2js:
packages/
pubspec.lock // Except for application packages
.project
.buildlog
*.js_
*.js.deps
*.js.map
Don’t commit files and directories dropped by other development environments. For example:
.project // Eclipse
*.iml // IntelliJ
*.ipr // IntelliJ
*.iws // IntelliJ
.idea/ // IntelliJ
.DS_Store // Mac
Avoid committing generated JavaScript files:
*.dart.js

Dart default
.packages # mapping file from package names to local path
packages # until `--no-package-symlinks` is the default
build/ # contains the output of `pub build`
.pubspec.lock # controversial - Dart guideline is to only commit
# for applications but not for packages
.pub/ # cache files generated by `pub`
# .pub was moved to .dart_tool/.pub
build The new https://github.com/dart-lang/build package introduces a
.dart_tool/
directory which should be excluded.
When it comes to generated files it is generally best to not submit them to source control, but a specific Builder may provide a recommendation otherwise.

.idea # IntelliJ, WebStorm

/bazel-*
.bazelify
packages.bzl

An up to date sample Dart .gitignore is available in the gitignore repo on Github:
https://github.com/github/gitignore/blob/master/Dart.gitignore
Note that this does not contain IDE or editor files, just Dart files. You can find IDE and editor .gitignores in the same repo.
I include doc/api in my .gitignore. I tend to write substantial documentation comments and I like to use dartdoc to generate the documentation for review.
