Add is one of the commands of the pub tool.
$ dart pub add [dev:]<package>[:<constraint>] [[dev:]<package>[:<constraint>]... ] [options]
This command adds the specified packages to the pubspec.yaml
as dependencies,
and then retrieves the dependencies to resolve pubspec.yaml
.
The following example command is equivalent to
editing pubspec.yaml
to add the http
package,
and then calling dart pub get
:
$ dart pub add http
Version constraint
By default, dart pub add
uses the
latest stable version of the package from the pub.dev site.
For example, if 0.13.3 is the latest stable version of the http
package,
then dart pub add http
adds
http: ^0.13.3
under dependencies
in the pubspec.
You can also specify a constraint or constraint range:
$ dart pub add foo:2.0.0
$ dart pub add foo:'^2.0.0'
$ dart pub add foo:'>2.0.0 <3.0.1'
If dart pub add <package>:<constraint>
is an existing dependency,
it will update the constraint.
Dependency override
To specify a dependency override, add the override:
prefix and
include a source descriptor.
For example: To override all references to package:foo
to use version 1.0.0
of the package,
run the following command:
$ dart pub add override:foo:1.0.0
This adds the override to your pubspec.yaml
file:
dependency_overrides:
foo: 1.0.0
Dev dependency
The dev:
prefix adds the package as a dev dependency,
instead of as a regular dependency.
$ dart pub add dev:foo # adds newest compatible stable version of foo
$ dart pub add dev:foo:^2.0.0 # adds specified constraint of foo
$ dart pub add foo dev:bar # adds regular dependency foo and dev dependency bar simultaneously
Previously the -d, --dev
option:
$ dart pub add --dev foo
Source descriptor
The YAML descriptor syntax allows you to add multiple packages from different sources, and apply different options and constraints to each.
$ dart pub add [options] [dev:]<package>[:descriptor] [[dev:]<package>[:descriptor] ...]
The syntax reflects how dependencies are written in pubspec.yaml
.
'<package>:{"<source>":"<descriptor>"[,"<source>":"<descriptor>"],"version":"<constraint>"}'
The descriptor
syntax cannot be used in conjunction with any of the optional
arguments it replaces. Their new, corresponding YAML sources are listed below.
git
Adds a git dependency.
$ dart pub add 'foo:{"git":"https://github.com/foo/foo"}'
You can specify the repository, and the branch or commit, or exact location, within that repository:
$ dart pub add 'foo:{"git":{"url":"../foo.git","ref":"branch","path":"subdir"}}'
url
Depends on the package in the specified Git repository.
Previously the --git-url=<git_repo_url>
option:
$ dart pub add http --git-url=https://github.com/my/http.git
ref
With url
, depends on the specified branch or commit of a Git repo.
Previously the --git-ref=<branch_or_commit>
option:
$ dart pub add http --git-url=https://github.com/my/http.git --git-ref=tmpfixes
path
With url
, specifies the location of a package within a Git repo.
Previously the --git-path=<directory_path>
option.
hosted
Adds a hosted dependency that depends on the package server at the specified URL.
$ dart pub add 'foo:{"hosted":"my-pub.dev"}'
Previously the --hosted-url=<package_server_url>
option.
path
Adds a path dependency on a locally stored package.
$ dart pub add 'foo:{"path":"../foo"}'
Previously the --path=<directory_path>
option.
sdk
Adds a package from the specified SDK source.
$ dart pub add 'foo:{"sdk":"flutter"}'
Previously the --sdk=<sdk_name>
option:
$ dart pub add foo --sdk=flutter
Options
For options that apply to all pub commands, see Global options.
--[no-]offline
By default, pub connects to the network
to retrieve hosted packages (--no-offline
).
To use cached packages instead, use --offline
.
For details,
see Getting while offline.
-n, --dry-run
Reports which dependencies would change, but doesn’t change any.
--[no-]precompile
By default, pub precompiles executables
in immediate dependencies (--precompile
).
To prevent precompilation, use --no-precompile
.
