dart pub unpack
Downloads a package and unpacks its contents in place.
Unpack is one of the commands of the pub tool.
$ dart pub unpack <package>[:<descriptor>] [--[no-]resolve] [--output=<output directory>] [--[no-]force] [other options]
This command downloads the specified <package> and
extracts its contents to a <package>-<version> directory.
For example, the following command downloads and extracts the
latest stable version of package:http from the pub.dev site,
to the current directory:
dart pub unpack http
To change the source or version of the downloaded package,
add a package descriptor
after the package name and a colon.
For example, the following command downloads the 1.2.0 release
of package:http from the pub.dev site:
dart pub unpack http:1.2.0
To learn more about configuring the dependency source, check out the documentation on package descriptors.
Options
#For options that apply to all pub commands, check out Global options.
--force or -f
#
Overwrite existing folders that conflict with the package folder or its contents during extraction.
--[no-]resolve
#
By default, dart pub get runs automatically to complete
package resolution after downloading and unpacking a package.
To disable automatic resolution,
specify the --no-resolve flag:
dart pub unpack http --no-resolve
--output=<dir> or -o <dir>
#
By default, extract the package to the current directory (.).
To change the directory the package is extracted to,
specify the desired output directory with the --output option.
For example, the following command unpacks the
1.2.0 release of package:http to the local_http_copies
directory.
dart pub unpack http:1.2.0 -o local_http_copies
