replace_content #
replace_content
is a pub transformer that replaces the contents of some
target files with the contents of matching source files based on the
transformation mode.
Given a target file path/to/file.ext
, its content will be replaced with
the content of path/to/file.{mode}.ext
where {mode}
is the
transformation mode passed to pub serve
and pub build
.
path/to/file.{mode}.ext
and other files of the same path format will be
excluded from the rest of the build process.
The transformer has two parameters
targets
: a list of target files or a single target file.keep_source
: whether source files should be kept. Default isfalse
.
Usage #
Suppose that your project supports two transformation modes debug
and
release
, and you want to change the contents of two target files based on
the transformation mode. Those files are
lib/config.dart
web/sample.jpg
Your project should have these files
lib/config.dart
: target file (text based)lib/config.debug.dart
: source file to use if mode isdebug
lib/config.release.dart
: source file to use if mode isrelease
web/sample.jpg
: target file (binary)web/sample.debug.jpg
: source file to use if mode isdebug
web/sample.release.jpg
: source file to use if mode isrelease
In pubspec.yaml
, add the transformer and specify the target files
transformers:
- replace_content:
targets:
- lib/config.dart
- web/sample.jpg
After this transformer runs, the output will contain
lib/config.dart
: contains the content oflib/config.debug.dart
web/sample.jpg
: contains the content ofweb/sample.debug.jpg
