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 is false.

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 is debug
  • lib/config.release.dart: source file to use if mode is release
  • web/sample.jpg: target file (binary)
  • web/sample.debug.jpg: source file to use if mode is debug
  • web/sample.release.jpg: source file to use if mode is release

In pubspec.yaml, add the transformer and specify the target files

- replace_content:
    - lib/config.dart
    - web/sample.jpg

After this transformer runs, the output will contain

  • lib/config.dart: contains the content of lib/config.debug.dart
  • web/sample.jpg: contains the content of web/sample.debug.jpg
