Run flutter build web or dart pub run build_runner build and put the output in another branch. An easy way to update gh-pages.

Install

$ dart pub global activate peanut

or

$ flutter pub global activate peanut

Run

$ peanut

or

$ flutter pub global run peanut

This will build your project into a temporary directory, and then it will update the local gh-pages branch with the build output.

Configuration file

peanut also supports a configuration file. Convenient if you have one-off settings you'd rather not type every time you deploy.

The peanut.yaml from this repository:

# Configuration for https://pub.dev/packages/peanut
directories:
  - example

Examples

• https://github.com/dart-lang/sample-pop_pop_win/
  • Output: https://dart-lang.github.io/sample-pop_pop_win/
  • No custom configuration.
• https://github.com/kevmoo/pubviz
  • Output: http://kevmoo.github.io/pubviz/
  • Custom peanut.yaml file to specify builder-options and example as the source directory.
• https://github.com/flutter/samples/tree/master/web
  • Output: https://flutter.github.io/samples/
  • Custom peanut.yaml file to specify builder-options, multiple source directories, and a custom post-build file.
• https://github.com/kevmoo/vote.dart/tree/master/vote_demo

Git tricks

The easiest way to push your gh-pages branch to github (without switching from your working branch) is:

$ git push origin --set-upstream gh-pages

To create (or update) your local gh-pages branch to match what's on the server.

$ git update-ref refs/heads/gh-pages origin/gh-pages

This is also useful if you want to undo a peanut run.
