Flutter GH Pages

Automates the build and deployment of your Flutter web app on Github gh pages

Action

To use this action, create an action like the following on your workflows folder

name: Gh-Pages

on:
  push:
    branches: [ main ]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4
      - uses: subosito/flutter-action@v2
      - uses: bluefireteam/flutter-gh-pages@v7

To build a project in a folder other that the root, use the workingDir property

      ...
      - uses: bluefireteam/flutter-gh-pages@v7
        with:
          workingDir: example

By default, the action will use the auto setting for web renderers, to change that you can use the webRenderer property.

More on web renderers here: https://flutter.dev/docs/development/tools/web-renderers

      ...
      - uses: bluefireteam/flutter-gh-pages@v7
        with:
          webRenderer: canvaskit

By default, the action will send the files to the gh-pages branch, which is the default used by Github Pages. If you need to change that, the targetBranch property can be used

      ...
      - uses: bluefireteam/flutter-gh-pages@v7
        with:
          targetBranch: my-gh-pages-branch

By default, the generated page only works on User or Organization sites ex:user.github.io/. You can change that by specifying the baseHref argument, so the site will work on a Project Site, ex:user.github.io/repoName.

The parameter baseHref must start and end with a forward slash "/". (For projects created on flutter version earlier than 2.5.0, please manually edit the file web/index.html, changing the line <base href="/"> to <base href="$FLUTTER_BASE_HREF">)

      ...
      - uses: bluefireteam/flutter-gh-pages@v7
        with:
          baseHref: /my-repo/

To pass arguments to the builder with --dart-define the customArgs property can be used

      ...
      - uses: bluefireteam/flutter-gh-pages@v7
        with:
          customArgs: --dart-define="simple=example"

And consumed in the code via (const is mandatory!):

void main() async {
  String arg = const String.fromEnvironment('simple'); // arg = "example"
  ...
}

To use github pages with a custom domain, add a file named CNAME to the <project>/web folder whose contents is your domain, like:

subdomain.domain.com
