Flutter Web-Only Base Image

Standalone GHCR image for Flutter web-only builds.

Our custom version after discontinuation of the CirrusLabs image.

Image tags

After pushing this directory as a repository, the publish workflow creates:

• ghcr.io/solvro/flutter-web-only:<flutter-version>

For this app, use for example:

FROM ghcr.io/solvro/flutter-web-only:3.44.1 AS build

Versioning

The pinned Flutter stable version lives in versions.env as FLUTTER_STABLE_VERSION.

The scheduled updater checks the latest Flutter stable release and opens a PR that updates versions.env. Merging that PR triggers the publish workflow and pushes a new specific version tag.

Contents

This image installs Flutter from the official Flutter git tag and pre-caches only web artifacts. It does not include the Android SDK, Java runtime, or Android command-line tools.
