Windows image to build flutter desktop apps

These windows images are based upon ltsc2019 and have have all dependencies installed to build flutter desktop apps for windows.

Create build using docker run

The images have an entrypoint script, which creates a release build of a flutter app mounted at C:\src within a container. After building the app the result is copied to C:\src\build_container.

Example

Assuming the source of a flutter app is located at C:\myapp on your system, the following command will create a windows build of it and put the result into C:\myapp\build_container.

docker run --rm -v C:\myapp:C:\src tauu/flutter-windows-builder:latest

Parameters

The following options can be specified as command line options to docker run.

• -example Build the example app of a package mounted at C:\src.
• -msix Create a msix package after building the app. This requires that the msix package has been added as a dev dependency to the app.

CI/CD build

Gitlab

The image can be used in a Gitlab CI job description to build a flutter app and provide the result build as an artifact.
