buildAppImage function

Future<void> buildAppImage({ required String repoRoot, required ArtifactPayload payload, required AppImageConfig config, required String outputPath, required String arch, required String appImageToolPath, })

Builds an AppImage from a prebuilt payload.

Implementation

  // source extension instead of being forced to one format.
