Create zip via `dart2native` command with a "bootstrap" file as executable
Since 2.6.0 Dart release we can use dart2native
to build the AWS function executable.
Still waiting for cross platform compilation (which would allow to build our AWS Dart Lambda on any build system).
Right now I am focusing on getting compilation done via docker linux container - I also may consider running a AWS instance to do the compile job in cloud - but that seems like repeating the CI tool.
When I get more time I explore CI tools integrations and I hope meanwhile we get the Dart cross-compile fixed - link here: https://github.com/dart-lang/sdk/issues/28617
