This is from the coverage step of the workflow on a PR: https://coveralls.io/builds/67179524 This is the overall result you get if you click on a coverage badge: https://coveralls.io/builds/67179061 Note that...

This will be possible once native assets doesn't require an experimental flag. - [x] Remove all the flutter infra and deps from package:objective_c - [x] Add build.dart infra instead -...
