🗣️ Golden Tests in Flutter
Speaker: Mara Felismino
Golden testing is a method of testing the appearance of your widget, by firstly generating a snapshot of your widget’s UI and then by continuously comparing it to follow-up snapshots every time you re-run your tests, to check both snapshots look the same (regressions tests). The main advantages of golden testing are not just to let you know what has changed in terms of UI of your widget but to also quickly let you see the appearance of your widget without having to run the app on a device. On the negative side, golden tests can be quite challenging to setup/config in existing/larger projects and how to properly integrate them with a CI/CD solution.

🗣️ .Net expat in Dart land
Speaker: Rui Craveiro
With Dart having been turned by Flutter into a nearly universal language for the frontend, its use on the backend is the last frontier left to conquer to make it a fully universal language. One of the most important examples of missing or incomplete APIs is database connectivity, one example being the connectivity between Dart and MongoDB. Although there is a package for Dart precisely to solve this problem, that same package has limitations, such as not supporting sessions and transactions. Instead of investing in understanding the existing package, the communication protocol that is used with MongoDB and potentially wasting a lot of time on a solution that would not be guaranteed to be viable, the solution adopted was to use an official package, maintained by MongoDB itself, but implemented in Go. The big challenge was to find an easy way to communicate between Dart and Go via FFI, which is a C interface. The solution found was to use Protocol Buffers in order to facilitate this communication. As a result, not only the package mongo_go was developed, but also two packages, go_bridge and dart_bridge created to facilitate the reuse of the technique in other contexts. An example of a second package developed with the same technique is firebase_go_admin.
