Escaping Chaos: Strategies to Move from Polyrepo to Monorepo

In this talk, we'll go through a real-life case of a large banking app developed by 60+ Flutter developers that started as a polyrepo project, with each Dart package being placed in a separate Git repository.

As the project grew, this became more and more problematic. The development workflow started being painful, and the main branch was broken most of the time, with developers spending more time solving conflicts and figuring out how to correctly merge all their PRs rather than focusing on delivering actual business value.

We're going to analyze all the pain points that we suffered and see how the polyrepo approach compares with monorepo in Flutter projects. Then I'll show you the strategy we took to execute the migration. As we couldn't afford just to hold the development completely to clean everything up, we had to develop a smarter strategy that allowed for a more seamless transition.
