Code generation with Source_gen (Dart Package of the Week #6)

Today's package of the week brings us to the source_gen package. This package allows us to automate code generation in Dart projects, and is the go-to recommendation by the Dart team. Also includes a mini-tutorial on the json_serializable package (Watch till the end!)

How do I handle package imports and generics correctly with Annotation- and normal Generators?

[JeanMerelis]

Thanks, very useful.
I need to generate a single file in the lib folder based on all classes of the application with a certain annotation. What would be the procedure for me to achieve this result?

Can ppl read the source code of these packages like in PHP?

Hello, it wasn't working for me and wasn't generating example.g.dart at 6:20. (maybe due to new version of the packages). I solved this by modifying my_generators/build.yaml.

You should write
build_extensions: { ".dart": [".info.g.part"] }
instead of
build_extensions: { ".dart": [".info.part"] }
