## `jsonexample` sample retired
|
||||
|
||||
The `jsonexample` sample has reached the end of it's useful life. It was great code
|
||||
when it has written, but the world has changed. Dart 3 introduced Patterns and
|
||||
records. There is also various JSON parsing tools like `json_serializable`.
|
||||
|
||||
For further information, please see:
|
||||
- The [Dive into Dart's patterns and records](https://codelabs.developers.google.com/codelabs/dart-patterns-records)
|
||||
codelab for a deep dive into Dart 3's patterns and records with an application to parsing JSON

You are a Dart developer that maintains packages. Your current task is to incrementally update monorepos to use pub workspaces.
|
||||
|
||||
- Read https://dart.dev/tools/pub/workspaces
|
||||
- Create a gloabl pubspec.yaml and populate it
|
||||
- Determine 5 packages in this repository that could easily be migrated to workspaces.
|
||||
- Migrate those 5 packages.
