eslint-plugin-lingui tried to access typescript error

Describe the bug
After upgrading eslint-plugin-lingui from 0.8.1 to 0.9.0 I get the following error:

ESLint: 8.57.1

Error: Failed to load plugin 'lingui' declared in '.eslintrc.json': eslint-plugin-lingui tried to access typescript, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.

Required package: typescript

Expected behavior
No error

Additional context
React 17

Thanks for the report. Indeed we have added TypeScript support. I was not aware that this was not a listed dependency before. But indeed it is only in dev-dependencies.

I see that our no-unlocalized-strings rule is using types from the typescript package but does not import and functional stuff from it... – at least this was my first thought but indeed TypeFlags is a helper object for checking the flags property in our code.

I don't think it's a good idea to implement the functionality without using the official constants (e.g. replicating it)... as we already have @typescript-eslint/utils in our dependencies it's probably a good idea to add the base typescript package as well... what do you guys think?

I tried a fix here: #98 - this should fix your issue @nmoinvaz

It still does not fix it in 0.11.0.

Oops! Something went wrong! :(

I took a look at #98 and I don't see where typescript is added to your package.json. Can you add it to your dependencies, while still allowing it to load to conditionally (which I assume is what you were trying to do)?
