How to get a Source for a given File now that .createSource is deprecated?

[dark...@gmail.com]

Hello!

I'm trying to migrate away from File.createSource, and was wondering how to get a Source instance (for the sake of creating an ErrorReporter)

The depreciation notice mentions using the analysis result. But the thing is, I'm trying to get a Source for possibly non-dart files. In which case, I don't want to analyze those files.

As such, how could I get a Source?

Thanks!

  You can instantiate `FileSource` directly, it is an API now.

  Theoretically (not now yet), you don't need to provide `Source` for `ErrorListener` or `ErrorReporter`.

  Or `AnalysisError`.

  They all are bound to some file, but it should happen externally, e.g. `LibraryAnalyzer`, see `UnitAnalysis`.
