Problem (one or two sentences)

Currently, in a Flutter project, the .dart files are completely ignored while indexing the codebase.
This renders the semantic search almost useless for a Flutter project.

Context (who is affected and when)

All the users that have a Flutter project and any other dart projects.

Desired behavior (conceptual, not technical)

The semantic search to properly work in Flutter projects.

Constraints / preferences (optional)
