You can view the triage session on Warp.

Here's what I found while triaging this issue:

This looks like a feature request for currently missing Dart/Flutter language support rather than a bug. The request needs clarification because "language support" could mean several different Warp surfaces or capabilities.

I have a few follow-up questions before I can narrow this down:

1. Which Warp surface are you asking about: opening/editing .dart files, notebook/code blocks, terminal completions, Agent context, or another surface?
2. What specific Dart/Flutter capability would make this useful for your workflow, such as syntax highlighting, LSP-style diagnostics/completions, or Flutter project/workflow support?

Reply in-thread with those details and the triage workflow will automatically re-evaluate the issue and update the diagnosis, labels, and next steps.

Maintainer details

I concluded that requester asks for Dart/Flutter language support, but the report does not specify which Warp surface or capability; code inspection shows Dart is not currently in the syntax-highlighting or LSP language lists..

Automated triage

Summary: This is a feature request for Dart/Flutter language support. The current report is too broad to determine whether the requested support is syntax highlighting, LSP/editor features, notebook code blocks, terminal completions, Flutter workflow integration, or Agent context handling.

Classification: Enhancement, likely area:editor-notebooks, with needs-info because the target surface and capability are not specified.

Code context: Current syntax/code language support is driven by hard-coded language lists and filename mappings in crates/languages/src/lib.rs; Dart/Flutter and .dart are absent there. LSP support in crates/lsp/src/config.rs and crates/lsp/src/supported_servers.rs currently enumerates Rust, Go, Python, JavaScript/TypeScript, C, and C++ only. Notebook code-block language choices in app/src/notebooks/editor/notebook_command.rs also do not list Dart.

Reproducibility: Unknown. The requested language appears absent from the inspected support lists, but the issue does not include a concrete workflow or expected behavior to reproduce.

Duplicate check: No likely duplicates were found among the provided recent/open issues; none describe Dart or Flutter language support.

Likely owners: @kevinyang372 for code editor/LSP language support; @bnavetta as a secondary reviewer if notebook/editor surfaces are involved.

Follow-up needed: Please clarify the Warp surface and the specific capability desired so maintainers can route and scope the request accurately.

Question reasoning

1. Which Warp surface are you asking about: opening/editing .dart files, notebook/code blocks, terminal completions, Agent context, or another surface? — Different Warp surfaces use different code paths and owners, so this determines routing and implementation scope.
2. What specific Dart/Flutter capability would make this useful for your workflow, such as syntax highlighting, LSP-style diagnostics/completions, or Flutter project/workflow support? — The report only says "language support"; maintainers need the desired capability to decide whether this is a small language-registry addition or a larger feature/spec request.

This is my automated analysis and may be incorrect. A maintainer will verify the details.
