tomevault-io FRB Code Generation
Note: Check your user-level
remote-testingrules before running commands. Codegen may require remote execution.
Overview
flutter_rust_bridge requires code generation when Rust APIs change. This skill maps change types to the minimal generation commands needed.
Core principle: Run only the generation commands needed for your change type.
Validation rule: If regenerated outputs cause previously green non-Generate jobs to fail, treat the generated outputs as suspect until they are validated from a clean environment.
After codegen: Check your user-level
remote-testingrules. If codegen was run remotely, pull changes back to local.
Quick Reference
| Change Type | Command |
|---|---|
Example Rust API (frb_example/**/rust/src/api/*.rs) |
./frb_internal precommit-generate |
| Flutter integrate examples | ./frb_internal precommit-integrate |
frb_codegen/ generation logic |
./frb_internal precommit-generate + generate-internal-rust |
frb_rust/src/ core API |
./frb_internal generate-internal-rust |
frb_example/pure_dart generator |
./frb_internal generate-internal-frb-example-pure-dart |
| CLI help documentation | ./frb_internal generate-internal-book-help |
Non-generated (docs, comments, tests, frb_dart/) |
No generation needed |
Important Rules
For CI diagnosis rules about generated-file format/lint failures, repeated package-level Generate drift, or Generate :: FRB Codegen :: Command Integrate failures, you MUST read frb-fix-ci first. This skill is for command selection, not CI failure-propagation diagnosis.
For pure_dart / pure_dart_pde generation issues, treat frb_example/pure_dart as the upstream source and frb_example/pure_dart_pde as the derived copy. See frb-fix-ci for the CI diagnosis workflow.
If CI repair has already entered repeated package-level drift, you MUST stop choosing narrower commands and switch to frb-fix-ci.
Do not manually patch generated files as the final fix. The final accepted result should be produced by the corresponding generation command in a clean matching environment.
