name	frb-feature-flag
description	Use when adding or testing flutter_rust_bridge feature flags, especially flags that require coverage for both enabled and disabled states or should have package-level config plus item-level #[frb(...)] overrides.

FRB Feature Flags

Use this skill when adding a feature flag, changing a feature flag, or writing coverage for a feature flag.

API Surface

For feature flags requiring coverage for both enabled and disabled states:

• Expose the flag in flutter_rust_bridge.yaml.
• Expose the flag in the command-line interface.
• Prefer adding an item-level #[frb(...)] override when the behavior can reasonably be scoped to a Rust item.

Test Coverage

In frb_example/pure_dart, prefer tests that use the item-level #[frb(...)] override so enabled and disabled cases are both exercised in the same package.

Do not rely only on package-level config differences when both states can be covered clearly with item-level Rust APIs.
