Adds a CI matrix for React Native 0.83 through 0.87. Each job runs package typecheck, build, and runtime parity tests. This ensures we stay compatible with older, supported React Native releases when updating the plugin for newer versions.

Summary by CodeRabbit

  • Bug Fixes

    • Improved Android image and accessibility prop handling across React Native versions 0.84–0.86.
    • Ensured null alt and accessible values are processed consistently with the installed React Native version.
    • Improved compatibility for images using equivalent src and source values.
  • Tests

    • Added coverage for image accessibility behavior with null-valued props.
    • Added runtime parity checks across supported React Native versions to help prevent version-specific regressions.

Walkthrough

The pull request adds React Native 0.83–0.86 parity checks and updates Android accessibility and image normalization behavior for version-specific semantics.

Changes

React Native parity

Layer / File(s) Summary
Version-specific accessibility handling
packages/react-native-boost/src/runtime/index.ts, packages/react-native-boost/src/runtime/__tests__/index.test.ts
Android accessibility handling uses version-specific null checks. Tests cover React Native 0.84 and React Native 0.85+.
Parity normalization coverage
packages/react-native-boost/src/plugin/__tests__/parity/mocks/ReactNativeFeatureFlags.ts, packages/react-native-boost/src/plugin/__tests__/parity/normalize.ts, packages/react-native-boost/src/plugin/__tests__/parity/parity.test.ts
Parity mocks include four release-default feature flags. Image normalization removes duplicated src aliases when required. Tests cover null alt and accessible props.
Cross-version CI validation
.github/workflows/test.yml
A matrix job tests React Native 0.83 through 0.86 with dependency installation, typechecking, builds, and parity tests.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 67c5b

The CI matrix improves compatibility coverage, but the parity normalization may hide a React Native 0.86 difference by removing a duplicate property unconditionally. The change is mergeable with explicit owner awareness and follow-up to restrict that normalization to the legacy versions where it applies.

Poem

A rabbit checks each RN trail,
Through null props hopping without fail.
Four flags glow beneath the moon,
Image aliases leave the room.
Matrix runners test each gate,
Parity lands in perfect state.
