Validation prompt

Use this to decide whether a fired diagnostic is real or a false positive.

The rule fires on shadowColor, shadowOffset, shadowOpacity, shadowRadius, or elevation Properties inside a JSX style or *Style inline ObjectExpression, or inside any object value passed to StyleSheet.create({...}). False positive: the project targets React Native earlier than 0.76 — boxShadow shipped in RN 0.76 (the New Architecture release) and is only fully supported from that version onward.

Fix prompt

Use this once validation confirms the diagnostic is real.

Collapse the platform-specific keys into a single boxShadow string of the form "offset-x offset-y blur spread color" (e.g. "0 2px 8px rgba(0, 0, 0, 0.1)"); multiple comma-separated shadows and the inset keyword are supported. Verify the project is on RN 0.76 or newer before deleting the iOS shadow* and Android elevation fallback. See https://reactnative.dev/docs/view-style-props#boxshadow
