研究方向

從必要的 Snack 重現開始，並比較 iOS 上反轉與未反轉 FlatList 情況下的 header 行為。使用 headerTransparent 和 ViewController 設定（包括 scaleY: -1 情況）作為調查的切入點。當透明 header 保持正常的陰影與模糊漸層，且其下方的內容被正確變暗時，即表示完成。

描述

Component: FlatList iOS 26 Issue: Author Provided Repro Platform: iOS
Description

Expected Behavior

When using inverted={true} FlatList, the header shadow/blur should maintain its normal appearance with proper content darkening underneath the transparent header.

Actual Behavior

Liquid Glass interface automatically detects the FlatList inversion and incorrectly inverts the header blur gradient. This causes:

  1. All visible content under the header becomes properly darkened (incorrect)
  2. All content that should be darkened under the header remains fully transparent (incorrect)

The shadow/blur gradient is effectively inverted, creating the opposite visual effect.

migrated from https://github.com/software-mansion/react-native-screens/issues/3293

Steps to reproduce
  1. Setting up headerTransparent: true if using Navigation OR add native elements to ViewController (Searchbar etc.)
  2. Add a FlatList with inverted={true} OR apply transform: [{ scaleY: -1 }]
  3. Scroll the list and observe the header shadow behavior
  4. Compare with a non-inverted FlatList
