Patch Information

Library Name: react-native-performance

Patch Number: 002
Patch Description: fix-listeners-memory-leak
Full Patch Filename: react-native-performance+5.1.4+002+fix-listeners-memory-leak.patch

Patch Details

Reason for Patch

This patch is part of memory leak audit.
react-native-performance has a memory leak where ReactMarker listeners are not properly removed when the module is destroyed. Additionally, setupListener can be called multiple times when getPackages is called multiple times, causing duplicate listeners.

Changes Made

This PR mainly improves how listeners are added and removed. It also extracts lambdas into constants so that they can be consistently referenced when calling addListener and removeListener, preventing duplicate listeners and ensuring that listeners can be properly removed.
