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.
