Allow reading & updating reanimated shared values from other workout threads #5642

Open hannojg opened 9 months ago

hannojg commented 9 months ago

Description

When trying to update a REA shared value from another workout thread, such as from react-native-worklets-core, you're getting errors, that you aren't allowed to read or update values:

Reading from `_value` directly is only possible on the UI runtime.

CleanShot 2024-02-06 at 10 33 04@2x

Steps to reproduce

  1. Setup a new react native app
  2. Install react-native-reanimated and react-native-worklets-core
  3. Setup their babel plugins
  4. In App.tsx create a new REA useSharedValue
  5. Try to update that value from a workless-core "worklet" function, such as created by Worklets.createRunInContextFn or useWorklet
