Summary

  • Wires up the native fabricCreateViewTransitionInstance call in createViewTransitionInstance which will create a ShadowNode for old pseudo element
  • Extracts tag allocation logic into a shared allocateTag() function exported from ReactFiberConfigFabric
    • Imports allocateTag in ReactFiberConfigFabricWithViewTransition
    • Reuses allocateTag() in createInstance and createTextInstance instead of inline tag incrementing
  • Wires up native fabricSuspendOnActiveViewTransition call in suspendOnActiveViewTransition which suspends another view transition when the previous one is not yet finished

Test plan

  • Existing Fabric renderer tests should continue to pass
  • ViewTransition instance creation now properly allocates a tag and calls the native module

@zeyap
Extract allocateTag and wire up createViewTransitionInstance in Fabric
6dd9de2
Extract the tag allocation logic into a shared `allocateTag()` function
in ReactFiberConfigFabric and use it in both `createInstance`/`createTextInstance`
and `createViewTransitionInstance` in the ViewTransition config. Also wire up
the native `fabricCreateViewTransitionInstance` call.

Summary
  • Wires up the native fabricCreateViewTransitionInstance call in createViewTransitionInstance which will create a ShadowNode for old pseudo element
  • Extracts tag allocation logic into a shared allocateTag() function exported from ReactFiberConfigFabric
    • Imports allocateTag in ReactFiberConfigFabricWithViewTransition
    • Reuses allocateTag() in createInstance and createTextInstance instead of inline tag incrementing
  • Wires up native fabricSuspendOnActiveViewTransition call in suspendOnActiveViewTransition which suspends another view transition when the previous one is not yet finished
Test plan
  • Existing Fabric renderer tests should continue to pass
  • ViewTransition instance creation now properly allocates a tag and calls the native module
@zeyap
Extract allocateTag and wire up createViewTransitionInstance in Fabric
6dd9de2
Extract the tag allocation logic into a shared `allocateTag()` function
in ReactFiberConfigFabric and use it in both `createInstance`/`createTextInstance`
and `createViewTransitionInstance` in the ViewTransition config. Also wire up
the native `fabricCreateViewTransitionInstance` call.

Summary
  • Wires up the native fabricCreateViewTransitionInstance call in createViewTransitionInstance which will create a ShadowNode for old pseudo element
  • Extracts tag allocation logic into a shared allocateTag() function exported from ReactFiberConfigFabric
    • Imports allocateTag in ReactFiberConfigFabricWithViewTransition
    • Reuses allocateTag() in createInstance and createTextInstance instead of inline tag incrementing
  • Wires up native fabricSuspendOnActiveViewTransition call in suspendOnActiveViewTransition which suspends another view transition when the previous one is not yet finished
Test plan
  • Existing Fabric renderer tests should continue to pass
  • ViewTransition instance creation now properly allocates a tag and calls the native module
@zeyap
Extract allocateTag and wire up createViewTransitionInstance in Fabric
6dd9de2
Extract the tag allocation logic into a shared `allocateTag()` function
in ReactFiberConfigFabric and use it in both `createInstance`/`createTextInstance`
and `createViewTransitionInstance` in the ViewTransition config. Also wire up
the native `fabricCreateViewTransitionInstance` call.
