AFAIK this logic was used as a workaround for preventing the TextInput component from automatically gaining focus when releasing the touch after scrolling. However, this solution no longer works due to the use of the gesture handler library via the GestureDetector component (reference).

@geriux I pushed some changes for addressing the feedback in previous comments, so the PR is ready for another review, thanks 🙇 . NOTE: I've also updated the PR's description to include videos using the dark mode. |

I wonder if this should have the .current value as a dependency instead?

I think that's not really necessary because we're accessing the reference (i.e. scrollViewRef.current). Although the function is memoized, while scrollViewRef doesn't change, the reference retrieved by current` property will have the latest value.
Actually, I'm thinking that most likely we even don't need to add the references (i.e. scrollViewRef) in the dependency list, since React guarantees their inmutability. I'll remove scrollViewRef from here and do the same on the rest of the callbacks.

I've applied the change referenced in the previous comment in d66fb3d
References can be omitted from the dependencies arrays since React guarantees that they are inmutable.

Now it will enabled in the following cases: - The block doesn't have inner blocks. This applies to root blocks and nested blocks without further nested blocks. - Blocks with nested blocks if the block is selected. - Blocks with nested blocks if none of the nested blocks is selected. * Update Podfile.lock * Update react-native-editor changelog * Fix text block query locator in Android E2E tests * Fix Cover block E2E test * Fix Spacer block E2E test Co-authored-by: Gerardo Pacheco <gerardo.pacheco@automattic.com>

BlockDraggablecomponent for enabling dragging blocks.Why?
This component is required for providing the drag & drop functionality for blocks, similarly as we have in the web version.
How?
Based on the logic of the same component on the web version, this component handles the following functionality:
Draggableblock to determine when a block is being dragged, as well as finding via the blocks layouts theclientIdof the block.Testing Instructions
Drag a block
Drag a block partially off of scroll view
NOTES: Sometimes text blocks might interfere with the long-press gesture. I haven't found yet a solution for this, but I'd like to note that this should be addressed before releasing the drag&drop feature.
HTML editor
Due to a recent conflict with the gesture handler library, the HTML editor has been updated hence, it would be nice to check that it works as expected.
