10 months ago I wanted to provide a bit more detail and an example, since this seems like a significant bug/regression. After un-doing several times, it seems like I am only ever able to re-do a single event. Please let me know if I am misunderstanding the intended functionality, since it would be pretty simple to implement my own undo/redo stacks and commands if necessary. Thanks for your support!
The below demo is using the provided example repo
https://github.com/AppFlowy-IO/appflowy-editor/assets/127775585/c92f9f5f-8d0b-4449-88f1-7d442032edee

Bug Description
I cannot redo the same steps that I did undo
Add Undo / Redo buttons
final undo = MobileToolbarItem.action( itemIconBuilder: (context, __, __) => Icon( Icons.undo, color: MobileToolbarTheme.of(context).iconColor, ), actionHandler: (, editorState) { undoCommand.execute(editorState); }, );
final redo = MobileToolbarItem.action( itemIconBuilder: (context, __, __) => Icon( Icons.redo, color: MobileToolbarTheme.of(context).iconColor, ), actionHandler: (, editorState) { redoCommand.execute(editorState); }, );
How to Reproduce
1) start sample, edit text a little 2) call undo several (5-6) times 3) call redo
Expected Behavior
Expected: I can redo all undone steps Actual: I can redo 1-2 steps only
Operating System
Android, iOS
AppFlowy Editor Version(s)
2.1.0
Screenshots
No response
Additional Context
I use custom buttons with undoCommand.execute(editorState); redoCommand.execute(editorState);
