Cannot add new entries in Tree view - Flutter Flow

[looganxx]

return Container(
width: widget.width,
height: widget.height,
child: JsonEditor(
onChanged: (_) {},
json: jsonEncode(widget.json),
themeColor: Color(0xFF4B39EF),
));

this is my configuration

I'm able to edit the already existing values of json object, but i can't add new string, list or object.
Instead, in text visualization I can make any modification.

What am I missing?

@looganxx Have you tried the more options(3 dots) on the left side?

[looganxx]

@SanjaySodani yes, of course. I used the three dots, but when I click on String, List or others options this make no effect to the JSON content.

[SanjaySodani]

@looganxx I gave it a try and it works for me. Even on the demo app (from the package landing page).

And was the object expanded too?

[looganxx]

yes, the object expands. Even for me, the demo app works. I just wanted to know if I am doing something wrong in my implementation, because as I said, in text mode I can edit.

[SanjaySodani]

No, you are not missing anything.

[looganxx]

I am using FlutterFlow for the implementation, maybe something with it does not work well? Do you have the opportunity to test your package on FF?

[SanjaySodani]

No, I have never. Let me try it out. I will revert, it might take some time as I'm new to FF.
