Exception when building a non scrollable Editor

[GyuriMajercsik]

I have a use case when I need a non-scrollable read-only view of QuillEditor. It should expand as needed by the document.
I'm not sure if this is possible currently but I tried the following:

Widget quillEditor = SizedBox(
      height: 500,
      width: 500,
      child: QuillEditor(
        controller: _controller!,
        scrollController: ScrollController(),
        scrollable: false,
        maxHeight: 400,
        focusNode: _focusNode,
        autoFocus: false,
        readOnly: false,
        placeholder: 'Add content',
        expands: false,
        padding: EdgeInsets.zero,
        customStyles: DefaultStyles(
          h1: DefaultTextBlockStyle(
              const TextStyle(
                fontSize: 32,
                color: Colors.black,
                height: 1.15,
                fontWeight: FontWeight.w300,
              ),
              const Tuple2(16, 0),
              const Tuple2(0, 0),
              null),
          sizeSmall: const TextStyle(fontSize: 9),
        ),
      ),
    );

I receive the following exception:

Performing hot restart...
Syncing files to device macOS...
Restarted application in 435ms.
