Any way to change behavior of existing keyboard shortcuts?

[dyzdyz010]

I'd like to make Ctrl + Enter to insert a new line, Enter to send the message, but it seems those 2 shortcuts already have default behaviors to create new line. Any way I can block the default behavior of existing shortcut and make it only perform the function I make it to? My code:

Widget _buildEditor(BuildContext context) {
    var quillEditor = QuillEditor(
      controller: _controller,
      scrollController: ScrollController(),
      scrollable: true,
      focusNode: _focusNode,
      autoFocus: true,
      readOnly: false,
      placeholder: 'Enter content',
      expands: false,
      maxHeight: 120,
      padding: const EdgeInsets.symmetric(vertical: 5, horizontal: 5),
      showCursor: true,

      // maxHeight: double.maxFinite,
      customStyles: textStyles,
      customElementsEmbedBuilder: customElementsEmbedBuilder,
    );

    return RawKeyboardListener(
        focusNode: FocusNode(), onKey: editorOnKeyEvent, child: quillEditor);
  }

  void editorOnKeyEvent(RawKeyEvent event) {
    // print(event.isKeyPressed(LogicalKeyboardKey.enter));
    if (!event.isAltPressed &&
        !event.isControlPressed &&
        !event.isMetaPressed &&
        event.isKeyPressed(LogicalKeyboardKey.enter)) {
      // print('Enter');
      sendButtonOnPressed();
    }
  }

If I press Enter, it should either send the content or do nothing, but with code above it inserts a new line to the content if it doesn't send properly
