Getting this stack trace when I create a Terminal as such:

final globalDebugTerminal = Terminal(
  maxLines: 50000,
);

I have a log that is filling this globalDebugTerminal up without having any TerminalView widget created, and then when i go and create a TerminalView widget to view the contents as such:

            TerminalView(globalDebugTerminal,
                textStyle: kDefaultTerminalStyle,
                controller: _terminalController,
                //autofocus: true,
                backgroundOpacity: _showEllet ? 0.75 : 1.0,
                onSecondaryTapDown: (details, offset) async {
              await copySelection(context);
            })

It throws the exception above.
