@srkrishnan1989 Please provide the minimum code to reproduce the problem.

create fresh app using "flutter create -t skeleton my_app"

just replace code using styled_text on "sample_item_list_view.dart" file

replace this code
title: Text('SampleItem ${item.id}'),

with

title: StyledText(
                text: '<b>SampleItem ${item.id}</b>',
                tags: {
                  'b': StyledTextTag(
                      style: TextStyle(fontWeight: FontWeight.bold)),
                },
              ),

change items list length to 30 count, now run the app,

click gear icon on appbar and change system theme to dark and go back,

now scroll
