When using TextOneLine, we found all kinds of strange unicode characters when inspecting our app in appium.

When inspecting the code for TextOneLine we saw this:

String? get data => super.data == null ? null : Characters(super.data!).toList().join("\u{200B}");

why is that?

It's adding zero-width spaces between all charactes. This will force the text to be displayed in a single line.

Please see: flutter/flutter#18761

Keep in mind this widget is a temporary hack. It will be deprecated when Flutter fixes this issue.
