indicatorSemanticsValue property
The SemanticsProperties.value for this progress indicator.
This will be used in conjunction with the semanticsLabel by
screen reading software to identify the widget, and is primarily
intended for use with determinate progress indicators to announce
how far along they are.
For determinate progress indicators, this will be defaulted to
ProgressIndicator.value expressed as a percentage, i.e. 0.1 will
become '10%'.
