semanticsValue property Null safety
final
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%'.
