semanticsValue property

String semanticsValue
final

The Semantics.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 value expressed as a percentage, i.e. 0.1 will become '10%'.
