PercentProperty constructor

PercentProperty(String name, double fraction, { String ifNull, bool showName: true, String tooltip, String unit, DiagnosticLevel level: DiagnosticLevel.info })

Create a diagnostics property for doubles that represent percentages or fractions.

Setting showName to false is often reasonable for PercentProperty objects, as the fact that the property is shown as a percentage tends to be sufficient to disambiguate its meaning.

The showName and level arguments must not be null.

Implementation 

PercentProperty(String name, double fraction, {
  String ifNull,
  bool showName = true,
  String tooltip,
  String unit,
  DiagnosticLevel level  = DiagnosticLevel.info,
}) : assert(showName != null),
     assert(level != null),
     super(
  name,
  fraction,
  ifNull: ifNull,
  showName: showName,
  tooltip: tooltip,
  unit: unit,
  level: level,
);
