signalValueLookupFn property
final
Optional callback to look up a signal's current value by wire name.
When provided (embedded/DevTools mode), the hover tooltip shows the signal value on a second line beneath the wire name. When null (standalone mode), only the wire name is shown.
Implementation
final ({String value, bool computed, String signalId})? Function(
String wireName,
)? signalValueLookupFn;
