Properties

fv → Fu<C>

final

The hash code for this object.

no setter, inherited

keys → Fr<Iterable<K>>

late, final

runtimeType → Type

Methods

add(V item) → void

Available on Fu<List<V>>, provided by the FuCommonListX extension

call() → T

Available on Fr<T>, provided by the FrX extension

changes() → Stream<C>

"changes" is not a great name since, by contract, the stream includes the initial, not yet changed value. maybe rename it to "distinctValues()" ?
