Methods

chain(covariant Callback4Arg<T1, T2, T3, T4>? a, covariant Callback4Arg<T1, T2, T3, T4>? b) → Callback4Arg<T1, T2, T3, T4>

Returns a strongly-typed chained callback that calls through to the two provided callbacks, a and b, in order. Useful for executing multiple callbacks where only a single callback is accepted.

override

chainFromList(covariant List<Callback4Arg<T1, T2, T3, T4>?> callbacks) → Callback4Arg<T1, T2, T3, T4>

Returns a strongly-typed chained callback that calls through to the list of provided callbacks in order. Useful for executing multiple callbacks where only a single callback is accepted.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited
