Methods
-
copyAsWaiting(
) → AsyncWaiting< T> - A method that creates an AsyncWaiting object based on the phase that this method is called on.
-
copyWith(
T newData) → AsyncPhase< T> - A method that copy a phase to create a new phase with new data.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.
override
-
when<
U> ({required U waiting(T?), required U complete(T), required U error(T?, Object?, StackTrace?), U initial(T?)?}) → U - A method that returns a value returned from one of callback functions corresponding to the current phase of an asynchronous operation.
-
whenOrNull<
U> ({U initial(T?)?, U waiting(T?)?, U complete(T)?, U error(T?, Object?, StackTrace?)?}) → U? - A method that returns a value returned from one of callback functions corresponding to the current phase of an asynchronous operation.
Operators
-
operator ==(
Object other) → bool -
The equality operator.

Static Methods
-
from<
T extends Object?, S extends T?> (FutureOr< T> func(), {S? fallbackData, void onComplete(T)?, void onError(S?, Object, StackTrace)?}) → Future<AsyncPhase< T> > - A method that runs an asynchronous function and returns either AsyncComplete with the function result as data or AsyncError with the error information, depending on whether or not the function completed successfully.
