Methods
-
convert<
U> (U converter(T? data)) → AsyncPhase< U> - A method that creates a new instance of the same AsyncPhase subtype with a different generic type based on the value returned by the converter.
-
copyAsWaiting(
) → AsyncWaiting< T> - A method that creates a new AsyncWaiting instance with the existing data.
-
copyWith(
T newData) → AsyncPhase< T> - A method that copies a phase to create a new instance of the same AsyncPhase subtype with the provided data.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
rethrowIfError(
) → void - A method that rethrows the error if this AsyncPhase instance is of type AsyncError.
-
toString(
) → String -
A string representation of this object.
override
-
when<
U> ({required U waiting(T data), required U complete(T data), required U error(T? data, Object e, StackTrace s), U initial(T data)?}) → 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 data)?, U waiting(T data)?, U complete(T data)?, U error(T? data, Object e, StackTrace s)?}) → 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?> (Future< T> func(), {S? fallbackData, void onComplete(T data)?, void onError(S? data, Object e, StackTrace s)?}) → 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.
