CombineWorker class abstract

Combine Worker is a pool of CombineIsolates that efficiently executes tasks in them. It is primarily used to reduce the number of isolates and provide more performant and easy way to execute tasks.

In comparison to Fluter's compute method which creates an isolate each time it's called, Combine Worker creates a pool of isolates and efficiently reuses them. At the same time, it has all of the advantages of CombineIsolate, allowing you to work with platform channels in an isolate.

If you want to create a single CombineIsolate, take a look at Combine.

Methods

close({bool waitForRemainingTasks = false}) → Future<void>
Closes the current Worker. CombineWorker is a singleton but under the hood it uses a worker manager instance which can be closed and recreated. It may be useful if you want to cancel all running and awaiting tasks (i. e. on user logout).
execute<T>(Task<T> task) → Future<T>
Executes given task in combine isolate.
executeWith2Args<T, Q, C>(Task2<T, Q, C> task, Q argument, C argument2) → Future<T>
Executes given task with given argument and argument2 in combine isolate.
executeWith3Args<T, Q, C, A>(Task3<T, Q, C, A> task, Q argument, C argument2, A argument3) → Future<T>
Executes given task with given arguments in combine isolate.
executeWith4Args<T, Q, C, A, B>(Task4<T, Q, C, A, B> task, Q argument, C argument2, A argument3, B argument4) → Future<T>
Executes given task with given arguments in combine isolate.
executeWith5Args<T, Q, C, A, B, D>(Task5<T, Q, C, A, B, D> task, Q argument, C argument2, A argument3, B argument4, D argument5) → Future<T>
Executes given task with given arguments in combine isolate.
executeWithApply<T>(TaskApply task, List positionalArguments, [Map<Symbol, dynamic>? namedArguments]) → Future<T>
Executes given task with given arguments in combine isolate.
executeWithArg<T, Q>(Task1<T, Q> task, Q argument) → Future<T>
Executes given task with given argument in combine isolate.
initialize({int? isolatesCount, int tasksPerIsolate = defaultTasksPerIsolate, WorkerInitializer? initializer, String isolatesPrefix = defaultIsolatePrefix}) → Future<void>
Initializes worker.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

operator ==(Object other) → bool
The equality operator.
