ExecutionQueue class

A queue for sequentially executing functions one at a time.

This class ensures that functions are executed in the order they are added, with only one function running at a time. When a function is added using the add method, it is placed at the end of the queue. The queue processes each function sequentially, starting the next function only after the current one has completed. The queue continues processing until it is empty.

The add method immediately schedules the function for execution, but it does not execute it until all previously added functions have finished. This allows for accurate control over the order and timing of function execution.

You can introduce a delay before a function executes by specifying a buffer duration. This is useful for scenarios where you need to throttle execution.

Methods

add<T>(TSyncOrAsyncMapper<dynamic, T> function, {Duration? buffer}) → FutureOr<T>
Adds a new function to the queue. The function will be executed immediately after all previously added functions have completed.
addAll(Iterable<TSyncOrAsyncMapper> functions, {Duration? buffer}) → List<FutureOr>
Adds multiple functions to the queue for sequential execution. See add.
last() → FutureOr
Waits for all functions in the queue to complete, and return the result of the last function in the queue.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.

reset() → void
Resets the prev result to null.
toString() → String
A string representation of this object.
