bolter 3.2.5

Simplest mutable state manager, listen what ever u want, and run your state mutators in defaultBolter.runAndUpdate method

Bolter

This repository a listener-notification mechanism for monitoring changes in values.

Features

• Listen to changes in values by providing a Getter function and a BolterNotification function.
• Notify listeners only when the result of calling the Getter function has changed.
• Optionally notify listeners either globally or for a specific BolterNotification based on whether an exactNotification was provided.

Usage

To use the Bolter, you need to create an instance of the Bolter class and call its methods as needed.

final bolter = Bolter();

bolter.listen(
() => myValue,
() => print('Value has changed!'),
);

bolter.shake();

bolter.runAndUpdate(
action: () => doSomething(),
afterAction: () => print('Action is complete!'),
);

bolter.stopListen(() => print('Value has changed!'));

bolter.clear();

Performance

The performance of the _SyncBolter class is generally acceptable for a moderate number of listeners. The code caches the hash code of the result of calling the Getter functions, which helps to avoid unnecessary calls and improve performance. However, if the number of listeners becomes very large, or the Getter functions are expensive to compute, the performance may become an issue and additional optimizations may be necessary. The code includes a kProfileBolterPerformanceLogging flag, which can be used to log the time taken for notifying all listeners and assist with profiling the performance of the code.
