isolate_manager 5.0.0-rc.6

Create multiple long-lived isolates for a function (keep it active to send and receive data), supports Worker and WASM on the Web.

5.0.0-rc.6

• Export the IsolateState.
• Update the CHANGELOG to show the migration guide.

5.0.0-rc.4

• Bring the isolate_contactor to this package and make it lighter and easier to maintain.
• Update the tests.
• Remove unneeded platforms in the example.

5.0.0-rc.3

• Remove deprecated methods.
• Improve the IsolateManager.create behavior (use a new customFunction).
• Imptove the type of the customFunction and workerFunction.

5.0.0-rc.2

• Update README.
• Update homepage for beta version.

5.0.0-rc.1

• Bump sdk to ^3.3.0.
• Remove autoInitialize parameter.
• Remove deprecated methods.
• MIGRATION: All Worker's MUST be re-compiled
  • If you're using the IsolateManagerFunction.workerFunction, you need to re-generate the JS for the Web Worker (compile from Dart to JS). The IsolateManagerFunction.customFunction will be automatically applied.
  • If you're using the old method, you need to send a initialized signal from an Isolate and a Worker:

    • Custom function of an Isolate: add the controller.initialized(); to the end of the function.

      • Before:

        void customFunction(dynamic params) {
          final controller = IsolateManagerController(params);
          controller.onIsolateMessage.then((value){
            // ...
          });
        }
        

      • After:

        void customFunction(dynamic params) async {
          // Do something sync or async here
        
          final controller = IsolateManagerController(params); 
          controller.onIsolateMessage.then((value){
            // ...
          });
        
          controller.initialized(); // <--
        }
        

    • On the Web Worker: add jsSendMessage(IsolateState.initialized.toJson()); to the end of the main method.

      • Before:

        void main() {
          callbackToStream('onmessage', (MessageEvent e) {
            return js_util.getProperty(e, 'data');
          }).listen((message) {
            // ...
          });  
        }
        

      • After:

        void main() async {
          // Do something sync or async here
        
          callbackToStream('onmessage', (MessageEvent e) {
            return js_util.getProperty(e, 'data');
          }).listen((message) {
            // ...
          });
        
          jsSendMessage(IsolateState.initialized.toJson()); // <--
        }
        

4.3.0

• Support WASM.
• Add benchmark tests.
• Deprecate the IsolateFunctionHelper in favor of the IsolateManagerFunction.
• Improve the IsolateManagerFunction.workerFunction.
• [Experiment and Optional] Able to send an initialized signal from the isolate to the main app to ensure that the isolate is ready to receive the messages from the main app. The Migration Steps:
  • Step 1:

    • If you're using the IsolateManagerFunction.workerFunction, you need to re-generate the JS for the Web Worker (compile from Dart to JS). The IsolateManagerFunction.customFunction will be automatically applied.

    • If you're using the old method, you need to send a initialized signal from an Isolate and a Worker:

      • Custom function of an Isolate: add the controller.initialized(); to the end of the function.

        • Before:

          void customFunction(dynamic params) {
            final controller = IsolateManagerController(params);
            controller.onIsolateMessage.then((value){
              // ...
            });
          }
          

        • After:

          void customFunction(dynamic params) async {
            // Do something sync or async here
          
            final controller = IsolateManagerController(params); 
            controller.onIsolateMessage.then((value){
              // ...
            });
          
            controller.initialized(); // <--
          }
          

      • On the Web Worker: add jsSendMessage(IsolateState.initialized.toJson()); to the end of the main method.

        • Before:

          void main() {
            callbackToStream('onmessage', (MessageEvent e) {
              return js_util.getProperty(e, 'data');
            }).listen((message) {
              // ...
            });  
          }
          

        • After:

          void main() async {
            // Do something sync or async here
          
            callbackToStream('onmessage', (MessageEvent e) {
              return js_util.getProperty(e, 'data');
            }).listen((message) {
              // ...
            });
          
            jsSendMessage(IsolateState.initialized.toJson()); // <--
          }
          

    • Step 2: Update the create and createCustom method:

      • Before:

      final isolate = await IsolateManager.create(
        function, 
        workerName: 'function',
      );
      

      • After:

      final isolate = await IsolateManager.create(
        function, 
        workerName: 'function',
        autoInitialize: false, // <--
      );

2.1.2

• The method .start() is now optional, the plugin will automatically call this method when using .compute for the first time, so you have 3 way to create the instance:

  1. Basic usage:

  IsolateManager<int> isolateManager = IsolateManager.create(
    fibonacci,
    concurrent: 4,
  );
  
  await isolateManager.start();
  

  2. Use start without await:

  IsolateManager<int> isolateManager = IsolateManager.create(
    fibonacci,
    concurrent: 4,
  );
  
  isolateManager.start();
  

  3. Use start when creating the instance:

  IsolateManager<int> isolateManager = IsolateManager.create(
    fibonacci,
    concurrent: 4,
  )..start();
