Allow specific subscribing, and handling internal errors * Add error handling example to example application * Added isDirty property. Added factory shorthands for current specific primary property types * Export CurrentClonable * Update example view model to use new shorthand factory * Added calculated isDirty getter to CurrentViewModel * Add tests for isDirty prop * Add docs to new BusyStatusChanged event * Current Text Controller (#19) * Implemented controller. Fixed vm reset not clearing busy status. * Added CurrentTextController to Example project * Fix type check on date time controller * Fix default value, and hash equality assignments and checks * Updated text field carrot snapback to select text when backspacing on a non-null field * Fix date time asString when cant be parsed. added tests for other supported types * Fix issue when resetting view model or using setMultiple manually. add test * Update example. Added missing test. * Clean up * Make example page scrollable * Add seperate custom and any state change listener * Add seperate custom and any error event listeners * Fix issue where lists and maps marked as dirty on initial set. * Fixed an issue where calling resetAll on the view model behaved differently for lists and maps * Report prop name and hash on list/map change. report inserted item instead of whole list. added tests * Optionally allow external / parent widget to handle viewmodel lifecycle. * Fix issue where setMultiple always issued notifications, even if nothing actually changed. * Update value equality implementation. This fixes issues with map keys, and odd comparison results.

This pull request introduces the new
CurrentTextControllerintegration to the example counter app and adds comprehensive exception handling for text controller usage. It also improves the synchronization between UI text fields and the underlyingCurrentPropertyvalues, and clarifies the distinction between standard and current-aware text controllers in the UI. Additionally, internal changes enhance property change tracking and ViewModel reset behavior.CurrentTextController Integration & UI Enhancements:
CurrentTextController.string()for thenamefield inCounterPage, binding it to thenameproperty in the ViewModel using theCurrentTextControllersLifecycleMixin. This keeps the text field in sync with the property automatically. (example/lib/counter_page.dart[1] [2]CurrentTextControllerand standardTextEditingController. (example/lib/counter_page.dart[1] [2]current_text_controller.dartfrom the main library so it can be used externally. (lib/current.dartlib/current.dartR9)ViewModel and Property Improvements:
nameproperty toCounterViewModeland ensured it is included in the list of current properties, so it participates in state management.
