an_viewmodel

• ViewModel.useHostLifecycle now supports custom onCleared state handling.

• Migration Guide: Please migrate your initialization logic from onCreate to the newly introduced onCreated method.

• Added ViewModelCallbacks to observe the ViewModel lifecycle.

• AsyncData migrated to the an_async_data package.

• Update readme.

• Added ViewModel.useHostLifecycle

• Code standardization

• Optimize the search efficiency of ViewModelProvider

• Added support for specifying the type during creation to enable runtime ViewModel instantiation.

• Upgrading Dependencies.

• RefViewModelProvider now supports handling viewModelStore removal.

• Fix the bug in the ViewModel extension viewModels.

• Fix the bug when viewModelProviderProducer is null.

• Adjust example

• Add onCreate method to ViewModel, called after the ViewModel is created.
• Add a viewModels extension method in ViewModel to retrieve ViewModels stored at the same level or higher levels.
• Add to remember the ViewModelProviderProducer when creating the ViewModel, ensuring the same behavior for subsequent automatic creations.

• Fix the bug of clearing the ViewModel when removing from ViewModelStore.

• Print logs for ViewModel creation and cleanup in non-release mode.

• Upgrading Dependencies.

• ViewModel adds extensions: valueNotifier, valueNotifierAsync, valueNotifierStream, valueNotifierAsyncStream, valueNotifierFuture, valueNotifierAsyncFuture, valueNotifierStreamController, valueNotifierAsyncStreamController, valueNotifierTransform, valueNotifierMerge to facilitate the rapid construction of ValueNotifiers.

Breaking Changes

• viewModels(factory,factory2) : Parameters factory and factory2 are no longer automatically added to ViewModelProvider to prevent memory leaks.
• RefViewModelProvider is no longer a subclass of ViewModel.
• viewModelsByRef(factory2) : The lifecycle parameter of factory2 is changed to AppLifecycle.
• ViewModelStore : The key in ViewModelStore has been adjusted to its type.
