an_viewmodel: ^3.4.1 copied to clipboard

• Code standardization

• Optimize the search efficiency of ViewModelProvider

• Added support for specifying the type during creation to enable runtime ViewModel instantiation.
• ViewModelProvider.getOrCreate is deprecated, please use getOrCreateViewModel instead.

Breaking Changes #

• All ViewModel functions in ViewModelStore now have an optional vmType parameter.

• Optimize the cleanup timing of _MergingValueNotifier.

• 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.
• ViewModel.doNotAssertProviderProducer is used for compatibility when upgrading from v2 to v3, to prevent asserting and checking the validity of the ProviderProducer.

Breaking Changes #

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

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

• Upgrading Dependencies.

• Add more proactive notifications to valueNotifierStreamXXX when notifyWhenEquals=true.

• BuildContext.withLifecycleAndViewModelEffect allows executing lifecycle-related functions based on the current context and ViewModel.
• Optimize the usage of ViewModelProviderProducer.

• Added makeCloseable to provide cancelable based on viewmodel lifecycle.
• 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.

• Migrate from an_lifecycle_viewmodel.
