• Moved the examples to the package's repository.

Most of the references to BLoC were removed from the package to allow any implementation for state management: custom BLoC, BLoC or Cubit from the bloc package, ChangeNotifier, or anything else. Deprecated typedefs to the older classes and deprecated aliases to older members were added to soften the change.

This is a short-lived major version to migrate from those deprecated API to the new one but to still be able to run your app in the process. Every deprecation in this version is scheduled for removal in v0.8.0.

• BREAKING: While removing references to BLoC, named arguments to some constructors and methods could not be easily backed by anything backward compatible, and they were hard-renamed:
  • PageStackPageBlocEvent:
    • was renamed to PageStackPageEvent.
    • bloc was changed to PageStateMixin state.
    • pageBlocEvent was renamed to pageEvent.
  • PageStacksPageStackBlocEvent:
    • was renamed to PageStacksStackEvent.
    • bloc was renamed to stack.
    • pageStackBlocEvent was renamed to pageStackEvent.
  • MaterialPageStacksRouterDelegate.pageStacksBloc was changed from a named constructor argument to a positional one and renamed to pageStacks.
  • PageStackNavigator.bloc was renamed to stack.
• BREAKING: PageStack.pages is now an UnmodifiableListView and not the actual list.
• Renamings backed by deprecated typedefs and member aliases that are thus non-breaking:
  • PageBloc was changed to PageStateMixin mixin. To continue using custom blocs as in the previous versions, mix it in with with keyword instead of extending PageBloc. The newly deprecated PageBloc is changed to mix in this mixin.
  • PageBlocEvent was renamed to PageEvent.
  • PageBlocPathChangedEvent was renamed to PagePathChangedEvent.
  • In enum PopCause:
    • pageBloc was renamed to page.
    • pageStackBloc was renamed to pageStack.
  • PageBlocPopEvent was renamed to PagePopEvent.
  • PageStackBackButtonDispatcher.pageStackBloc was renamed to pageStack.
  • PageStacksBackButtonDispatcher.pageStacksBloc was renamed to pageStacks.
  • PageStackBlocEvent was renamed to PageStackEvent.
  • PageStackRouterDelegate.pageStackBloc was renamed to pageStack.
  • PageStacksBloc:
    • was renamed to PageStacks.
    • currentStackBloc was renamed to currentStack.
  • PageStacksBlocEvent was renamed to PageStacksEvent.
  • PageStacksRouterDelegate.pageStacksBloc was renamed to pageStacks.
  • CAbstractPage.bloc was changed to PageStateMixin.state.
• PageStackEvent now has type parameter <P extends PagePath>.
• PageState class is added as the default class that uses PageStateMixin.
• All classes using C prefix were changed to P prefix. Deprecated typedefs added for backward compatibility. That prefix was historical when the term 'configuration' was used instead of 'path'. The new P stands for 'path'. These classes are meant for apps that have a common superclass under PagePath. All other apps should use the same classes without prefixes.

• Added PageStacksConfigurationChangedEvent.

• Preserves the state on browser refresh button press by using https://pub.dev/packages/flutter_issue_108697_workaround
• Renamed PageStackBlocNavigator to PageStackNavigator. A deprecated typedef was added for backward compatibility.

• Added PageStackRouterDelegate.observers, PageStackRouterDelegate.transitionDelegate.

• Added PageStackBlocNavigator.observers, PageStackBlocNavigator.transitionDelegate.

• Updated example links.

• Added PageStackBloc.popUntilBottom(), it uses the new PopCause.pageStackBloc.
• PageBlocPopEvent is now always created with the correct R type. Before it had been
• const PageBlocPopEvent<Null> for pops without data.
• Improved test coverage.
• Fix formatting.
• Add comparison to auto_route and go_router to README.

• Added PageStackBloc.replaceWith to declaratively navigate to a given path with two options:
  • Replacing the stack unconditionally with mode: PageStackMatchMode.none.
  • Preserving the states of pages that exist in both the old and the new stack with mode: PageStackMatchMode.keyOrNullPathNoGap.
• Added mode argument to PageStackBloc.setConfiguration to choose the match mode the same way as in replaceWith.
• Added PageBlocCloseEvent.cause to tell between the back button close, the bloc's own intention to close, and a kick-out as a result of stack diff.
• BlocMaterialPage is now non-abstract.
• Fixed issue when page stack was allowed to be emptied and stayed defunct afterwards Issue 3. The emptying operation is now reverted.
• Removed code duplication by handling all page removals in PageStackBloc.handleRemoved().
• Expand tests.

• Renamed PageBlocCloseEvent to PageBlocPopEvent to align with didPopNext method.
• A deprecated typedef was created for backwards compatibility.

• Renamed PageConfiguration to PagePath. A typedef for backwards compatibility is added. Methods, getters, and arguments with pages' 'configuration' in its name were changed to use 'path', deprecated copies of the old ones were added for backwards compatibility. The PageConfiguration's name was a permanent source of confusion. Each doc had to start with a note that PageConfiguration corresponds to a URL, and it was not easy to memorize. This change will simplify the learning of this package. It has also stripped 9-13 characters from identifiers. Path is inspired by the original article announcing Router API (as well as app_state name itself was). Configuration earlier was inspired by Router docs where it means the configuration of the whole app (earlier versions of app_state were designed to allow storing only the top page's state, and so 'configuration' was extended to pages as well). 'Configuration' is still used in PageStackConfiguration and PageStacksConfiguration class names that do represent the whole app's state, and that is correct.
• Deprecated PagePath.restoreRouteInformation. It used to allow overriding state and was confusing because it was not used in serializing for browser history (super.state is).

• Fix images in README.

• BREAKING: All classes that had a type parameter <C extends PageConfiguration> no longer have it. The idea of this type parameter is to have a subclass that is a superclass to all of your configurations. An example is when you store a language slug there, and it must be automatically present in all your configurations. These cases are rare, and most of the time <PageConfiguration... only clutters the code when you must provide some other typed parameters like PageBloc type or the return value. All such classes were renamed in a pattern of PageBloc<C, R> -> CPageBloc<C, R>. Then typedefs were added like typedef PageBloc<R> = CPageBloc<PageConfiguration, R>. If you need the common subclass of PageConfiguration, just add C before all such typed parent classes to get it back. Otherwise just remove <PageConfiguration> from your code.
• BREAKING: When PageStackBloc compares pages to null PageConfiguration, it ignores the page keys and never disposes such pages. This is to allow non-web apps without any PageConfiguration classes. Otherwise the pages were always kicked out when comparing to null PageConfiguration. No practical use cases were affected.
• PageConfiguration classes are now optional for all non-web apps and web apps that do not care for URLs.
• PageConfiguration is now non-abstract and has / as the default location.
• PageConfiguration objects no longer need to parse RouteInformation.state in their tryParse. To benefit from this, stop overriding parseRouteInformation in your parser and override one of the new methods instead: parsePageConfiguration, PageStackRouteInformationParser.parsePageStackConfiguration, PageStacksRouteInformationParser.parsePageStacksConfiguration. These methods are only called when failed to extract state from RouteInformation, i.e. when the URL is typed in, and so no non-URL state information is present.
• PageStackConfiguration.getTopPageConfiguration() is now nullable and returns null if none of the pages in the stack have PageConfiguration.
• PageStackRouteInformationParser and PageStacksRouteInformationParser can now be used without subclassing in all non-web apps and web apps that do not care for URLs. By return they parse null PageConfiguration objects.
• PageStackRouteInformationParser and PageStacksRouteInformationParser in their restoreRouteInformation now return all their stack/stacks states to store in browser history and not only that of the top PageConfiguration.
• Added const constructors to PageStackRouteInformationParser and PageStacksRouteInformationParser.
• PageStackRouteInformationParser and PageStacksRouteInformationParser now have parsePageConfiguration to only parse the single PageConfiguration. This way the superclasses call defaultStackConfiguration and defaultStacksConfiguration so you don't have to. They are the recommended replacements to respective parseRouteInformation methods. They are called only when failed to recover from RouteInformation.state. To use them, stop overriding parseRouteInformation.
• PageStackRouteInformationParser now has parsePageStackConfiguration, and PageStacksRouteInformationParser now has parsePageStacksConfiguration. They are the alternative replacements to respective parseRouteInformation methods in case you need additional logic to recover the stack state that cannot be derived from your PageConfiguration alone. They are called only when failed to recover RouteInformation.state. To use them, stop overriding parseRouteInformation.

• Added PageConfiguration.location.
• Added PageConfiguration.defaultStackConfigurations.

• BREAKING: Pages, Blocs an PageBlocCloseEvent have a new R type parameter for the return result. The actual result is of R? with null if closing without data.
• BREAKING: PageBlocCloseEvent has a new required data property of type R. It is encouraged to use it instead of subclassing PageBlocCloseEvent.
• BREAKING: Page classes no longer have const constructors because they have Completers now.
• Added PageBloc.pop(data).
