Missing test cases for router state preservation after configuration changes
The current test suite does not include test cases that verify the state preservation of
ChildStackRouterwithin theRootStackRouterhierarchy after multiple configuration changes, as described in issue #100. Consider adding these tests to ensure the issue is fully resolved.🔗 Analysis chain

1-62: Verify the solution against the original issueThe changes made to
DefaultStateKeeperDispatcherlook promising in addressing the state loss issue after multiple configuration changes. However, it's important to verify if these changes fully solve the problem described in issue #100, particularly in the context of theRootStackRouterandChildStackRouterhierarchy.To ensure the changes effectively solve the issue, please run the following verification steps:
- Set up a test scenario mimicking the
RootStackRouterandChildStackRouterhierarchy described in issue Updated gradle-setup-plugin #100.- Implement multiple configuration changes (e.g., switching between Dark and Light themes).
- Verify that the
ChildStackRoutermaintains its stack after these configuration changes.If these tests don't exist, consider adding them to ensure the issue is fully resolved.

24-24: Improved readability withserializeAndDeserialize()The change simplifies the serialization and deserialization process, enhancing code readability. This is a good improvement that potentially reduces code duplication across tests.
Consider adding a brief comment explaining what
serializeAndDeserialize()does, especially if it's defined in another file. This would improve code clarity for other developers.
37-59: New test method effectively addresses the PR objectiveThis new test method is a valuable addition that directly addresses the issue of state loss after multiple configuration changes. It effectively simulates multiple recreations of the state keeper and verifies the correct restoration of both overwritten and unchanged data.
To further improve the test's readability and maintainability:
- Consider adding brief comments explaining the purpose of each dispatcher creation and state save/restore operation.
- You might want to add an assertion to verify that
key2was not consumed indispatcher2, to explicitly show that it remains unchanged throughout the process.

9-9: Improved state handling in the constructorThe initialization of
savedStateas a mutable map is a good improvement. It allows for more flexible state management and aligns with the PR objective of addressing state loss issues after multiple configuration changes.
15-16: Enhanced state preservation in thesavemethodThe modification to initialize
mapfromsavedStateis an excellent improvement. It ensures that existing state is preserved when saving, effectively addressing the issue of state loss after multiple configuration changes. The use oftoMutableMap()is a good practice to prevent unintended modifications to the originalsavedState.state-keeper/src/commonTest/kotlin/com/arkivanov/essenty/statekeeper/DefaultStateKeeperDispatcherTest.kt (1)
