FlowRedux Files

• New artifact coordinates: com.freeletics.flowredux2:flowredux:<version>.
• New package name: com.freeletics.flowredux2

General changes:

• The main class to define ypur state machine is now FlowReduxStateMachineFactory which can be started with launchIn (Coroutines) or produceStateMachine (Compose). Both return an active FlowReduxStateMachine that allows dispatching actions to it and observing the current state.
• The old compose artifact was removed in favor of the mentioned produceStateMachine.
• FlowReduxStateMachineFactory offers various StateHolder classes that allow to keep the previous state for the next startd state machine. By default the previous state will be kept in memory (inMemoryStateHolder). Other APIs allow to just drop the previous state (lossyStateHolder) or use SavedStateHandle to persist the previous state (savedStateHandleStateHolder, serializableStateHolder, parcelableStateHolder).
• The old FlowReduxStateMachine is available as LegacyFlowReduxStateMachine for now.

DSL:

• The State class that has the override, mutate and noStateChange methods is now called ChangeableState and is the receiver in each DSL block instead of being passed as a parameter. Like before ChangeableState allows access to a snapshot state.
• ...Effect methods now have a State class as receiver that allow accessing snapshot instead of receiving snapshot as a parameter.
• It's now forbidden to access snapshot in the override and mutate methods to avoid accidental bugs where outdated state is used to build the new state.

Other:

• ...Effect DSL methods won't cause the previous state to be emitted again when they complete.
