OmegaScope class
Dependency container: exposes channel and flowManager to the whole UI via inheritance.
Why use it: Screens need the channel to emit events and the flowManager for
handleIntent and getFlow. By wrapping the app with OmegaScope, any child can use OmegaScope.of.
Example: OmegaScope(channel: r.channel, flowManager: r.flowManager, initialFlowId: r.initialFlowId, child: MaterialApp(...));
