getStoreHandlers method
If you need more fine-grained control over store trigger handling, override this method to return a Map of stores to handlers. Whenever a store in the returned map triggers, the respective handler will be called.
Handlers defined here take precedence over the redrawOn handling.
If possible, however, redrawOn should be used instead of this in order
to avoid keeping additional state within this component and manually
managing redraws.
Implementation
Map<Store, StoreHandler> getStoreHandlers() {
return {};
}
