getState method
Returns the Event for the given typeKey and optional stateKey.
If no stateKey is provided, it defaults to an empty string.
This returns either a StrippedStateEvent for rooms with membership
"invite" or a User/Event. If you need additional information like
the Event ID or originServerTs you need to do a type check like:
if (state is Event) { /*...*/ }
Implementation
StrippedStateEvent? getState(String typeKey, [String stateKey = '']) =>
states[typeKey]?[stateKey];
