- Method Detail
  - onSuccess
```
 abstract Unit onSuccess()
```
    Invoked when the evaluation context update completes successfully.
    This method is called on a background executor thread after the state transitions to FlagsClientState.Ready. The new flag evaluations are now available for subsequent flag resolution calls.
  - onFailure
```
 abstract Unit onFailure(Throwable error)
```
    Invoked when the evaluation context update fails.
    This method is called on a background executor thread after the state transitions to either FlagsClientState.Stale (network failed but cached flags available) or FlagsClientState.Error (network failed with no cached flags).
    
    Parameters:
    
    error - A Throwable containing details about the failure, typically including a message explaining the network request failure.
