How does the Merge operator differ from Combine in the RxDart library?

In RxDart, the merge operator combines multiple streams into one, with elements from all source streams arriving in the resulting stream as they appear, without waiting for other streams.

The combineLatest operator (called combineLatest or combineLatestStream in RxDart) combines streams so that each time a new value appears in any of the streams, it emits a combination of the latest values from all streams.

Example of the difference:

• merge: if there are two streams A and B, then all events from A and B will appear in the resulting stream as they occur.
• combineLatest: if there are two streams A and B, then the result will be a stream that emits a tuple of the latest values of A and B each time a new value appears in any of them.

Thus, merge simply combines events, while combineLatest synchronizes streams based on their latest values.
