The Stream class in Dart is used for handling asynchronous data sequences. It is particularly useful for managing data that arrives over time, such as user inputs or data from external sources. Streams can be single-subscription or broadcast, depending on whether multiple listeners can subscribe to the same stream.
Ideal candidates should explain the basic concepts of streams, including listening to a stream, handling data events, and managing errors. They should also discuss practical scenarios where streams are beneficial, such as real-time data updates.
