| 1 | What is a Stream in Dart, and how does it differ from a Future in terms of how many values it can actually provide over time? Flutter › Dart Streams & StreamControllers | Flutter | Dart Streams & StreamControllers | Beginner |
| 2 | What is the difference between a single subscription stream and a broadcast stream in Dart, and when would you specifically need to use a broadcast stream instead? Flutter › Dart Streams & StreamControllers | Flutter | Dart Streams & StreamControllers | Intermediate |
| 3 | How do stream transformation methods, such as map, where, and distinct, let you process and filter the values emitted by a Stream, similar to how these same methods work on a regular Dart collection? Flutter › Dart Streams & StreamControllers | Flutter | Dart Streams & StreamControllers | Intermediate |
| 4 | How does the listen method let you subscribe to a Stream and react each time it emits a new value? Flutter › Dart Streams & StreamControllers | Flutter | Dart Streams & StreamControllers | Beginner |
| 5 | What is a StreamController, and how does it let you manually create and control your own custom Stream, pushing values into it yourself whenever you choose to? Flutter › Dart Streams & StreamControllers | Flutter | Dart Streams & StreamControllers | Intermediate |
| 6 | How does the StreamBuilder widget in Flutter let you build a reactive user interface that automatically updates whenever a Stream emits a new value, without needing to manually manage the underlying subscription yourself?

| 7 | What are common StreamTransformer patterns, such as debounce and throttle, and how do they help control the actual rate at which a stream's events are processed, particularly for something like a rapidly typed search query?

| 8 | What is a Future in Dart, and how does it represent a value that will not actually be available until some point later in time? Flutter › Dart Asynchronous Programming (Future & async/await) | Flutter | Dart Asynchronous Programming (Future & async/await) | Beginner |
| 9 | What is the BLoC pattern, and how does it genuinely separate your app's own business logic from its user interface using genuine Streams and events? Flutter › State Management with BLoC & Cubit | Flutter | State Management with BLoC & Cubit | Beginner |
