JIT and AOT: 1. JIT: 1. Compiles just during hot reload, on the fly. 2. Includes all the code 3. takes less time 2. AOT: 1. Compiles all at compile time 2. Used when we need to build a production application 3. Takes more time, and creates a smaller build including only the code and libraries that are actually used by the app. 3. https://medium.com/@onuohasilver9/how-does-jit-and-aot-work-in-dart-cab2f31d9cb5

MaterialPageRoute( builder: (context) => Page2() ) Flutter streams 1. Types of streams: - Single subscription: Single subscription streams are meant to deliver events in order. This type of stream is used when order of events received matters like reading a file. Such type of Streams can be listened only once. Attempting to listening them again will throw an exception. - Broadcast (Multiple subscribers): Broadcast streams are intended to deliver events to their subscribers. Any subscriber can start listening to events as soon as they subscribe to it. A Broadcast stream can be listened multiple times. 2. Note: A Single Subscription stream can be converted into broadcast streams by using asBroadcastStream() method.
