A periodic stream is a special kind of stream in Dart that sends events repeatedly at fixed time intervals. Think of it as a timer that “ticks” and sends data every few seconds or milliseconds. You use periodic streams when you want your app to do something over and over, like showing a clock, sending […]

A broadcast controller is a special type of stream controller in Dart that lets many listeners subscribe to the same stream at once. Unlike a regular stream controller, which allows only one listener, a broadcast controller supports multiple listeners receiving the same events. You use broadcast controllers when you want to send data or events

A multi-subscription stream lets many listeners receive the same events from one source. Unlike single-subscription streams, where only one listener can subscribe, multi-subscription streams allow several parts of your app to listen at the same time. You use multi-subscription streams when you want to share data or events with multiple listeners. For example, in a

A StreamController in Dart lets you create and control a stream by hand. You decide what data goes into the stream, when it goes in, and when it ends. This is useful when you don’t have data ready all at once. Instead, you want to send data step by step — like game updates, user

A Future in Dart is a way to handle a value that will be available later. It represents a task that takes time to finish, like loading data or waiting for a result. Sometimes, you want to turn this single future value into a stream — a sequence of events that you can listen to.

An iterable is a collection of items you can go through one by one, like a list or a set. It holds data in order, and you can loop over it easily. In Dart, you can turn an iterable into a stream — a sequence of events that send data over time. Creating streams from

A single data stream is a stream that sends just one piece of data and then closes. Unlike streams that send many values over time, this one sends only one event. You might use a single data stream when you want to deliver a simple message or result in a way that fits with other

In Dart, a Stream is like a path where data travels one piece at a time. You can listen to the stream and react when new data arrives. It’s useful when working with things that happen over time, like typing, loading, or network data. An Empty Stream is a stream that sends no data at

In Dart, streams are a way to handle many pieces of data that come over time. Instead of getting all the data at once, streams let you work with data as it arrives, one piece at a time. Think of streams like a river. Just as water flows continuously in a river, data flows in

NaN means “Not a Number.” It happens when a calculation does not give a real number. For example, dividing zero by zero or taking the square root of a negative number can create NaN. In Dart, NaN is a special value used to show that a number is not valid. It helps your program know
