Think of threads as tiny workers inside your Python program. Each one has a job to do, like fetching water or delivering messages. Just like people, threads have a lifecycle—they start out new, get to work running their tasks, and then finish when their job is done. In this article, we’ll follow these little workers […]

Have you ever wanted your Python program to do two things at the same time — like download cat photos and play your favorite tune in the background? That’s exactly what threads are for. In Python, threads let your program multitask — kind of like a circus juggler handling flaming swords while riding a unicycle.

Filtering a stream means picking only some events from it based on rules you set. Instead of using every value that comes, you choose which ones to keep. This helps you work with just the data you want, making your program cleaner and easier to control. For example, you can filter to get only even

Reducing a stream means taking many pieces of data that come from the stream and combining them into one single value. Imagine you have a list of numbers flowing one by one. Reducing lets you add them all up or join them into one string. It’s like gathering small parts to make a whole. In

In Dart, “mapping” a stream means changing the data that flows through it. You take each item in the stream and transform it into something else. For example, you can take a stream of numbers like 1, 2, 3 and turn them into emojis like ⭐️, ⭐️⭐️, ⭐️⭐️⭐️. This is done using the .map() method.

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.
