Dart Console App

Flutter is an innovative framework that allows developers to create high-quality mobile and web apps. Business logic component (BLoC) patterns allow Flutter applications to manage application state. 

You'll learn about the BLoC pattern and implement a counter application using streams, events, and states from the BLoC architecture. Next, you will learn to use different widgets provided by the BLoC library that help reduce the boilerplate code. You'll then implement a Star Wars project using the flutter_bloc library and an e-commerce platform using the repository pattern alongside the BLoC pattern. You'll also learn to create mocks to test different blocs using the bloc_test library. You'll also learn to test the functions inside a bloc. Next, you'll learn about the RxDart library that provides reactive programming extensions to streams.

By the end of this course, you'll get hands-on experience with BLoC and RxDart libraries that will equip you to build a mobile or web application with a managed state.

Managing State in Flutter Using BLoC Pattern

It's a notification that a stream has completed its work and will not emit any more events.

It's a notification that a stream has encountered an error.

It's a notification that a stream has new data to emit.

What does a completion signal in RxDart indicate?

What does a completion signal in RxDart indicate?

To concatenate multiple streams into a single stream

To delay the creation of a stream until a listener subscribes to it

To repeat a given event a specified number of times

To react to changes in multiple data sources at the same time

When should you use `CombineLatestStream`?

When should you use <code>CombineLatestStream</code>?

Which stream class is used to fetch data from multiple APIs before displaying the results?

Which stream class is used to fetch data from multiple APIs before displaying the results?

Which extension method applies an accumulator function to each item emitted by a source stream, sequentially, and emits each intermediate result?

Which extension method applies an accumulator function to each item emitted by a source stream, sequentially, and emits each intermediate result?

Which method is called when the stream finishes emitting items?

Which method is called when the stream finishes emitting items?

To provide context to new subscribers about missed events

To control the flow of events in a stream

What is the main purpose of `BehaviorSubject` and `ReplaySubject` in RxDart?

What is the main purpose of <code>BehaviorSubject</code> and <code>ReplaySubject</code> in RxDart?

When subscribing to a `BehaviorSubject`, if a listener is added after events have been emitted, what value will the new listener receive as the first item?

When subscribing to a <code>BehaviorSubject</code>, if a listener is added after events have been emitted, what value will the new listener receive as the first item?

When subscribing to a `ReplaySubject`, if a listener is added after events have been emitted, what values will the new listener receive as the first items?

When subscribing to a <code>ReplaySubject</code>, if a listener is added after events have been emitted, what values will the new listener receive as the first items?
