Remarks
Dart is an open-source, class-based, optionally-typed programming language for building web applications--on both the client and server--created by Google. Dart's design goals are: Create a structured yet flexible language for web programming.• Make Dart feel familiar and natural to programmers and thus easy to learn.• Ensure that Dart delivers high performance on all modern web browsers and environments ranging from small handheld devices to server-side execution.• Dart targets a wide range of development scenarios, from a one-person project without much structure to a large-scale project needing formal types in the code to state programmer intent. To support this wide range of projects, Dart provides the following features and tools: Optional types: this means you can start coding without types and add them later as needed.• Isolates: concurrent programming on server and client• Easy DOM access: using CSS selectors (the same way that jQuery does it)• Dart IDE Tools: Dart plugins exist for many commonly used IDEs, Ex: WebStorm.• Dartium: a build of the Chromium Web Browser with a built-in Dart Virtual Machine• LinksThe Dart Homepage•

Returning a Future using a Completer
Async and Await
https://riptutorial.com/8 See example on Dartpad: https://dartpad.dartlang.org/11d189b51e0f2680793ab3e16e53613cConverting callbacks to Futures
Dart has a robust async library, with Future, Stream, and more. However, sometimes you might run into an asynchronous API that uses callbacks instead of Futures. To bridge the gap between callbacks and Futures, Dart offers the Completer class. You can use a Completer to convert a callback into a Future. Completers are great for bridging a callback-based API with a Future-based API. For example, suppose your database driver doesn't use Futures, but you need to return a Future. Try this code: If you are using an API that already returns a Future, you do not need to use a Completer.

Examples
Creating a class
Classes can be created as follow:
The class can be instantiated using the keyword after which the field values will be null by default.Field values can then be accessed:
Members
A class can have members.
Instance variables can be declared with/without type annotations, and optionally initialized. Uninitialised members have the value of , unless set to another value by the constructor.Class variables are declared using the keyword.
If a method takes no arguments, is fast, returns a value, and doesn't have visible side-effects, then
https://riptutorial.com/10 a getter method can be used: Getters never take arguments, so the parentheses for the (empty) parameter list are omitted both for declaring getters, as above, and for calling them, like so: There are also setter methods, which must take exactly one argument: The syntax for calling a setter is the same as variable assignment:Constructors
A class constructor must have the same name as its class.Let's create a constructor for a class Person:
The example above is a simpler, better way of defining the constructor than the following way, which is also possible: https://riptutorial.com/11 Now you can create an instance of Person like this: Read Classes online: https://riptutorial.com/dart/topic/1511/classes https://riptutorial.com/12Chapter 4: Collections

Creating a new List
Lists can be created in multiple ways.
